Ok boys, I'm finally doing it. I'm pulling the 350 out of my boat this weekend and going to put it into my 91 bird this weekend. I wanna make sure that it is adequetly feed. I have a Perfomer RPM on it now which sits upon a set of Vortec heads and wanna put a 454 TBI on. I need to know what year applications I can use when I try to track on down. And I'll probably end up getting the whole unit, injectors and all cause that's how the junk yards around here sell them. So will I be able to use the 454 injectors or will i have to find 350 injectors? Thanks for the help.

We need a little more info. about your 350 (heads, cam, etc.) you probably won't need a 454 TB or injectors. The stock TBI unit can be made to flow just fine on a 350 with some tweaking. Depending on your set up, you will need 55# or 65# injectors. An adjustable FPR is imperative, especially if you don't plan on burning your own chips.

well like I said, the heads are Vortecs witch means 1.94/1.60 valves. The cam will be around 262-268 degress with about .460-.480 lift(haven't picked out an exact one yet. But I seriously doubt that I stock TBI even with mods will be able to keep up with a 350's needs, especially with that cam. So I just need years of applications for a 454 TBI.

 

Just call a friendly bone-yard and the guy can give you the exact apps...
