Can I run a 454 Throttle body on a 350?
I'm building a 350 with vortec heads, a bigger cam, and a air gap intake. Can I put a 454 throttle body on it for more cfm?

Yes but you need an adapter plate. The bolt pattern is different because the TBI is larger. A BBC TBI will not directly bolt onto a SBC intake manifold.

Boat engines, including 4.3s ran the 454 TBI on them.
