350 to 454 TBI swap

[Frogg89]

I have a post in the wanted for a TBI because I broke my housing. Does anyone know if I could use a 454 TBI? Would it mess up my computer or anything like that?

Thanks, Ken /forums/images/graemlins/k5.gif

well the bores are bigger, and if u use the 454 injectors it would probably flood your engine out.

Swap out your injectors and regulator and use the 454 body, it should flow around 670cfm, just like the Holley unit but at a lot less cost.

There have been several threads about getting the adjustments right after the swap but it is well worth it from everything I've read. I keep my eyes peeled for them everytime I'm at a slavage yard, but most of the time they have already been pulled.
