I had .030 taken off the had on my 630 Gas and it is as far as I would want to go, for actual Field-Work... It is pretty Hot, but no problems with plain old 87 Gas...Peppy, like it had LP Pistons in it..sounds darned GOOD, actually.. Pulled 4x16 F-145 Semi a year ago in Alfalfa/Jack-Wax ground in 2nd gear... ALL it wanted, but sure did itself Proud.. Yes, I had about 250# on the front and Loaded rears, with 3 left and 2 wts, rt.. My 720 will only do one gear higher..(3rd).. I am partial to the Valve-Job I did on the 630.. Polished, re-shaped, port-matched and opened..
I would guess I arrive at Maximum Torque at 950.. For a higher Torque, a different Cam would be needed...
