325HP stock. 620HP with 15psi of boost. With a forged engine and 20PSI...I sure hope that rear end can handle 800HP. What are the widest tires that will fit on the rear end without tubs?
BTW, I'd love to see this on the scales compared to the stock engine. It'd be interesting so see how much more/less that this combo weighs.
(Edited my above post to account for a more boost friendly compression ratio of 9.5:1 instead of the stock 11.5:1.)
