Roush 427R TrakPak

Thanks for the pics man but I hate the way those look. They remind me of imports or drift cars. I personally wouldnt be caught dead driving around in one of those. The Mustang is a American muscle car and Jack Roush couldnt have designed that car. Maybe he hired a euro tech along the line. Thats just my opinion but I'll stick by it all the way:flag:
 
427, thats like 7 liters, what do these things have for motors ? I heard jack was working with the new boss motors, the 5.0, 6.2 and 7 liter. Wouldn't it be cool to have a 7L boss motor that would fit into our cars, could happen as these cars are not redesigned 09's. All I can say, " is here camero camero, here challenger challenger hee hee.

It is the stock 4.6 boosted to 427 HP. It's not engine size. He has the 428 coming out really soon which is the 4.6 boosted to 435 HP. Next year will be the 429 with even more power. His other engine projects you mentioned are crate motors and for special projects such as the Ford GT and one offs he builds. I haven't seen where he has replaced the 4.6 with one in the Stang...yet.
