Danhr,
The GMPP web site lists the LSX454 crate motor at 620 HP and 590 ft/lbs with a stock LS3 intake and tune. The FAST intake is supposed to add around That comes out to around 500 RWHP with stock intake and tune. With my add ons and a FAST 102 intake, I figured I would easily get into the 550 RWHP range.
Certainly you can build these up to be much meaner machines but I am just quoting the stock numbers offered by GMPP.
Do you have a link to a company selling the 416 forged engines just so I can do some research on them. I am not opposed to more Cubic Inches, just want to make sure the car stays streetable in the long term as its driven alot, nearly daily.
