My apologies to Kevin for totally derailing his disc brake thread and turning it into a discussion on big block exhaust manifolds. I'll move that part of the discussion in that thread to this thread.

No, the big block Chevelles didn't have a special manifold for the solid lifter big blocks, crazy as it seems. Only the B bodies used a special manifold for the solid lifters and on top of that, only on the 65 B body L78 and the 66 B body L72.

Bruce, you do know that B body and A body manifolds don't interchange?
No, I didn't know that. But thinking of it, the one I'm thinking of selling I think is a Corvette casting #. It is straight at the bottom, the 66 425HP has a curve at the bottom (I have a set of the correct ex mans) That makes sense them being different....

Those are the hard to get exhaust manifolds, 827/828 without emissions holes. I have the same set" with" the holes. The one above on the right is for the drivers side, I have one but it goes straight at the bottom. I believe it was used on the Corvettes.
I had bought a set for my Strato Chief 427 conversion but then I found originals so the Dormans went back. But I had no complaints about the Dorman pieces, they looked great and it seems to me the price wasn't all that bad on them.

I'm not sure where you found that but 3994045 is not a Corvette manifold that I can find. All my books say the 66 L72 B body left manifold is the same as big block Corvettes.

I show 3994045 as fitting Impala/Caprice and pickup trucks.
I bought them from a Corvette guy, so I jumped to that conclusion that he said they were off a 74-75. I never checked the # to GM parts, but it seems they will fit some Chevelles and for sure the B body 65-65 cars. There is no "turn down" on the bottom, makes it a little difficult to install the oil filter.
