Check with some of the Church Boys threads on this site, or contact him directly...he'll be happy to help you. As far as drivetrain combinations, that falls directly under personal preference. My drivetrain consists of a ~700 bhp small block Chevy, backed by a PowerGlide, and a Ford 9-inch rearend with 4.86 gears. My car, weighing 2780 lbs with me in it, ran mid 9.80s ET at 1900' of altitude (a little quicker at sea level) without a throttle stop. You can probably get away with a milder set up to run the 10.50 ET, or slower, that you're targeting.
