350 TBI the have the same parts as 454 TBI?

[1987_chevy_]

So as of right now I am building a 383 stroker and planning on running the TBI system! I have bought a 454 TBI that I plan on using. The only problem is the the piece that holds the injector pods into place is cracked. Someone installed a injector spacer and must have tighten it to much and cracked it! I have a 350 TBI also. Could I just take the injector pod off the 350 TBI and swap it onto the 454 TBI also switching everything inside over (spring and injectors)? Are the injector pods on a 350 TBI the same as a 454 TBI?

Don't know if you know this, but TBI systems rely on vacuum being in a very specific range. I would opt for aftermarket or go carb'd.

I can't answer your question, but here's a place to start if you need a new one.

I am aware of this, the engine was specifically built to run a throttle body assembly.

I've been reading on this. I think what you're wanting to do will work. I would just try it and see. The injectors flow differently, but the pods and the little stand are the same as far as I can tell.

I'll agree, there seem to be a lot of shared parts. The tbi castings look very much the same, though I haven't tried the swap from 454 to 350 myself. There are a few year to year differences I've noticed with some of the sensors though, but shouldn't really effect the breakage you found.
