if i wanted to change out the v6 and put a v8 in, what needs to be changed? is it worth it?

What kind of car?

This website is dedicated mostly to 1st Gen Camaros 1967-1969. During those 3 years, no Camaro ever came from the factory with a V6 engine. 6 cylinder engines of that era were Inline designs, not V-shaped.

I'm not sure what year GM introduced the V6s into Camaros?
