No 2 Form A Gasket - Best stuff ever. My dad turned me onto it, I've used it for over 45 years. It is my go to gasket sealant, except for fuel related items. Fuel will dissolve it, so remember that the next time you are trying to remove some after disassembly
I just bought 2 77 Chevys both 454 and both 4 speed with granny. I am literally about to make the same vid using both trucks. lol Love your stuff man. Can't wait to see your future vids!
Thank you for the video, I really enjoy watching these types of videos, though I wish there was more small block Chevy videos, those are my personal favorite, just love a SBC :) have a wonderful time!
Thanks! 7:57 You are the only person I have seen address the issue of using the small front and rear gaskets of the intake manifold. It seems weird not to use them, but I guess they are for newer V8 engines. Also Thanks for teh tip on the form-a-gasket. Will certainly do that!
Just about finished the top end rebuild on the 454 in my 74 Vette, new cam, valves/springs, push rods, rockers hope to fire it up in the next week or two and hopefully it fires up as easy as your mean ass truck.
Carlos Aponte Yes 74 was the last year for the 454 in 75 the biggest engine was the L82 350 and below that L48. The 74 454 and 75 350 make around the same HP big block still makes more torque.
I’ve heard many horror stories about these off the shelf “refurb” QJets that all the big retailers sell. Internet lore has it that these QJ’s are assembled with completely random parts with no regard to how it’ll run. You’d have better luck rebuilding an original 454 QJ I think... When I refurbed my ‘75 Camaro to get it driveable, I rebuilt the original QJ and it worked well enough. It would hesitate a bit at 4000+ but did fine as a daily driver. I blame a vacuum leak for the hesitation, not the carb FWIW. I never changed a single part on that carb, and I think it did pretty well considering that... To anybody reading this, DO NOT buy a refurb QJet, rebuild an original and save yourself the money!!!
Great video ! I’m planning on swapping out the stock intake on my 79 and installing an Edelbrock spread bore . My quadrajet works great.. I bought it through Summit. Then headers after that!
Don't suppose you would sell me that choke spring you left on the stock manifold. I just bought a dead horse and am trying to get it drivable.Woud love to try these upgrades some day.
Definitely oval port heads which have been noticed in the previous posts. Either way nice video, i'm still debating on doing a Edelbrock carb or Holley, I'm kind of leading towards Holley for the simplicity design.
If you get an Edelbrock get the AVS series. The basic 750 I used here has an un-fixable lean spot right off idle. Turns out it's an issue with the larger (750 and 850 cfm) Performer carbs that Edelbrock won't admit exists, but fixed with the AVS series.
Rookie question, what kit did you buy for the electric choke conversion? Or did it come with the carb? I just had the GMC dealership rebuild my stock qjet and wanna do an electric choke conversion. Btw I borrowed your intake part number to save me the trouble of doing incorrect research on my 79 suburban 454.
My 75 gmc has the same choke setup. I've rebuild the quadrajet and it runs great except when the choke is on, it'll idle fine but trying to move until the choke closes results in a loss of power and chugging. Especially noticeable up hill and starting out. I'm gonna check the spring and make sure it's not broke.
Your problem was going with an Autozone reman. I didn’t read through the comments but I hope everyone that has a Q-jet listens real good to this. The rebuilding houses for the units Autozone/Advance/Napa are building absolute junk. Anyone that has been into one of those carbs and knows anything about them knows that the metering rods and jets are unique to that particular carb. When these rebuilding houses get ahold of these carbs parts are mixed all around so you have a Frankenstein that is completely mismatched in parts, has no way to accurately meter a fuel mixture and that’s just the beginning of the problems with those things. If you have a complete non molested carb that is appropriate for your application have a competent rebuilder build it. Don’t be a victim of one of those POS carbs.
I figured that out years ago and found a specialty place that just does Q-Jets and has been a great carb. I needed to get a M4ME for a engine swap with a L69 305 I had in another car. It works like a charm and ready to do quick adjustments.
Your motor looks like mine. Old and rusty. I am getting ready to do the same thing to my SBC 350. Edelbrock EPS intake, upgrade to HEI from points, Haven't decided on what carburetor yet. Holly or Edelbrock. Everyone has an opinion as to which is better. I have a quadrajet now. Let me know if you are happy with what you used. I would appreciate the input. Thanks John
FI tech won't give things to a channel called "Fuel Injection sucks!" Haha. I just found your channel today. I have a '78 too. Also I saw you had the vacuum advance plugged into the ported vacuum side of the carb, shouldn't it be on the other side that is full manifold vacuum?
@@FuelInjectionSucks And I always run it to the manifold vacuum, which is how it was always done before the government and the companies tried to improve emissions by running them to the ported side.
750 cfm is to big for stock heads....will actually lose power.....650 is max for stock usually. And ty for not buying a Holly....lol. Youll love that carb
I went with what was "supposed" to be in the motor in that truck. After posting the video I considered those were actually oval ports, and that someone was probably in the motor before, or swapped the whole motor from something else.
I put an Edelbrock carburetor on my 307 Oldsmobile the car ran great but it didn’t want to shift I didn’t change the distributor from the computer control dist and my computer is still hooked up was this the problem or is it something else I didn’t do check out my video towards the end if u Edelbrock 1406 up running fail...... 86 cutlass 4 door th-cam.com/video/ZysGVxbRGoc/w-d-xo.html
No, that's not the reason. You most likely do not have the TV cable set up properly if you have a 200r4 or 700r4 transmission. If you have a Th350/Th200 then you most likely don't have the vacuum line from the modulator hooked up, or to the wrong port.
Fuel injection absolutely sucks. And it's not even necessary. People don't understand that the only way your new shiny piece of crap gets such great mileage is the gearing, not that fancy, complicated, over priced fuel injection system.
Hi, I don't believe your BBC heads are the peanut port! I have peanut port heads on my 84 1 ton dually and your heads are diffintly not peanut port you have the regular oval port heads.
Thread tape works the best and it is and give you no mess to deal with but not knowing anything like you you probably forgot to and don't know anything about it
Also, you may know more about teflon tape than I do, but I have a better grasp of basic grammar and sentence structure. Let me fix this for you; "Thread tape works the best. It gives you no mess to deal with. But, yourself, not knowing anything, probably forgot that, and do not know anything about it."
Your inability to rebuild carburetors so you went with the third best carburetor on the market Hollywood be the first quadrajets the second but obviously you turn it upside down and got to a little stainless steel ball and they're stuck in a position where it's not supposed to be so you didn't know what to do to fix it watching your video you don't know much about cylinder heads which I probably told you about that and another statement on your video I think it's really funny
I didn't use a Holley because I prefer the way the choke works on Edelbrocks. I'm not going for high performance, just drivability, and from my experience Edelbrocks run better on stock-ish motors that don't have a large cam. Feel free to pass on your vast knowledge that is far superior to mine to your 5 subscribers though.

Great job. I have a 454 in my K30. An intake and cam swap is on my list. Thanks for the detailed install.
Thanks for doing Gods work here. Lol! Great site and I always learn something new, keep it up and hope the new business is going good.
Probably my favorite truck that you own to be honest.

Great video, watched quite a few others and yours was the simplest and also explained how to mark the distributor.. Thanks again for the video.
That time you install new parts and fires right up... feels good.

Edelbrock's installation instructions say not to use the cork or rubber gaskets, but rather to use a 1/4" bead of RTV, exactly as done in this video.
Man! Looks almost like my truck! Same carb too. Great video
Just about finished the top end rebuild on the 454 in my 74 Vette, new cam, valves/springs, push rods, rockers hope to fire it up in the next week or two and hopefully it fires up as easy as your mean ass truck.
Derek Joon was the 454 still a factory option for Vettes in 1974?
Carlos Aponte Yes 74 was the last year for the 454 in 75 the biggest engine was the L82 350 and below that L48. The 74 454 and 75 350 make around the same HP big block still makes more torque.
+Derek Joon 454 definitely responds to modifications better than a 350.
I love Q-JETS! Built lots of them! Especially the CCC Q-jets! I know, I am OCD to the max and live in a straight jacket!
About time, mr. I'm not modifying it its staying all stock.. Time for headers and a cam.

Sounds better than before, looks awesome with the camper too.
I like you're truck I got an 85 k10 with a 305 they don't make like that no more !!!
Cool truck. I almost have the same truck. It’s a 78 Chevy camper special with a 350.
sounds GOOOOOOOOD!
Nice work sir
I used that say Q jet for life.... but edelbrock is far easier out of the box, hands down
Looks like that Qjet was for an Olds
sound good...good work bro...💯
If that engine has 781 heads, those are NOT peanut ports
Did you need to change anything to hook up the throttle cable?
What are the things called that hold the glass fuses in
Don't suppose you would sell me that choke spring you left on the stock manifold. I just bought a dead horse and am trying to get it drivable.Woud love to try these upgrades some day.
Not sure if TBI is the way to go, I guess port injection would work much better with the lower length the fuel has to travel.
Inline 6's chevy had were blue flame 6. The color is close to that
The choke wire should really be hooked to the alternator so it doesn't get power until the vehicle is actually running.
The alternator is always hot from the charge wire. The other two wires also turn on with the key, same as the point I wired it to.
Or fuse box

Turbo truck progress?
That RV thing makes the truck look tacky
maybe so but when a storm pops up out of nowhere and you're tent camping, you're really appreciative when your buddy has one
You can run the choke wire off the alternator
What does that do? I'm love old American old school trucks. Just learning how to work on them.
doesnt matter where you pull power. what DOES matter is that you verify with dvom that it is getting full 12v.
Did the factory quadrajet throttle bracket work? I saw it painted on the bench. Thanks.
Yes, just had to redrill the holes.
@@FuelInjectionSucks thank you
So I also broke my brake booster vacuum line, how were you able to rig it up to fix it?
Brake line and rubber hose.
What happened to the turbo truck
My 75 gmc has the same choke setup.

Just use a manual pull choke (cable).

Is the carburetor, 1406
Cool Truck Man , Just a Question why use Edelbrock Carb and not a Holley ?
In my experience Edelbrocks are better suited to stock engines.
Thanks
Holley sucks edelbrock is just a carter afb I'm a q jet man

That made her pretty
did u need a regulator with the edelbrock?
I've never had to use one when using stock mechanical pumps. Plus this pump is a factory return style one.

750 cfm is to big for stock heads....will actually lose power.....650 is max for stock usually. And ty for not buying a Holly....lol. Youll love that carb
Stock Q-jets are 750 & 800cfm. That is a bigblock Chevy, not a 350.
CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456. do some math..
A 750 is not too big for this motor.
@@72troy455 yes, but its also a spread bore.....look at the size of the primary's. Secondary's dont fully kick in till peak rpm
Those are not peanut Port heads those are regular oval Port heads I'm sorry that you were misinformed. Porter 1/2 the size of a regular oval port
I went with what was "supposed" to be in the motor in that truck. After posting the video I considered those were actually oval ports, and that someone was probably in the motor before, or swapped the whole motor from something else.
Yep, those definitely ain't peanut heads. Probably 781s or 049s. Peanut port heads came out in the 80s.
