The engine we pulled in 2010 had the J heads on it. I think Tim put the J heads back on after overheating it at the track. We sent the Edelbrock heads to Hughes Engines for the Stage III porting and then used them on the 427.

The 427 makes at least 100 hp more than the 360 and the car is about 100 lbs lighter now than it was then. It also has better front brakes, discs in the rear rather than drums and a better front suspension. So while the car was fast back in 2007 it would be significantly faster now.
