Thanks to my stock bottom end spinning a rod bearing, I'm going to be building up the block. Upgrading all the internals, then going for more boost. Car is a 1997 SVT Cobra 4.6 with the Procharger P1SC intercooled charger setup. I am wondering what kind of power you guys have been able to achieve this similar setups? My tuner is hoping to see 600hp or so at the wheels after the new motor gets in. Any info or tips from you guys who have been thruogh this before would be greatly appreciated!!
