if you have the cam , and it's installed, 373's and 26"tall tire..
the stall is a tad low even for the 270mag..
I years ago ran a comp 292 magnum cam in a vehicle with a 2400 stall and 273 gears and 28" tires.. it was fun at 100+ the cam came on hard at 95mph..
2nd gen t/a's float around a lot at 120+
135+ they are down right scary
