not going to get there with that combo. Maybe 13.50 for 12's you are going to need more compression, some head work... can you use the 413?



Hold up a sec, Mr. Y. You are forgetting he has an alternative to the longer arm of the 413. RPM potential!! He can spin it a bit less than a 383 to make power, (and a bit more than a 413) but overall make slightly better times than you posted. Mopar Muscle did a couple of builds on the 400 Mopar with very impressive results. Sure, the car could use a bit more gear, (4.10/4.30, cam depending) but for what he has already, he's almost there! The real power is in the cam and ignition timing and carb tuning. Not as easy as the 413, but you WILL be surprised when it's right!! Have to get carb/ignition spot-on for the combo to really fly!! Concerning the porting templates, Mancini or any major Chrysler Dealer sells them, the part number is P4120437, pretty reasonable.
