anyone familiar w/90* v6s, please help? i've been doing some research, so maybe stuff won't make me look like a total fool...
back in the day, the 305 and 350 were externally identical. you could put 350 heads on a 305 and whatever not. nowadays, the 3.8 and 4.3 are somewhat brothers to their cousins the 305 and 350. the 3.8 has the same bore/stroke as the 305, and the 4.3 the same at the 350. it would be obvious that the 4.3 heads would flow better than the 3.8 heads. GM parts direct's performance parts states a lot of parts available for 90* v6s, which is what the 3.8 and 4.3 are. however, they don't really specify an engine displacement most the time. i'm curious as to know, are 3.8 and 4.3 parts interchangable? flame on, and if i'm right, thx for any advice

Re: anyone familiar w/90* v6s, please help? No, not at all similar.
4.3 are Chevy motors, similar to small block motor in every way..
3.8 are Buick based (3800 etc)
