Which exhaust manifold
I have a 69 427-390hp 4 speed.I am replacing the Hooker sidepipes with the original factory sidepipes and need a pair of exhaust manifolds,part #'s 3880828 & 3880827.I have noticed that they can come with and without smog holes.Which is factory correct for my car??

With smog holes is correct for all '69s. The same casting numbers w/o holes will work, but are highly desirable. I have a pair from 1966 w/o holes, both need repair (one mounting ear on one, and the tailpipe flange on the other).
Mine's a '69 too, and I figured out that Bubba had gotten earlier manifolds because the smog pump is long gone.
I've gotten some headers, so these manifolds can go to sale/trade.
