I am new to this forum so I most likely will not be of any help in answering much of anything. Enough said.
For those of you that actually are knowledgeable I could really use your knowledge.
I have a complete TPI system (wiring, ecu, etc.) after looking up the #’s I think it is out of a 1985 Camaro.
Manifold #14081005
Plenum #14081006
TPI ECU #01226870
Throttle Body #17075921
It does have the 9th injector for cold starts.
I basically want to build a factory 5.7L with using the TPI I have.
My question is what year motors will TPI bolt up to?
I have been told so many different things from any 350 from 1971 to 1988 to only a 1985 motor will work with cast-iron heads.
All I do know for sure is I have to use cast-iron heads and change out the injectors for a 350.
Any help/knowledge would be great and greatly appreciated.

Thanks
