I have a 383 that has an unknown non-stock cam in it that I need to replace. The engine is in my 63 Sport Fury. I am seeing areas on the bottom of 4 lifters that indicate at some time the lifters did not rotate. I want to replace the cam before I do damage. The engine has been balanced and has some head work done but I don't know the extent. It is in a strictly street car with a 4-speed that will never see a drag strip. I am running 3.23 rear ratio. I am looking a the following cam, any comments on this cam or other suggestions would be appreciated: NEW - Hyd. - 284 / 284 Duration - 484 / 484 Lift Street/Improved driveability $214.95 MOPP5007697 This is a Mopar Performance Cam from Mancini.
