Great, after talking to you all, my dad and I have decided on the 71 or 72 455, it seems that the 72 parts are in more supply and basically the same motor, just with different part numbers. Don, I appreciate all your research for me and all the numbers. What duration cam would you suggest and as far as converter and rear gear ( as a fellow post says 4.56 or 4.33 ). After talking to Hefler he says A1 or Munsinger makes a great high stall converter. What stall would you guys recommend for my torq machine? Don, I am with you 100% and appreciate all the great feedback!
