Yeah there great for just going from point a to point b a guy at my work has a s10 and the 4.3 on it has 300/000 miles still original injectors in it but everyone has there preference
👍 I've only done one gm tbi to carb ...it was a 84 corvette with the cross fire tbi you made it seem way easier than what I dealt with...the corvette was a pain in the butt
Thanks, this is the best @ the more easy tbi to carb swap I have seen. You set my mind at ease. I have 94 5.7 tbi with 4l60e that I have to deal with on that shift module, but I'll worry about that when I get to it. THANKS YOU!!
Awesome job Sir! Carb For the win! Sounds so Sweet with that summit carb. I love that air filter too. I wish I had clearance for it. You know your stuff Sir! Carb is where it's at. I liked that saying. I took my choke completely off.
The square bodies were the last Chevy & GMC fullsize trucks to have carburetors & they were also the first to have fuel injection too. 1986 was the last year for carburetors & 1987 was the first year for fuel injection. 1988 was the first year for those OBSs.

We can always learning something from Chris. Even though I am NOT a "car person" myself (that would be Steven, not me), I feel that I learn something every time I watch Mr. Chris. This thought just came to me -- this thought just came to me right now as I am writing: CHRIS WOULD MAKE AN EXCELLENT HIGH SCHOOL SHOP INSTRUCTOR! One of the things that impresses me is the way that he explains all of his work so clearly and plainly. He really has great narration skills --- and I am not just "blowing smoke" either.

Great video and very informative! My dad and I are in the planning stages of a carb swap in our 92 with a 700r4 and this video will help a bunch. Your truck looks and sounds great!
@@CCAutoWorks Been good! Me and my nephew tore down the 4l80e this morning finally. Gonna be doing the reassembly throughout this coming week. I'll be filming that.
I think the GM TBI units were 410 cfm and 460 cfm so it should have a good bit more high end power. Assault racing is headquartered about 40 miles north of me, they got a great holly blue knock off pump if you ever need one. We are gonna try their electric water pump on the 460
Thanks for the info Jim hopefully you make a video on what you think about there water pump because I've been thinking about a set of there sbc heads to
Sweet video brother, the info will come in handy down the road. Got a question for you or anyone who reads this. This is the situation I'm in. I recently bought a 77 Sierra Classic K15 for a project truck it's 98% complete. It's not running. The original 400 sbc engine, turbo400 transmission and transfer case were removed and replaced with a 5.7 tbi smallblock and 700r4 tranny out of a 87 suburban. The setup was only dropped in and nothing hooked up, it's all just sitting in there I'm not great with with computers and not a fan of fuel injection and want to put this old girl back to a carburetor the way she came from the factory. I'm going the way of a mechanical fuel pump, so other than that I need the intake for vortec heads, a carburetor and hei distributor. How difficult to get that 709r4 tranny working, it's not electronically controlled? I would be setting it up like a TH350 or TH400 correct?
One an 87 suburban isn't a vortec so no need for a vortec intake manifold 87 is tbi and the tbi heads use the regular sbc intake you just have to drill the bolt holes a tad bigger sometimes and for the 700r4 you just need a throttle bracket for the detent kickdown cable for the 700r4 and you need a vacuum switch for the converter lockup once it's in overdrive or I've seen some people just use a taggle switch but I like the vacuum switch so it does it on its own no worries
What intake manifold did you use? I just watched another video and they had an issue with the aftermarket intake being too big and hitting the stock heads.
What size carb are you using? Are you running it straight out of the box? What year is your truck? My 91 doesn't have tach. I'm either gonna do a complete custom gauge set up or it would be nice if I could find one like yours at a pull a part
Mine has a tach because it's manual transmission it's a 92 and it's a summit racing max performance 650cfm that I've tuned a little bit but it still ran right out of the box
got question for you ....i just rebuild my chevy 350 1990 k5 blazer i converted it over from tbi to carb ..i did a few up grade on the engine high performance intake headers 3' pipes all way back up graded the cam to a howard rattler cam 525 intake lift 535 exhaust duration 227/235 lobe separation 109 center line 103 i still the same factory heads on there i believe they the swirl port heads ..i no i should have went with some better heads but the engine was already done. i put a brand new 1406 edelbrock car on it right out the box every sence i put that carb on there i been using alot of fuel i set the carb best as posible ..im using a awful lot of fuel just with it iding..i have my pressure regulator set at 5psi..dont no why im losing so mush fuel
It's all to do with the cam size and the lsa and the vacuum the cam makes we have other videos where we deal with this problem running a rattler cam on my little brothers mustang you need to buy stepup springs for the carb and possibly drill tiny holes in the throttle blades as a old school trick to lean it out
Just starting tearing down the top end of my 350. Has tick in the top end before I parked it for the winter went to go start it up to diagnose and I had no spark or fuel. So now I’m planning on going to carb and I’ve got a fuel regulator, 2101 edelbrock performer intake, hei distributor and a 650 quadrajet ready to go when I figure out what the tick is. Any advice?
Probably a lifter tick I'd try adjusting the rockers it might have pulled a rocker stud a tad bit or a lifter collapsed but adjusting the rockers should get rid of tik if not it might be deeper like a spun rod bearing
Hey man, did you have any issues with swapping to vortec heads? Im currently in the process but dont know if i should port the tbi heads or go the extra foot and get vortec heads and port those? My main concern is the fitting from the alternator brackets etc but mines looks just like yours so im not too concerned just dont know how to run the heater hose and etc..
They bolt right up no problem all the tbi brackets bolt right up you will just need a intake for vortecs and the heater hoses are no big deal there very simple to figure out
Nice video .. i have 90 silverado 7.4 th400 and i slapped a holley in it and my question is do i need the ignition control module, tps , map sensor,oxygen sensor? Also on the fuel it runs but shuts off but if i step on the pedal it would stay on untill i let go so what can i do ?
Ok so which Holley regulator would I need to make this work with running the stock fuel pump? Would I need to go with the one rated for higher psi ( 50-60) or would I got with the lower one ( 4-9 ) ?? I’m just confused on which I would need. I bypassed my stock pump and used a Edelbrock micro pump but I’m having issues now. When using the stock pump it just shoots fuel out of my carb. I don’t know if it is because of the regulator I got from autozone is too weak or what….any advice?
is it idling a little low? tach is way down there and before i saw that and just heard the startup it sounds a little off...either way thanks for the video - swapping a friends tbi to carb so clarified a few questions/concerns
So im picking up a 350 sbc and its already carb but its off a nova and i want to throw it in my 91 with a 700r4, my question is do i need a new harness ? or how will i make it work TIA
No you don't need a new harness carbureted engine really doesn't need anything more the one ignition wire to run other than the starter wiring and the harness you have will hook to all your sensors so your gauges will still work
The 4l60e can be wired to the hei and using the tps sensor kit for the holley carbs to run just fine without a stand alone or anything and everything still works like this
@@CCAutoWorks yea I always was too, it kept me from swapping my 98 z71 vortec, but there's a few videos on here that show how to wire it up to an hei. 1 in particular but can't remember the title but yea that made my day lol Doesnt look much different then then the tbi wiring other then the crank sensor the vortec has but that is 1 you wire in to the hei for the signal instead of leaving it connected to the sensor
@@CCAutoWorks not to much different from the tbi its fairly simple. I think the crank sensor and possibly a different fuel regulator 🤔 depends on the 1 you used for this can handle the higher psi for the vortec pump but I know they make the 1 that does just not sure if its different then this 1 lol
Hey I got a 89 tbi camaro and it doesn’t have center bolt heads I forgot I should be able to use old style carb intake right or would I need the four middle bolts angled
No mines manual but you start by just taking all the slack out of the cable if u want it to hold shifts longer put a little more tension on the cable but u also need a way to lock the converter
@ C&C Auto Works, where did you get your electric cooling fans and what part number and or year model are they off of? I have a 88 GMC Sierra SLE K1500 with 5.7L, and 700R4 trans that I'm completely converting over with a rebuilt 350 engine with stock flat top pistons, a set of 350 non-swirlport L98 cast iron heads with casting #14100183, Speed master dual plane intake, Lunati Street Master cam #301A6, 750 CFM Quadrajet carb, may change to over to a Holley 650 CFM Brawler carb later, HEI distributor w/vacuum advance, Hedman long tube headers, 2-1/2 in dual exhaust, 3.73 rear gears, may go with electric water pump later, and I'm definitely using a dual radiator electric cooling fan assembly if I can find one that'll work in my truck that looks like factory if possible. I noticed the electric cooling fan in your truck and it looked like it was factory. Good job on the TBI to carb change over.
me and u got same engine i got the 1990 k5 blazer i put a i got 2 temperature. switches one in side of head on driver side and the other one mounts in the front intake on the side of thermostat housing..i no the one thats in the head i no thats for my gauge thats on my dash board.so sense im eliminating the computer do you still use that temp.wire going to thte switch..and i have a 700r4 trans i up graded my cam with howard cam ratter 188005-09 lift .525/530 duration 227 / 235 centline 103 i also upgraded my torque convert to 2000 to 2400 stall ..do i have to get a converter lockup controller i dont want to burn my trans up ..i seen a video on here where they took a wire to one of the plugs coming out of the harness..so i may not need that converter lockup what did you do with your engine..
My trans is manual but yes a 700r4 has to have a vacuum lockup switch TCI sells them and I think this temp wire for the gauge will still work without the computer but I left my computer in
Yes fits in a factory vortec roller block only thing you need to check is your valve guide clearance you might need to cut your valve guides down a little
Brailsfords if your really thinking about doing something like this to the fox I've got another video doing this to my 92 f150 and it would be more like your fox
good video my brother ..i no what u mean about getting a chip burn i have a 1990 k5 blazer 5.7 just got it rebuild and did alot of up grades 3704 edelbrock intake headers bigger cam xe 262h comp cam tbi spacer injector spacer change the factor regulator spring to 18psi spring put a gauge on the back of the tbi got adjustable cover so i can adjust it i got 700r4 trans in there ..i up graded my torque converter to a 2000 to 2400 stall 4.10 gears i had someone to custom burn my chip and i could not get it to run right i couldnt never get the fuel right i just didnt have no power..and i up graded my fuel pump to the vorect pump the tuner was a good tuner... but its hard to get someone to get it right if they in another state they have to have some kind of data log to get it right i wish i would had did what you did at frist ..so right now im trying to decide wish way to go carb. or efi sniper...
Your right the chips are a head ace sounds like you have va nice build though I would save yourself some money and a head ace and put a carb on it I've heard good and bad about the efi units but if you have much of a cam they seem to have a hard time learning
@@CCAutoWorks you are absolutely right about that...i have heard and read alot of people having promblems with them efi and i dont have time to call holley and summit and edelbrock and wait on the phone for hours to get some one to help you... and im pretty sure you no what i im talking about..plus it will be less money and less problems
@@thedobermangang3503 the biggest problem is on the efi units is even the people making them don't ha answers alot of the times they will just say give it time it's still learning
Hey how are you I’m running something like this on my obs same carburetor I’m useing all must all the same as u but I’m haven a hard time to get my fuel up to 6psi
Im having problems getting my fuel pump to run. I have a 1992 c1500 sport truck that I just installed a 1965 327 sbc. Where do you run the purple/white wire if you have a msd distributor?
I just cut the stock metal lines and slide a rubber fuel hose over and clamped it and the fuel regulator is marked in out and returns out of the bottom
Ive got a 3500 Express with a L31 Vortec 350, and the TBI is starting to give me shit. Considering upgrading the fuel delivery, but that trans module is a huge cost compared to going to a big block TBI on an otherwise stock work van. It usually runs fine snd drives fine, tows with no issues, but when its got problems it just dies and takes a while to get cleared up to run again. Might need the fuel lines replaced too, but that spider under the intake is just a bad design. Its less of a problem on the TBI built for the 454, but still a TBI. What was the total cost to go to virtec heads and run a carb with regulator? I'm definitely not resolved to using a TBI, might go to a 750 cfm carb on a dual plane intake. If i have to pull the engine its getting a lot more work than just that TBI upgrade. Might get a 6.0 4l80E drivetrain at that point.
6.0 4l80 sounds good but back when I done this I pulled the heads from a junk yard for $40 the vortec summit air gap intake was $200 carb was $320 regulator was $55 air cleaner $25 and hei distributor $60 custom ground roller cam was $200 lifters $80
yes, I don't consider the '96 up Vortec an improvement on the TBI at all...much crappier distributor design, crappy spider injectors and plastic intake, and far more electronics and sensors...
So do you not need the computer when you put a 350 in a truck? I’ve been thinking about swapping motors, it’d be easy if I didn’t have to worry about the computer lol
Judging by the color of the pickup I'm going to ask what the hell you're doing under the hood of my truck? LOL mean it's the same color and has a manual transmission. LOL I know the vortec heads are supposed to really breathe a lot better. I'm getting ready to rebuild an engine and put in my truck is the reason I'm asking all the questions. Would you recommend going with a Vortec heads on a TBI rebuild covertes to carb? Thanks for the video
Ahhh what I was looking for. I have an 88.5.7 with SM 465 . I’m so over the TBI and stock dist, but don’t want to lose Cruise control. So you left the harness alone other than DCing the TBI and DIst and the cruise still works? Thanks
I like to thank you for all the Information on the swap. I have one question the truck have a 4160 transmission what would it take to Install the 700R transmission I know the tps control transmission down shift.
Sounds like your timing is off but I did change my distributor gear out for a brass one because of the roller cam or they have a different material distributor gear that's harder then brass but still softer then the cam it starts with a M
Hopefully you see this and maybe I missed it but I just did this to my 87 suburban... what did you do to get the fuel pump to kick on I'm on that last step and have no fuel?
I have a 700R4 in my suburban then I'm trying to do this too. What all would have to be done for the transmission? Is it just the kickdown cable that I have to worry about?
@@rjlittlefield9209 the way I understand it is that it will work as normal as long as your tv cable is set right but the converter won't lock up and it won't get as good as gas mileage because it's not locked but I'm not 100% sure but this is what I've read and heard
and let me say this part of it not running right have alot to do with my friend that rebuild it ..he mess up it was burning oil one of my spark plugs had oil on it and i took it back out and he redid it put it back it and still got the same problem so hes not going to mess with my engine again had to pay me my money back so now im getting everything done again..
The buddy system doesn't always work out but at least he's giving you your money back but I think even with that it still should have run close to right
Do you think it's the rings or maybe a valve seal and I've even seen an intake gasket not seal and suck oil out of the lifter valley into the intake port from the under side on one or two cylinders
I carb swapped my 1994 blazer full size, it stalls after about 5 minutes of run time. I have the fuel regulator at 5 psi and an HEI distributor. It always cranks back up tho. Could that be something electrical that I need to fix?
TBI worked great when new..but after trying everything to solve a random misfire on a 30+ year old truck, to no avail, makes me start wanting to just convert it over to a carb..anything with a computer and sensors, even the older and more simplistic stuff, has too many things interacting and effecting each other...much easier to diagnose and repair if everything is simple and independent of each other..ignition system independent of the fuel system, fuel system independent of ignition, so on and so forth...
Same problem here. 89 4.3. idle stumble, random misfire, ICM failure has gone from once every 2 years to every 2 weeks. I never had these problems with carbed Chevys.
@@fgoindarkgI have an Iroc Tpi 350, how does wiring a carb swap work. As far as fueling can I just keep the stock ecm and wiring and the stock fuel pump in there and then cut into the stock fuel lines in the engine bay and use fuel pressure hoses to hook up to a regulator and to the carb? What other wiring do I need to worry about Trans wiring, ignition wiring too? What’s the least to make it run. Just need someone with experience to give me tips and general answers 😊
i have been told that 1406 carb that i have my engine is pulling quit a bit of vacunnm the jets needs to be change to the smallest ones .095 and put in the fattest metering rods and put in the heaviest springs that will make a big difference on the fuel..
With that cam your running you probably don't have much vacuum at all so it freaks out the card put a vacuum gauge on it see how much vacuum it makes and put the stepup springs in it for the vacuum it's making but you will probably still have to change the rods and jets to lean it out

Sweet video brother, the info will come in handy down the road.
Got a question for you or anyone who reads this.
This is the situation I'm in. I recently bought a 77 Sierra Classic K15 for a project truck it's 98% complete. It's not running.
The original 400 sbc engine, turbo400 transmission and transfer case were removed and replaced with a 5.7 tbi smallblock and 700r4 tranny out of a 87 suburban. The setup was only dropped in and nothing hooked up, it's all just sitting in there
I'm not great with with computers and not a fan of fuel injection and want to put this old girl back to a carburetor the way she came from the factory.
I'm going the way of a mechanical fuel pump, so other than that I need the intake for vortec heads, a carburetor and hei distributor.
How difficult to get that 709r4 tranny working, it's not electronically controlled? I would be setting it up like a TH350 or TH400 correct?
One an 87 suburban isn't a vortec so no need for a vortec intake manifold 87 is tbi and the tbi heads use the regular sbc intake you just have to drill the bolt holes a tad bigger sometimes and for the 700r4 you just need a throttle bracket for the detent kickdown cable for the 700r4 and you need a vacuum switch for the converter lockup once it's in overdrive or I've seen some people just use a taggle switch but I like the vacuum switch so it does it on its own no worries

You might need the tps so it will run the transmission kickdown and on the fuel you might have to wire the fuel pump relay direct
Ok so which Holley regulator would I need to make this work with running the stock fuel pump? Would I need to go with the one rated for higher psi ( 50-60) or would I got with the lower one ( 4-9 ) ?? I’m just confused on which I would need. I bypassed my stock pump and used a Edelbrock micro pump but I’m having issues now. When using the stock pump it just shoots fuel out of my carb. I don’t know if it is because of the regulator I got from autozone is too weak or what….any advice?
You need the Holley bypassed low pressure the 4-9 because the pressure will never go over 9 psi to the carb I can get u a part number if you need
is it idling a little low? tach is way down there and before i saw that and just heard the startup it sounds a little off...either way thanks for the video - swapping a friends tbi to carb so clarified a few questions/concerns
It was a cold start no choke and i never let it warm up it idles around 500 when cold 800 when warm
So im picking up a 350 sbc and its already carb but its off a nova and i want to throw it in my 91 with a 700r4, my question is do i need a new harness ? or how will i make it work TIA
No you don't need a new harness carbureted engine really doesn't need anything more the one ignition wire to run other than the starter wiring and the harness you have will hook to all your sensors so your gauges will still work
Can you pull the ignition power from the factory ignition wire .
As long as it's a switch ignition wire
she sound good my brother
Thank you
Thanks for the helpful video brotha
Thank you for watching

Assuming stock bottom end, do you know HP and Torque numbers with the changes you made?
350 0.030 over flat tops with vortec heads and lt4 hot cam I'm guessing it makes 360/380 at the crank
The 4l60e can be wired to the hei and using the tps sensor kit for the holley carbs to run just fine without a stand alone or anything and everything still works like this
That's awesome I was under the impression you had to use the tps senor and leave the stock computer to wire it in
@@CCAutoWorks yea I always was too, it kept me from swapping my 98 z71 vortec, but there's a few videos on here that show how to wire it up to an hei. 1 in particular but can't remember the title but yea that made my day lol Doesnt look much different then then the tbi wiring other then the crank sensor the vortec has but that is 1 you wire in to the hei for the signal instead of leaving it connected to the sensor
@@CCAutoWorks not to much different from the tbi its fairly simple. I think the crank sensor and possibly a different fuel regulator 🤔 depends on the 1 you used for this can handle the higher psi for the vortec pump but I know they make the 1 that does just not sure if its different then this 1 lol
@@jjmccloud awesome thanks for the info
NO, it can't. Dead wrong. 60e is fully computer controlled. You have no clue what you are talking about.
Hey I got a 89 tbi camaro and it doesn’t have center bolt heads I forgot I should be able to use old style carb intake right or would I need the four middle bolts angled
You should be able to use the old style intake
Ran wires from battery to both wires and still no pump action. Currently at a stand still. Any help would be appreciated.

Doing a 92, any videos on adjusting the cable for the transmission? 700r4
No mines manual but you start by just taking all the slack out of the cable if u want it to hold shifts longer put a little more tension on the cable but u also need a way to lock the converter
What hot wire did use for the electric chock, and to the battery bottom the distributor?
I don't use a chock but for distributor I used a injector wire
@ C&C Auto Works, where did you get your electric cooling fans and what part number and or year model are they off of? I have a 88 GMC Sierra SLE K1500 with 5.7L, and 700R4 trans that I'm completely converting over with a rebuilt 350 engine with stock flat top pistons, a set of 350 non-swirlport L98 cast iron heads with casting #14100183, Speed master dual plane intake, Lunati Street Master cam #301A6, 750 CFM Quadrajet carb, may change to over to a Holley 650 CFM Brawler carb later, HEI distributor w/vacuum advance, Hedman long tube headers, 2-1/2 in dual exhaust, 3.73 rear gears, may go with electric water pump later, and I'm definitely using a dual radiator electric cooling fan assembly if I can find one that'll work in my truck that looks like factory if possible. I noticed the electric cooling fan in your truck and it looked like it was factory. Good job on the TBI to carb change over.
Sounds like a nice build the fans I used or off a Chrysler Pacifica I'll send u a link to a video of when I first put them on

How did you use your stock fule lines? Did you cut them or use them with fittings. If so, could you give my an idea of what fittings i will need?
I just cut and flared them put high pressure efi rubber fuel line
All bad ass swap
Much appreciated
me and u got same engine i got the 1990 k5 blazer i put a i got 2 temperature. switches one in side of head on driver side and the other one mounts in the front intake on the side of thermostat housing..i no the one thats in the head i no thats for my gauge thats on my dash board.so sense im eliminating the computer do you still use that temp.wire going to thte switch..and i have a 700r4 trans i up graded my cam with howard cam ratter 188005-09 lift .525/530 duration 227 / 235 centline 103 i also upgraded my torque convert to 2000 to 2400 stall ..do i have to get a converter lockup controller i dont want to burn my trans up ..i seen a video on here where they took a wire to one of the plugs coming out of the harness..so i may not need that converter lockup what did you do with your engine..
My trans is manual but yes a 700r4 has to have a vacuum lockup switch TCI sells them and I think this temp wire for the gauge will still work without the computer but I left my computer in
Do you remember what the color wire you used for the tach signal?
Not off the top of my head but I'm thinking red with black line but I could double check
Does that lt4 hot cam fit in fact ory block or do ya need to have work done to make clearance
Yes fits in a factory vortec roller block only thing you need to check is your valve guide clearance you might need to cut your valve guides down a little
Awesome video but what transmission controler are you using im in the middle of carb swapping my truck its 93 with 4l60e curious
Mines a 5 speed
So I have a blown 2.5 and looking to replace the motor with a 4.3. What manual transmission you think I should look for
Hm290 or a nv3500 if you looking for more of a performance trans than a T5 out of a third gen Camaro
with the size cam i have what should my vacuum read...its no where near 19 to 21
It's probably around 6/8
Eyyyyyyy, im going to just save this in my to do Playlist lol
Brailsfords if your really thinking about doing something like this to the fox I've got another video doing this to my 92 f150 and it would be more like your fox
@@CCAutoWorks im considering it, need to see how much work and if I'd rather do this than tuneup and fidget with the current system
So I’m new too cars but what could I do too my TBI engine??? And what are the downsides?
Leaving it tbi about all you can do without opening a can of worms is long tube headers and a high flow air cleaner
im thinking should i keep the factory swirl port heads or get the vortect heads or aluminum heads..
I'm probably going to buy blueprint aluminums for mine soon
swirl ports are some of the worst flowing heads in gm history .. durable but no performance 😞
good video my brother ..i no what u mean about getting a chip burn i have a 1990 k5 blazer 5.7 just got it rebuild and did alot of up grades 3704 edelbrock intake headers bigger cam xe 262h comp cam tbi spacer injector spacer change the factor regulator spring to 18psi spring put a gauge on the back of the tbi got adjustable cover so i can adjust it i got 700r4 trans in there ..i up graded my torque converter to a 2000 to 2400 stall 4.10 gears i had someone to custom burn my chip and i could not get it to run right i couldnt never get the fuel right i just didnt have no power..and i up graded my fuel pump to the vorect pump the tuner was a good tuner... but its hard to get someone to get it right if they in another state they have to have some kind of data log to get it right i wish i would had did what you did at frist ..so right now im trying to decide wish way to go carb. or efi sniper...
Your right the chips are a head ace sounds like you have va nice build though I would save yourself some money and a head ace and put a carb on it I've heard good and bad about the efi units but if you have much of a cam they seem to have a hard time learning
@@CCAutoWorks you are absolutely right about that...i have heard and read alot of people having promblems with them efi and i dont have time to call holley and summit and edelbrock and wait on the phone for hours to get some one to help you... and im pretty sure you no what i im talking about..plus it will be less money and less problems
@@thedobermangang3503 the biggest problem is on the efi units is even the people making them don't ha answers alot of the times they will just say give it time it's still learning
Hey how are you I’m running something like this on my obs same carburetor I’m useing all must all the same as u but I’m haven a hard time to get my fuel up to 6psi
Fuel pump is weak or fuel filter is clogged or there is trash in the fuel tank that clogs the sock on the fuel pump after it runs for a few minutes
Im having problems getting my fuel pump to run. I have a 1992 c1500 sport truck that I just installed a 1965 327 sbc. Where do you run the purple/white wire if you have a msd distributor?
With an msd idk really but on a hei you run it to a tach signal wire
Or you can do this images.app.goo.gl/bjN5JDquhYg7vick7
What model fuel regulator are you using and I’d like to see how you plumbed it in.
www.ebay.com/itm/Holley-12-887-Carbureted-By-Pass-Regulator-6-PSI-Black-E-Coat-1-8-NPT-Boost-Ref-/173461623626?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=711-127632-2357-0
I just cut the stock metal lines and slide a rubber fuel hose over and clamped it and the fuel regulator is marked in out and returns out of the bottom
What's up with the service engine soon light. Is it on because of the carb swap?
Yes I just need to pull the bulb out it's on because the computer isn't getting a reading from any of the sensors
Ive got a 3500 Express with a L31 Vortec 350, and the TBI is starting to give me shit. Considering upgrading the fuel delivery, but that trans module is a huge cost compared to going to a big block TBI on an otherwise stock work van. It usually runs fine snd drives fine, tows with no issues, but when its got problems it just dies and takes a while to get cleared up to run again. Might need the fuel lines replaced too, but that spider under the intake is just a bad design. Its less of a problem on the TBI built for the 454, but still a TBI.
What was the total cost to go to virtec heads and run a carb with regulator? I'm definitely not resolved to using a TBI, might go to a 750 cfm carb on a dual plane intake.
If i have to pull the engine its getting a lot more work than just that TBI upgrade. Might get a 6.0 4l80E drivetrain at that point.
6.0 4l80 sounds good but back when I done this I pulled the heads from a junk yard for $40 the vortec summit air gap intake was $200 carb was $320 regulator was $55 air cleaner $25 and hei distributor $60 custom ground roller cam was $200 lifters $80
yes, I don't consider the '96 up Vortec an improvement on the TBI at all...much crappier distributor design, crappy spider injectors and plastic intake, and far more electronics and sensors...
@@dyer2cycle I agree when it's in stock form but the roller block and the vortec heads are a good improvement performance wise
I had my TBI and intake bored and beefed up. Wish I would have went carb and saved some headache
I completely understand that
So do you not need the computer when you put a 350 in a truck? I’ve been thinking about swapping motors, it’d be easy if I didn’t have to worry about the computer lol
If you carb swap it you don't need a computer
Judging by the color of the pickup I'm going to ask what the hell you're doing under the hood of my truck? LOL mean it's the same color and has a manual transmission. LOL I know the vortec heads are supposed to really breathe a lot better. I'm getting ready to rebuild an engine and put in my truck is the reason I'm asking all the questions. Would you recommend going with a Vortec heads on a TBI rebuild covertes to carb? Thanks for the video
Depends if your running a bigger cam and how much money you want to spend
💯💯💯🔥 Yes sir
Salute 🔫🔫 thanks for watching
i hearrd with that 700r4 trans dont you have to get the converter lock controller sense you not using the computer ....
Yes your right at the time I was thinking the 700r4 was like an aod but it's not tci has a vacuum control lock up switch
Man that generation Chevy is a pain to work on and tune for power. Switching to a carb is the right way for sure!
Your 100% right Thank you for watching
@@CCAutoWorks wouldn’t miss it. Good work!
Badass!
I have all those parts laying around from my old 9C1 I’ve LS swappped.
Ahhh what I was looking for. I have an 88.5.7 with SM 465 . I’m so over the TBI and stock dist, but don’t want to lose Cruise control. So you left the harness alone other than DCing the TBI and DIst and the cruise still works? Thanks
Yes all the stock harness is still there and my cruise still works great just make sure you get the right throttle bracket to make it all work
I like to thank you for all the Information on the swap. I have one question the truck have a 4160 transmission what would it take to Install the 700R transmission I know the tps control transmission down shift.
i see you dont have the outlet line on your pressure regulator for the vacuum line i thought u have to have that
The pressure regulator that has a vacuum reference is for when your running boost I believe
Did you have to do anything to keep the AC working?
No you just might have to idle it up a little more so it doesn't die when the compressor kicks on
Did you have to change distributor gear for lt4 hot cam, I'm getting backfire thru carb.
Sounds like your timing is off but I did change my distributor gear out for a brass one because of the roller cam or they have a different material distributor gear that's harder then brass but still softer then the cam it starts with a M
Thank you I will try that.
@@pete4000 the only reason for the gear change is so it wears the dizzy gear and not the cam gear
From what I know, Vortec V8 didn't come out until 96?
So before that it should be no problem with the heads
I used vortec engine when I did my carb swap
Any way you can disable the service engine light ? I am planning a tbi to carb swap.. Thanks
Yeah pull the dash apart and take out the bulb 💡
Works for me ... Thanks Brotha @@CCAutoWorks
Did you have any issues with the cam, and is it flat tappet or roller,?
No issues it's a roller lt4 hotcam
Hopefully you see this and maybe I missed it but I just did this to my 87 suburban... what did you do to get the fuel pump to kick on I'm on that last step and have no fuel?
I watched it again and found what you said and colors of wires... thanks!
There's a purple wire in the factory distributor wires that you hook to the tach port on your hei distributor or you can wire the factory pump relay
images.app.goo.gl/2f3pxuDLruRQ6Kyu7
I have a 700R4 in my suburban then I'm trying to do this too. What all would have to be done for the transmission? Is it just the kickdown cable that I have to worry about?
No you have to wire in a converter lock up tci makes a vacuum switch to lock it up
www.jegs.com/i/American-Autowire/073/500412/10002/-1
Say I don't do this and just shift it manually would that hurt it?
@@rjlittlefield9209 the way I understand it is that it will work as normal as long as your tv cable is set right but the converter won't lock up and it won't get as good as gas mileage because it's not locked but I'm not 100% sure but this is what I've read and heard
I can't get my fuel pumps to work and I have the purple with stripe wire hook to the tach side of the hei
I have heard of it not working on some you can run an ignition wire to the rely behind the cover on the passenger side firewall
images.app.goo.gl/MuXj8EeismFpEqRV6
Without the fuel return with an overheat the fuel pump cause a vehicle to
Yeah your right that's why I always run a return
What if I have a 4l60 transmission
You can still do this with a tps sensor and box but there really expensive
and let me say this part of it not running right have alot to do with my friend that rebuild it ..he mess up it was burning oil one of my spark plugs had oil on it and i took it back out and he redid it put it back it and still got the same problem so hes not going to mess with my engine again had to pay me my money back so now im getting everything done again..
The buddy system doesn't always work out but at least he's giving you your money back but I think even with that it still should have run close to right
Do you think it's the rings or maybe a valve seal and I've even seen an intake gasket not seal and suck oil out of the lifter valley into the intake port from the under side on one or two cylinders
do you have a parts list for this build ???
No but I could probably send links to most of it or the carb swap part anyway
How did the a/c turn out I swapped mine now my ac doesn’t work
That's a good question I knew my a/c didn't work so I have no idea
How did you retain cruise?
Just bought a throttle bracket that holes all three cables throttle,cruise, kickdown if u have an automatic
I carb swapped my 1994 blazer full size, it stalls after about 5 minutes of run time. I have the fuel regulator at 5 psi and an HEI distributor. It always cranks back up tho. Could that be something electrical that I need to fix?
How did u go about hooking your fuel pump up
@@CCAutoWorks it’s the stock fuel pump
@@wyattearp3848 did u wire the relay or did u use the distributor trigger wire to turn pump on
TBI worked great when new..but after trying everything to solve a random misfire on a 30+ year old truck, to no avail, makes me start wanting to just convert it over to a carb..anything with a computer and sensors, even the older and more simplistic stuff, has too many things interacting and effecting each other...much easier to diagnose and repair if everything is simple and independent of each other..ignition system independent of the fuel system, fuel system independent of ignition, so on and so forth...
Very true
Same problem here. 89 4.3. idle stumble, random misfire, ICM failure has gone from once every 2 years to every 2 weeks.
I never had these problems with carbed Chevys.
@@fgoindarkgI have an Iroc Tpi 350, how does wiring a carb swap work. As far as fueling can I just keep the stock ecm and wiring and the stock fuel pump in there and then cut into the stock fuel lines in the engine bay and use fuel pressure hoses to hook up to a regulator and to the carb? What other wiring do I need to worry about Trans wiring, ignition wiring too? What’s the least to make it run. Just need someone with experience to give me tips and general answers 😊

i have been told that 1406 carb that i have my engine is pulling quit a bit of vacunnm the jets needs to be change to the smallest ones .095 and put in the fattest metering rods and put in the heaviest springs that will make a big difference on the fuel..
With that cam your running you probably don't have much vacuum at all so it freaks out the card put a vacuum gauge on it see how much vacuum it makes and put the stepup springs in it for the vacuum it's making but you will probably still have to change the rods and jets to lean it out
