the major issue will be the injection and flex plate selection.
The flex plate for a 76 should be 28 Oz and the 92 will be 54 Oz.
then i believe there are two different bolt spacings on the C4.
the final issue is number of teeth on the ring gear to suit your starter.
This may sound a lot, but don't despair, my experience so far has shown that flex plates are available for all combinations i have tried. It just a matter of research.
Thanks Jas. I won't be using the EFI, will stay with carb.
Plan on using whole engine from TBird including starter so teeth shouldn't be an issue.
Hope the C4 torque converter bolts up; will be pretty simple if it does
