Hello everyone,
I know 305 to 350 swaps have been covered a million times but I wanted to cover my exact situation. I currently am running a 305 TPI in my 88 Firebird (with 700r4 automatic). I am probably going to purchase a longblock L98 350 TPI that came out of a 92 camaro. Since the longblock will not have the intake etc. I am planning to just use the TPI manifold and TPI system off my current 88 305 TPI motor. I know I will need to switch the following:

1. Get a 350 chip/prom
2. Get a 350 ESC
3. Get a 350 Knock Sensor

My question is whether the 92 motor will present another other changes? I know after 89 the TPI system changed;however if I am just swapping in the heads and block from the 92 TPI system should the 88 TPI system bolt right up to the 92 longblock?? Specifically will the intake manifold from my 88 TPI setup bolt right up? Anything else I am missing guys???

THANKS

 

The only thing I see missing is the proper 22lb/hr injectors. Otherwise, I think your bases are covered.

 

You don't necessarily need a esc, if your still has the pn or three letters on it you can post it for identification.

 

Yeah I forgot to list the injectors. And ill get the number off the esc. So there for sure should be no differences in an 88 305 intake manifold bolting up to a 92 350 block right?

 

no problem with the intake
