Josh, if the motor is high mileage, you would be well advised to bore the block .030 over, hone, install new hypereutectic,stock type pistons, correct ring package. This will guarantee straight bores, excellent ring seal. Competent stock valve job, use the cam manufaturers recommended spring package. Don"t forget to turn the crank .010 under. This will guarantee round journals, proper bearing clearnance, correct oil pressure. If you deck the block, just do enough to guarantee perfect gasket seal. More and you will run into intake manifold alignment issues. The 460 crank could be selected at this point with the new pistons, which must match the crank selection. If you run a stock convertor in the trans, stay conservative on the cam timing. If you run something like an 11 inch/2800 stall, you can run one of the new "Thumper" style cams from Comp cams. It will sound cool, and go like H... Stay conservative on the carb, 650-750 max on the CFM.
Hope that helps your thoughts on this, Gil
