I am swapping a 350 from a L98 into my 89 RS. I have a LT4 cam in it, headers, exhaust, and a K&N. Should the 350 truck's Throttle body and injectors be enough to feed it?

I want to swap to tuned port in the close future, but I need my car done.

 

I'm doing basically the same swap as you in my car. I plan on going with the 65# injectors from the caprice 9C1's because they had basically an L98 with TBI from the factory, so that would be your closest match. Then you can get the ANLU prom from that 9C1 and that's a good base to program off of. The truck injectors are 55pph by the way, so they'd probably work too I'd assume but 65pph would be the best way to go I think.

 

Thats.....a good damn Idea.

Does it retain the VATS too? I know the trucks dont.

 

No, it doesn't retain the VATS as far as I know, but if you can get a hold of some prom burning equipment you can re-enable it I believe or possibly you could send your chip to some of the hot shot prom burners on this board and they could re-enable it for you, I was actually trying to think about the same thing because I would like to retain the VATS.

 

I found the stuff I needed and it is arriving Tuesday.
