ok i have a 89 f-150 4x4 with a 302 aod at 390,000kms it smocks a bit but it leak a lot .so i built a 82 H.O. block from a mustang and put in a cam from summit sum-k3600,448in-472ex,204 dur-in,214dur-ex with stock 78 heads headers off a 87 mustang and duels think it will pull better than a 00 dodge ex cab with a 318,auto???
