hey i did a search but i also want to be sure of what im doing when i do this swap. If i get a 350 TBI and swap out the 305 TBI what will i need to change in the car? will i need a new wiring harness or ECM or anything like that? Also will the stock tranny and rearend from an 84 Z28 305 TBI hold up with a 350 with all modded internals such as cams, pistons, etc. and all stock heads, intake and carb for now, until i get enough money to rebuld the whole thing? thanks alot

 

ecm will work but youll need a new chip, youll need a 350 knock sensor, harness will be fine, and the rear if in good shape should do just fine, thats if your doing a 350 tbi. if going to carb youll need a 3 port fuel pressure regulator, a different distributer, im sure im missing something but im sure someone will pickup where i left off.....good luck
