The disadvantages of a 351C or 400M are that it is a much heavier block, and bigger physically. If I go to a big block build, I'll run right around the midblock class and go straight after a 460 let out as far as it can go.I had a 351M at one point courtesy of a '73 Grand Torino. Factory four barrel, four bolt main, the whole nine. The S.O.B. nearly bent a cherry picker...

If I ever go there again, I want it ALL!

In the meantime, I have the engine on the deck, and the heads are coming off tomorrow. THEN we'll know what kind of shape it's really in...
