Converting a TBI truck to Carburetor And a bunch of other stuff

[@codyboone9490]

I have been looking for a video like this for forever. I got a motor built that was supposed to be capable of 500hp+ but my 2 barrel tbi has been restricting its power to maybe 300. I just have never been able to find someone to fully explain what goes where and how not to ruin my daily. You have saved me man 👍

Glad I could help

just swapped out the v6 in my 89 5spd for a 96 vortec 350 i pulled from a wrecked truck. i put a square bore manifold for vortec heads on it and a carb / hei. best thing i did to that truck. thanks for the videos

[@HarmonGarage]

Yes sir. Thank you for watching

Congrats on 3000 subscribers. Lots of great stuff in this video. If any of your viewers want to change a TBI motor to a carb setup Edelbrock makes an intake for that. Part number is 2104. Some of my customers over the years have asked for a sock style screen to go at the bottom of a carburetor style fuel tank sending unit assembly. I have found that some of the later model fuel injection style fuel screens will fit securely. You have a fantastic KZbin channel! Thanks for your efforts!!

[@HarmonGarage]

That’s buddy

[@LarrySaucier-sq9om]

thanks for theinfo about to do a cam carb swap on my 88 siverado

[@HarmonGarage]

I problem. Glad I could help

[@drought-yo2kn]

After 86 on c10 they changed it to r10/20/30… those engines have tbi if they run on gas. Long story short those tanks have baffles on left and right sides to keep those in-tank fuel ⛽️ pumps primed. Great video for the relay bc there’s not a single video with info on providing power to those fuel pumps.

[@HarmonGarage]

Thank you

[@paulbickmore4523]

I always wondered about how the wiring went if someone wanted to do that change over, great content. Hope your back gets better soon!!!!

[@garygoodwin161]

Real good work on your project trucks and video

[@HarmonGarage]

Thank you

[@RedEyedPatriot]

Before I LS swapped my c10 I took off the quadrajet and went with a Edelbrock Avs2 650cfm 1906. Was really good carb. I had a 84 with a 87 engine that had been carb swapped too.

[@HarmonGarage]

Yes, the edelbrock are really good carbs. I run them alot

[@juniornunley5412]

Lots of great info on that intake conversion. Glad to see how great that water catchment system is working, that will make things a lot better around the shop. Take it easy on that back, been down that road. Enjoyed the video, take care!

[@HarmonGarage]

Thank you Junior. Take care!

[@spymaine89]

Throttle Body Injection TBI (Throttle Body Injection) is a type of fuel injection system used in automotive engines1. It has one or two fuel injectors mounted in a throttle body, delivering fuel into the air above the throttle plates. In a vehicle crash, loose objects can become projectiles, causing TBIs when they collide with a person's head2

[@HarmonGarage]

Ok.

[@gmcnelly2468]

Would like to see you do the tbi to carb conversion on a '93 to '96 with the 4l60e trans.

[@HarmonGarage]

If one comes thru someday I will do it.

Another great video. I know it's easier said than done, but try to get some rest and take care of your back,

[@HarmonGarage]

Thank you Bud.

[@headersandstrings6737]

That couldn’t have been running right with those center bolts being that loose! I would prefer the carb over the tbi anyways!

[@HarmonGarage]

It was running really hot, and rough. Had the wrong style spark plugs in it. Huge vacuum leaks, etc

[@DouglasWestfield-ln8sb]

Could you possibly show us what you did to get fuel from the old lines to the carburetor? I didn't see that anywhere in the video. I know you put in a mechanical fuel pump. Did you have to remove the old fuel pump from the tank or what?

[@HarmonGarage]

There is a video in the rumrunner playlist where I modify a fuel tank in a obs to go to a carb

[@JuanMejia-kl7vp]

So I put a new harness on my truck and would like to delete the old OEM harness and get rid of it since it’s basically junk. Would me going carbureted help me get rid of the rats nest of a harness? The new harness is basically a new body harness but I would need to splice into the new one to run it. Also have a trans controller since I have an 4L60E. So not worried about that either.

[@HarmonGarage]

It would help

[@mattmonteith2175]

I just did 96 to 98 vortec engine swap to TBI

[@HarmonGarage]

That’s cool

[@aliaswizard6963]

I have a 1979 Impala I have a TBI converted over to carb . The guys that done it for me install electric fuel pump just wondering was that necessary? Or could I just keep the OEM fuel pump inside the tank?

[@HarmonGarage]

You could keep the factory one in the tank but you have to run a fuel pressure regulator

[@jaredaaenson9489]

So I have a 95 chevy 350, with a 4l80e transmission, I did a carb swap on it, did all the wiring like you said, got it running. But now it's not wanting to shift right. Skips gears. What am I missing?

[@HarmonGarage]

That’s an electronically controlled transmission. If you switch to carb you have to get a stand alone transmission controller for the trans

[@brick2077]

You can always swap the tranny for a 700 r4

[@FrankOliver-c4p]

No you do not you don't have to buy that stand-alone b******* my truck shifts just fine only thing I replace was my intake manifold put a 650 Holley carb fuel pressure regulator and the rest of the is running off the computer so I don't have a whole lot of timing to play with it's already preset

my cousin is giving me a cast iron 4 barrel intake and Quadrajet freebie! my Question will I have to angle drill the 4 center holes? I am putting on my 88 Scottsdale 5.7 litre tbi? Thanks again for the video.Yelm,WA

[@HarmonGarage]

You can angle drill the center holes but it’s really hard to get them to seal.

[@Agecaraudio1]

So what do you take the fuel pump out the tank ....👀

[@HarmonGarage]

So the mechanical pump doesn’t have to pull fuel thru it

[@joeclark9042]

Love the videos brother I really do you do very good work in I like working on the old Chevys myself but I have a question for you what size is that garage can you tell me that I'd really appreciate you brother thank you

If I was doing this on an 88 with the 700r4 would I just need a new kick down cable for it to work correctly?

You should be able to use the same tv cable.

Your torque converter lock up should still work. If not watch my video on putting a 700r4 in the white squarebody and I show how to hook up the lockup

The intake came from what vehicle the tbi intake boots are different from regular intake

[@HarmonGarage]

This was a non tbi engine. Somebody put an older sbc in the truck with the tbi intake and the bolts being different was most of the problem

[@jerrylewis2423]

Distributor is likely 180 out

Could be

[@johnspencer7291]

doesent this swap have an effect on the 4l60e transmission?

[@HarmonGarage]

This truck had a th350. It had been previously swapped

[@johnallex2344]

What's the best carburetor for 4.3 TBI conversion I was thinking a Rochester two barrel and a HEI is there a good adapter plate that you know of

[@HarmonGarage]

Not to go from tbi to carburetor. But you can buy a carburetor intake to do the swap

[@johnallex2344]

@@HarmonGarage ok thanks I seen the intake didn't want 4 bbl would like it simple and good on gas those electronics give me a lot of problems broke down 4 times

[@jefferylayfield5788]

Did this truck have a TPS on it for the electronic over drive transmission the rest of what you just done is understandable but what is needed to modify for the TPS hook up?

[@HarmonGarage]

This truck did not have a 4l60. I didn’t have to do anything for the trans
