If you're going to buy a Diamond Jubilee, buy a Mark V. They're just far and away a more pimptastic vehicle.
The 351M and 400 are both based on a Cleveland engine, same head design and such. They'll make every bit the power the Cleveland makes, and the 400 is basically a stroker Cleveland so it can make even more. In stock form though, they pretty well suck. Low compression, lousy cams, bad emissions controls, and putting that de-tuned engine in an extremely heavy and hard worked vehicle caused them to fail horribly. You cannot replace a 460 with a 150 hp 400 and expect it to not suck.
