I really like this comment mate. I have a business in high performance automotive and everyone now thinks unless you have 1000hp with a stock motor your no good. People dont understand simple is ok and everything takes time to get right
You should keep an eye for some used vortec heads and intake manifold on Craigslist or go to a salvage yard and pull some yourself. They will wake that truck up a bit.
riley galloway I was thinking the same thing. Vortec heads aren’t the greatest in the world, but on a shoe string budget they have some good flow for a stock head.
It will also skyrocket the compression ratio. Vortec heads have much smaller cc chambers. The large chamber heads on this are probably what's keeping it (almost) right at 10lbs. It would take alot more than just slapping some vortec heads on there.
Vortecs seats like to crack between the valves, you can get fuelie 2.02's pretty cheap now, and it doesnt take much work to get the 25 hp extra back that the vortecs make. Easiest 25 hp gain is stick your finger in the roof of the exhaust port where the header bolts on. Where you feel that lump, grind it out. Thats an old Hot Rod magazine trick that was 25 hp on the dyno. If you do some reading its not hard to get another 25 hp on top of that 25. Try and find the 462 castings.
Seems pretty accurate if it's a true stock 350 was prob only rated at around 200 at flywheel so prob hitting around 360 at flywheel now with 9lbs seems dead on, but a stock 350 bottom end will handle more then a person thinks, I had a stock tbi motor just better head gaskets, bolts and 1.6 rockers, with a blow threw carb and a rear mount 70mm and it went 12.20s @ 114 in a 90s sw @ 15lbs, No idea hp guessed 500ish with diesel torque but it ran well..
I'm glad to see u finished and went thru with this project, I remember seeing ur unboxing video way back , nice to see u got it done , but a nice turbo carb would be nice and go for some more power later .keep it up
Its a bad o-ring on the needle valve when it still has fuel almost all the way shut, and floods when u slightly adjust it off bottom, assuming your float tab is set correctly
You will get it lined out. I have a 83c10 that I swapped a 454 then turbo. I have a blow through carb. It was a stock Holley 750 that I made work with blow through.

It actually isn't necessary on a blow thru carb set up. When the compressed air hits the atomizing fuel in the carb temp drop like crazy, literally 100 degrees plus.

For the frame confinement’s I was thinking either a supercharger, or a procharger would’ve been the better option. I know the eBay turbo kit was probably an experiment, but with money and time spent there would’ve been better performance. I’m not one who likes chomping bits out of the frame unless it’s absolutely necessary, and doubling up what I took out.
Add some runner length to your pipe work. This will help cool the charge and increase torque. That mechanical fuel pump will never keep up with the engine on any 1/4 mile pulls. And lastly, this may be crazy... but what if you installed all that turbo kit on the driver side on the bay. (Obvious run a smaller brake booster or even a street rod booster under the floorboard...and if you had a rack & pinion it would be easy as pie). I bet money that the Japanese techs read the blueprint backwards.
Blow through setups with a carburatuer are insanely hard to dial in...good job though i give you guys credit....not everyone can afford a brand new everything...check the fuel pressure when your at the top of the power curve
I had the same problem until i got rid of that carb hat style and went with a more smoother transition type of hat, the H.P went up high too after that..
Could you try a draw through setup? Ive never turbocharged a vehicle but i figure you could have saved money using a draw through setup and it might help atomize the fuel better, no?
I did very similar with my 1976 bonanza chevy c10 but not me i had a close friend and his brother work on my build truck for about 2 years but they got it down to perfection...its more for the low rpms but somehow i have 3 times more range in my rpms now and of course alot more power but my point is turbo and a strong 350 motor will make some serious donkeypower.....stock transmission and stock height ...dyno is on my 2 do list of many ...love the video....
The carbs have come a long way, but they're still tricky when used with boost . I suppose you could run it inside a box like I did with my R22 Toyota engine once .

On paper , if you put the whole carb in a pressurized box , it’ll work fine. No doubt some things will need mods though. The linkages and shit are a hassle I guess. Didn’t someone make a supercharger kit where the whole carb was in a box that bolts to the intake ? Coulda swore I saw pics of one years ago in a magazine ad.
@@FuelInjectionSucks how is the 9000 hp RV going 16s in the quarter ha ha ha ha ha ha ha just cause it has a China turbo on it doesn't mean it's fast ha ha ha ha ha ha
I checked out your channel to see a real car, but there was just a purple icon of your missing avatar and 8 subscribers. Disappointed, I thought I'd see some real muscle.
Funny to think if you throw a 3/4 cam in it with some 2.02 heads and upgrade intake she’lll probbaly make the same if not more power but naturally aspirated and way cheaper
Looks like a TBI era V8. That is what mine is (1994) Mine makes 220 HP stock. Bone stock with a turbo is maybe 250 hp-ish. I agree that FI sucks, but with a turbo FI is the way to go. If you are going to put a carb on it then you should extend that carburetor hood to enclose the entire carburetor to equalize pressure inside and out of the carb, and then dial your fuel pressure up above your boost pressure. Ideally, fuel pressure should increase as your boost builds. Stock carb fuel pressure is around 6-8 pounds, and you are running 9 lbs of boost... do you see a problem here? There are special carbs for turbo systems that will cost you more than your entire project if you want to just keep throwing money at it, but better to do some research, and replace the correct parts with parts that will work together toward your goal. Much easier on the old carb technology, and you MAY get 300HP. You are trying to overcome crappy heads, replacing the heads with vortec heads and the cam with bit stronger cam might get you 500 HP eventually with some other mods... basically, you can't just throw a spiked collar on a beagle, and expect to turn it into a Rottweiler. Sorry to bring the bad news. I'll sub the channel and give you a thumb up for having heart, and for tackling a tough project! :)
Replace the O rings on the needle valves, or better yet get the high flow needle valves with stainless needle and seats. That solved my flooding problem. Oh and get rid of the power valve and jet up the rears 8 - 10 sizes, this will eliminate another variable in the tuning.
You need to find an old school tuner. The first and simplest thing you do not to waste a day(or weeks in this case) is a rebuild kit on the carb. That will include two new float valves and all the gaskets. Start with open sight plugs. Scrap the $2 plugs and start over. I would also start with a plug for the power valves, a set of different accelerator ramps, bigger nossels if needed and a afr gauge is a must with the turbo. Get lean and get a new motor. Start rich and low(or no(disconnect the turbo for now)) boost till proper afr is achieved.
you'd be better off with a 402 big block. set of cheap headers, intake, lopey cam. it'd make more power and torque than that setup any day. on the other hand, go with a procharger.
I was going to suggest a Holley EFI, then I saw your channel’s name. I commend you on your efforts. This might be a really dumb suggestion, but have you considered a 2 barrel like is run on dirt cars?
Chase G. he's running a boost-referenced mechanical fuel pump (vacuum hose from the intake is run to a port put on the non-fuel side of the fuel pump diaphragm)
Good stuff! Man you get some meat head comments. Guessing you started with the hanger 18 mods on the Holley and curious what kind of torque #’s did it make.
The carb has to be set up for boost- you cant just send gobs of air through it. Probably pressurising the bowls. Also have to have a variable rate fuel delivery system under boost - 4>5psi constant isn't gonna cut it. 1:1 boost to fuel.
you'd expect a stock modern ls type engine to make that kind of power nowadays is that a 305 or a 350 ? wat kind of heads does i has (smog era?) heared some raves about stock iron vortec heads for the old style small blocks , doesnt cost a lot but adds decent power over the older heads
I've got a '74 k20, nothing special about it at all but I'd drive these old trucks and fix them all day over something new, idc if someone will walk all over me with an LS, hell I have one but come on these are just cool
Is the carb a turbo/supercharger specific? That may be your problem. if the carb is designed for NA applications, then the added boost will send the wrong signals and possibly cause your flooding issues
Are they hard to install? I don't know my ass from a hole in the ground when it comes to carbs and they seem so finicky. Anyways I've been thinking of getting something like that for my old 454 that's in my 74 c10
Is this the gt45 kit? If so did you have any issues with anything? And what else did you do to the motor? I have a 74 C10 and someone newr me is selling the kit for super cheap

make sure the o ring seal on the seat assembly its self isn't bad. I've seen them harden up and fuel seep past the seat and flood out.
Nothing wrong with this setup. Especially considering your probably doubled the the stock output with only 8psi. Good job, awesome build

The carb has to be set up for boost- you cant just send gobs of air through it. Probably pressurising the bowls. Also have to have a variable rate fuel delivery system under boost - 4>5psi constant isn't gonna cut it. 1:1 boost to fuel.
Yup, have both.
you'd expect a stock modern ls type engine to make that kind of power nowadays
is that a 305 or a 350 ?
wat kind of heads does i has (smog era?) heared some raves about stock iron vortec heads for the old style small blocks , doesnt cost a lot but adds decent power over the older heads
It's a smog headed 350. I have Vortecs on my Chevelle 350 and it makes more power than this NA.
I've got a '74 k20, nothing special about it at all but I'd drive these old trucks and fix them all day over something new, idc if someone will walk all over me with an LS, hell I have one but come on these are just cool
You have more vids on this build, I'm wanting to do the same thing, same year truck, bad as*
Looks like carburetors suck this time.
ive seen naturally aspirated 305's put out that much power...chuck the turbo or get an efi set up on there that can take being blown into
stickloaf more like file 13 the turbo and run something other than a junkyard carb.
Is the carb a turbo/supercharger specific? That may be your problem. if the carb is designed for NA applications, then the added boost will send the wrong signals and possibly cause your flooding issues
Modified for blow through using Hanger18 mods.
Put a sniper efi on it you will love it.. Best 1200 i ever spent..
Are they hard to install? I don't know my ass from a hole in the ground when it comes to carbs and they seem so finicky. Anyways I've been thinking of getting something like that for my old 454 that's in my 74 c10
Little bit bigger cam and vortec heads should get u AT least 500. If you make 250-300 hp n/a then @15 psi it should make 500-600
You don't run big cam with forced air
Low compression pistons and turbo grind cam
and this is when fuel injection is mmmmmmmmmmmmk
Not really.
@@Shade_tree_garage01 yes,really.i bet this isnt a proper blow through carb either,just a jury rigged pos
Is this the gt45 kit? If so did you have any issues with anything? And what else did you do to the motor? I have a 74 C10 and someone newr me is selling the kit for super cheap
Had to modify nearly every aspect of the kit. Nothing fit. Engine is a bone stock smogger with cam and valve springs.
Needs a intercooler!
badass!!!! ima try that on my 350💪😎
Time for fuel injection. Sounds like it had a dead cylinder too...
did u put electric fuel pump or kept the manual one on?
How my whp did you end up making i wanna buy one!!!
change that fuel pressure gauge the liquid one's read less pressure if they are hot.
it should have made 500hp because it's a turbo V8
