Read my post above,.....it really likes a four gear! pulls extremely strong in the 3-6K range,,,,,makes for a brutal assult on the driveline, I've popped about (3) 8 3/4 carriers, 3.55-3.91's racing, I'm running a Hemi 4spd and an 11" Hays BorgBeck 2800 lb pressure plate and a Kelvar disc behind my 340/6, I used to run a 3400 lb McLeod, but that was a bear on the streets, nevermind my leg!
