I'm considering going ahead and replacing my stock engine with a forged unit in my '01 GT. It has a Vortech V2SQ with 10-12 lbs of boost. It's still running strong, but I know I'm on borrowed time. I have roughly 70,000 miles on the engine since the blower install (been on the car for roughly 10 years now). I would like something that would allow me to push the power up to 600 rwhp. When I first considered doing the swap years ago VT Engines was the hot name at the time, but I have heard that they went down hill and are no longer in business. Whose shortblock or rotating assembly are you guys running in your cars? I haven't kept up with the aftermarket for several years now and I'm just not up to date on who is doing good work. Any help is appreciated.
