I think that's enough of the boring details. If you would like more info on the build, just ask or PM me. The motor has not been dyno'd but is expected to make close to 650 horsepower. The motor is going in my '74 Challenger. Race built Torqueflite 727 automatic. 3,000 TCI stall converter. 8 3/4 rear end with 3:91 posi. 295-50-15 BFG's on the rear. I still need some suspension mods, but that's next tax return!!
