currently my sivlerado has a 4.3L in it, I got a 5.3L motor I'd like to drop in, unfortunately this new motor has the electronic controlled TB, is this going to be a problem?

Can I switch the electronic to a cable controlled?

etc..


thanks

 

I don't see why you couldn't switch it to cable controlled as long as you had an '02 throttle body. maybe someone else knows better, but i bet it would work.

 

Wow, your in for a job. A V6 to LS1 swap. You need alot of little stuff to make it work. You will need a PCM for a LS1, wiring harness, motor mounts, new fan shroud or e-fans, and yes you can throw on a cable controlled TB.

Why not just give the 4.3 a performance boost? I had a red 01' just like yours with the 4.3, and did some mods to it. It was running 9.7s in the 1/8, and 15.1s in the 1/4. I wish i would have pushed it to see what it could have done.

 

I think he wants the big bad V8 rumble

 

Thats why i got rid of my V6 too. Now i have ALOT of performance stuff for stuff left over from it, that wont work on the V8 truck.
