You bring up good points. I know the cranks an teksid block can take a lot of abuse. I know the weakest link is the rotating assembly are the rods and pistons. Al Papitto's 96 Cobra was making 462rwhp using a 00' R motor. I know boost is the quickest way to get there, But i get tired of reading all guys using a Centrifugal chargers throwing belts. I may just do a whippled DOHC 5.4. the world may never know as its gonna be a few months while i decide which route to go.
