1967 Barracuda Slant Six to 440?

Here are some pictures of the internals of the 440. I have been measuring all the journals (main and rod) and they ALL seem to be 0.010" under. All the bearings I pulled out had a 0.010" stamped on them. So I figure I need 0.010" over bearings. But my block had no maltese cross stamping on it, which I read indicates a 0.010" over block. It certainly did have 30,000 miles on it, as it had literally no wear. I know it was never rebuilt before either. Strange.... the casting on the block is 3698830.

Also, how do I figure out what type of crank and cam this is?













My heads also have different numbers on them:







I plan on re-using my crankshaft and rotating assembly but I'm replacing the cam. I'm also keeping the heads and getting stainless steel valves for the exhaust.

Any suggestions or comments? Thanks!
