Not to mention the fact that the 370 will live longer and rev higher than a 408.

Yeah, but a 408 chews the piston skirts up from the first time you crank the engine. The cast iron block has cylinders too short for a dependable long life with a longer than stock stroke. If you precision balance both engines the 370 will run sustained high RPMs much longer than the 408 ever will.

When the cylinders are as short as they are in the 6.0L the pistons tend to rock in the cylinder at the bottom of the stroke and the bottom edge of the cylinder cuts the skirt. I have some wonderful pictures of the damage a 4" stroker does to a 408" engine. Yeah, I know a 4" stroke works on some engines but it doesnt work on all engines. A 4" stroke is great in an aluminum block GenIII but the cylinders are longer and the pistons stay stable at the bottom of the stroke.
