In the video, we show how to convert a throttle body injection to a carburetor on this squarebody C10. While most people convert to TBI, we take a step back to our roots to eliminate these premative version of fuel injection.
I got lucky with the TBI on my OG 305 in my '87 swb. It was a fairly rough truck when I bought it a few years back. But after a basic gasket rebuild, and replacing the sloppy distributor with another from a junkyard, she fired right up and ran smooth. I'm usually a carb guy. But I'm diggin' not having to pump the gas and mess with a choke and sit there and baby sit it as it warms up. 😎
I've had great luck with some TBI units and some that have fought me to the end! When running correctly a TBI is pretty sweet! But on this one I believe the throttle shaft was worn out causing air to leak as well as something funny with the ECU. And to be honest I thought it would make some decent content, potentially helping some other guys wanted to go down this route.
@@BestDamnShopAround Yeah, that's why I say "lucky" when it comes to my TBI. (Though I expect it'll start giving me issues any day now. 😉) It seems most don't work well and even after you fire the parts cannon at it, it still fights you. So I don't blame anyone for carb-converting it.
12:50 I have rigged up a few throttle cable mounts, and THIS is one of the best I've seen!! ... and YES save those odd ball cut outs, it takes forever to make them by hand!
I am old school die hard Carb guy but the TBI system when running good is bullet proof and will run a long time. Watched the video No Nonsense that travels all over the United states with his Girl Freind picked up a 2500 Suburban I think it was a 89 in Vegas it sat for years had TBI Chris got it running did basic over haul to get it running drove it from Vegas to Penn and averaged 18 miles to the gallon . What full size Suburban gets freaking 18 miles to the gallon with old dirty injectors and probably a worn out throttle body? I was blown away I figured 12 would be max. If you did a bushing kit and rebuilt the throttle body and put in new injectors it would run good and never let you down . Love TBI good cold starts and excellent MPG and simple cant ask for anything better than that
You're right, when they work correctly they're great! This particular one didn't run well and instead of investing time and money and rebuilding it I decided to go with a carburetor with the future plans of removing this drive train and putting it in an older style hot rod which would make it even harder to have TBI. 18 MPG and a 2500 suburban is very impressive!
@@BestDamnShopAround . Chris was blown away too with the 18 MPG it was jaw dropping for me. If you wanted to you could jerk the harness and install the ECM go through the TBI and have that 18 mpg with your hot rod. But I get the jest of Old School and go carb
Yeah I had started to get issue with my tbi and timing retarted so fixed the timing replace ignition coil and new cap and rotor and also put English flush to clear up and clean up and wtv else it could do to clean the injectiors seems to done the trick for my truck still has lil something I can tell but last thing I know of needing to replace is my lifters and cams and likely push rods and all those components
Did you figure out what was wrong with yours or did you just carb swap aswell I can't get mine to run right and have changed everything besides putting a carb on
I changed intake ,distributor, and carb.. it started right up.. I took computer and all out of vehicle.? Customer was very happy and still driving truck..
Awesome vid. Answered all questions I had about my build. Only thing I'm concerned about is, will the stock fuel pump keep up with a 375 hp 350 with a 750 carb?

@@BestDamnShopAround had issues with my 92 k1500 changed every sensor, dizzy, coil, fuel pump couldnt get it running good for nothing so I did the swap had a tough time making it run turned out to be the oil pressure sensor it is also a safety switch for fuel pump once I changed it fuel pump runs as it should, my issue I was following other peoples wiring for distributor all I used is the coil wires white and red white for tach. I tried the purple wire didnt work
Thanks for making his video!! My 1994 Chev Step Van dies ne day, I put it in my mechnica, and they spent some time with it, and let me know it's not going to be economical to get it going, (they know my style and budget) My van is supposed t e throttle body, but they impleud it was full fuel injection. If it IS??? Does anyone know?? If it is full fuel injection can it be converted to carburetor in this same manner???
Yes, it should be fuel injected. I personally never done a carburetor conversion on a step van but it should be the same basic process as a pickup truck, it should share the same 350 cubic inch small block
I'm about to comvert my 94 Chevy Cheyenne today but what I didn't realize was that my transmission has wiring that goes directly to the electrical computer box... its a 2x2 3500 ... What would be the alternative for transmission wiring?
Curious, when u say ur going to clean up the wiring later, how exactly r u going to do it? Are u going to follow the wires for the tbi stuff back to the ecu and snip em there?
Great video! I have a 2001 s10 4.3. No one can get it to start. A little either and it runs great from then on. New computer and a bunch of other stuff! Tired of fooling with it
Thank you! I know that they made a carburetor version of the 4.3 that came in some Marine applications. Might want to look into that, imagine an intake manifold will be the hardest part on that truck
Which Transmission do you have. If it's the 700R4 like my 89 K2500 is what do I do with the TPS. I know I need to adjust the TV Cable on the Trans but the TPS has me stumped. Do I just not use the TPS or do I have to hook it up to the Carb.
Multi port is definitely better but out of the budget for this project. I've had pretty good luck with modern fuel in carburetor vehicles, but I love in Georgia and I believe we have pretty good fuel here.
