Hi guys!

I would like to know if the intake manifold, throttle body and injectors are the same on the 350 and the 305 TPI?

Thanks!

 

Injectors are different ;19lb for the 305 vs 22lb for 350.
Intake is the same but there are year by year differences.

In any given year they are the same. Aluminum head Corvettes are different because of EGR provisions. The TPI was originally built and sized for the 305 and was used "As is" on the 350 except for the addition of 22 lb injectors for the 350 engine. This was done to save money. The cost of a different part for a 350 could not be justified by the bean counters at GM. The TPI was so superior to the old "crossfire" system on the 350, that the difference in the two systems was startling to say the least. It was hard to say what would have been possible if a higher airflow capacity TPI had been built and used on the 350 HO engines. A lot of our troubles would have been eliminated!
