I need to know if a 4.3 from a 1993 chevy C1500 will bolt to the tranny in a 1994 GMC with a 4.3. Both are automatic,2WD. I think the '94 may have Vortech 4.3 thats comming out, the '93 is not. Are there any other problems I would encounter that I should know about?

Welcome to AF
You should be ok on transmission end.
But the PCM wiring may be didfferent.
Are both of the TBI engines?

Yes, both TBI.

They should swap out good.
Good Luck.
