Skyark. Both V6 231cu. in.? I need my engine rebuilt but its gonna be cheaper if I buy another engine. They look the same, same 231 cu. inches and are both V6. The engine is a Buick made engine. Would it work for my 77 Skylark or no?
 
Believe both cars have computers.Not sure if 86 engine sensors can be read by older generation computer in the 77.If both motors are fuel injected,probably not workable with out putting money in to system.May be cheaper to find a good 86 motor.
 
This is a tough one, because GM used engines from everything from time to time and had a big lawsuit over it. Generally, Buick is all by itself in GM. Check with a reliable autowrecker in your area, as they have substitution books that give the right info. Anything on here is a guess.
