Well, seems like he did tell me that the truck he was going to put the engine in was a GMC. Before he got the engine done, some fool stole it and he never saw it again. The valve cover is definitely the two-bolt hold down style. I didn't think to look to see if the block had the side cover like the one in my 50 Chev. Anyhoo, what piqued my interest was the fact that the exhaust manifold heat riser on this manifold is free and moves really well, while the one on my Chev is frozen solid, and I was thinking about swapping manifolds. Does the # on the manifold look like something that would fit a Chev 216 of 1950 vintage? I guess that intake/exhaust port shape and position would be the go/no-go factor?
