The T5 (1993 S10 and 1988-92 Camaro/Firebird) is rated for about 300ft-lb of torque and 250 HP. The WC versions are rated a little higher than the earlier versions. I like the V6 Camaro versions and V6 S10 versions with the 0.72 OD gear which matches nicely with a 3.73 or 3.42 rear.
What kind of power does a "reasonably built GMC 270" make?
