were all tuned port intakes identical

for example the 305 the 350 and the 350 corvette
were the tpi hardware all the same with the exception of injectors? oh and what about the computer?

my main concern is the actual tpi hardware (intake, runners.....)

 

I believe earlier TPIs were setup with a 9th injector. Also corvette heads are aluminum and may have a sensor or 2 more like the oil temp sensor.

 

i know atleast the 305 and 350 are the same... because the runners are really limiting the 350, because they were designed for the 305

 

Until '89 the intakes had provisions for a cold start injector, as mentioned above. The 305 and 350 computers are different. And I know that '85 vette computers were unique to that year, but I think they may be the same as 350 F Bodies from then on. This is with the exception of all the speed density computers.
