on my tbi i did the change from 305 to 350 saw some gains but not what you would consider gains. and now have access to a 91 wrecked GTA. i get everything from motor and tranny and harnes fuels setup everything but the fuel pump.TPIS is going to burn me a chip for 100.00 which aint bad. but will this change over easly. im also buying vortec heads and the LT-4 Hotcam for this setup. anyone got any ideas on what i need. this 305 HO inthe GTA has Breand new GM injectors, i know cause i help installed them.this motor is nice only has 80,469original miles and the TPI behind my 5Speed would be nice. if anyone can give advice plse do.

 

since you have a parts car it should be easy but take your time.. thats good that you got a 91 gta tpi car because that would have speed density.. good luck.
