no, not in a hurry.

TBI? The vortec would have an SFI system on it. Is this a conversion?

Then this is not '96 engine if it has the TBI.no. The engine currently has is a shell/block plus internal parts of the 350 vortec and the tbi setup(injectors, heads,intake).
Gotcha....block is 96 vortec but has tbi heads,intake,and injectors on it.
