[CoupedUp]

The Brock Coupe is designed around the 351 Windsor. You might be able to get something else to fit, but it would probably cost quite a bit in time and money. As far as transmissions go, I believe most people are using the T56. I went for the T600. Main reasons are that the early T56 transmissions were a bit balky (but could be significantly improved if blueprinted - call Rockland Standard Gear in NY) and weighs 25 lbs more. Also, couldn't really see a need in "normal" (under 200 MPH) driving for the .5 OD in the T56. I got my TKO from RSG and had them do the blueprinting to make it extra smooth, bulletproof and run a bit cooler.

Best of luck!
