HI all, I am working of my 1965 442 as some of you have seen in my thread. I have a general question for those Olds Guru's out there and some exhaust questions.
1) Has anyone used a 1966 dash in a 1965? if so how does it fit?

2) What headers seem to fit well when running a 455 in a 1965?

3) When running a 455, with Edelbrock heads, preformer intake, 232/571 cam etc, should I be running 2-1/2 or 3" exhaust?

Thanks
