Re: BIG Ford Combos?
 
400 2bbl has low compression and huge piston tops....but...I think they have a lot of potential. Still, I think the 351M would be better than the 400 for the same reason a 302 is better than a 351W, same breathing (carb/heads) with smaller cubes.

2.05int and 1.72ex valves plus big ports in intake, the only issue is carb cfm which I think is 350cfm if I remember right. As long as you modify the oiling system (restrictors in the cam feeds) I think it would stay together. Of course the availability of aftermarket pistons/rods is a pain, but you know it won't spin up past 6000 so who cares?

Not a record holder but I think it would beat the index.

351 crank and pistons....now you've got a 351M instead of a 400.......
