That worked ok. Except the time i bought a MP cam that was miss boxed at whomever they had grinding them. After we pulled it out and had a machine shop measured it we knew why it had so much RUMP, Rump, Rump and was a slug with my 323-1 gears and stock 340 converter. for such a large duration and lift.
I did use it with a larger stall and 391 gears. I learned to check the cam before use.
