Tuned port Injection
 

does anyone know if theres a difference in the TPI system from the 305 camaros to the 350 camaros or 350 vette engines?

Well, the 305's use 19# injectors, while the 350's use 24# injectors. The fuel pump is different, and of course the ECM needs to be made aware of which types of injectors you have.

:stupid: those owuld be the only differences...the actual intake manifolds(upper and lower), runners, and throttle body are all identical

The Vette fuel lines are different; they come in at a different location than F-body lines. Also, you will need the corresponding knock sensor and ESC module for a 350 car (or 305, whichever you're swapping between).

fuel pumps are the same for all TPI(305/350) as far as i know

now if you want to get into differences between years of TPIs... that a whole different story. MAF, SD, cold start, maf relays, electronic speedos, etc..

thanks for the input, i want to buy a used 350tpi and rebuild it, for some reason i like the TPI lol, but what i was going ot do was to work on the 305 for the time being getting a holley stealth ram system and maybe redo the exhaust for until i get a REAL job lol, i wanna run true duals, longtubes 2 high flow cats and 2 flowmasters cut off before rear axle
