for the 408 i want to build all i should need from a 6.0L motor is the block and maybe a set of 317 heads. the rest should be eather new parts or parts from my 5.3 or will i need more then the block and heads from the 6.0L?

 

A 408 is a 6.0 bored and/or stroked how much? Thanks, Jim

 

it would be a 6.0L bored .030 over and has 4.000 stroke crank.
