you buy the car, you can put whatever engine you want in it. But the "OEM" motor for the Coupe is i belive a 410 CI stroked Windsor by Roush Racing. I believe the rear is the 8.8 inch IRS used in the roadster SPF's, the one from the old Ford Thunderbird SC car, aluminum diff housing, with custom axles. But the pickups for the rear A Arms are much closer to the car's centerline. Transmission is the six speed T-56, although i don't know what the internal gearing is for this application, as several different gear sets are available for this Tremec. My guess is the fifth is .80 and sixth is .62, but again, i am not sure.
