im just starting to learn the basics, so bare with me. i was wondering, is there any difference between a TPI set up off of a Corvette and a TPI set up off of 350 in a camaro? what are the differences between 305 and 350 TPI's? thanks for all the help guys.

 

The plenum, runners, and intake are the same. The injector size is different between the applications. The 305 uses 19 lb injectors, while the 350 uses 22 lb.

 

Depending on the year one uses a Cold Start Injector. Otherwise, they are the same except for the different fuel injectors 19/22#.

 

Corvette base and fuel rails are not the same as F-body.

- The vette base has a different EGR set-up where is is plumbed externally from the exhaust manifold (since the AL vette heads don't hav ethe crossover) They also have the early style center bolt holes. I'd imagine the early base pre-AL heads is the same though.

- IIRC the vette fuel rails inlet is on the oass side, not the driver's side like an f-body.

Also, the vette runnes have a rough cast appearance while the f-body are smooth (except for late 92 cars that got the leftover vetter runners). No difference in flow or function, but they look different. The rest is the same though.

 

Like stated before, the Vette base has an external EGR port on the back passenger side of the intake, since the Vette L98 heads didn't have EGR passesges.

The fuel rails are different at well.

thanks for clearing that up guys.
