The 87 will bolt in to the 77 however, the 87 is throttle body fuel injected. You will have to convert the 77 over to except throttle body fuel injection perhaps with parts from a donor truck.
YES they are the same.
Most 1987 models put out around 190 h.p.

YES they are the same.
Oldsmobile used Chevy 305's. 76 350 rocket 77 305 Chevy

Yes. It should bolt right in.
305 or 350 Chevy car or truck 76-79
yes
