1966C-10, I've got some pics, unfortunately they are on my old laptop, which doesn't want to network, which also means no DSL. The pics are of a 64 which someone had put a 292. They did a better job than your PO. That 292 had an oil bath air cleaner. My 63 C20 which may have an original 292 has a paper air cleaner. There arn't many differences from a 250, the motor mounts, exhaust manifold - 3 bolts - different entry angle, and possible alternator bracket. You've already mentioned the bypass, which the early 292s had. I've got headers on mine now so Carryall Jerry maybe the best bet right now.
