So sorry to here that Kev. You have my prayers. I wish you luck on your quest.

My vote would be to keep the 428, pure and simple. BTW... have you thought about those weak LSC sourced 28 splined axles that won't hold up to stroked 460? How about that radiator that just can't handle the heat that 521 produces? Not to mention that radiator cooling fan that doesn't move enough CFMs to handle the increased heat load. Been there, done that. The sad truth is that the 521/injection represents about 50% of the "quest for HP equation". The rest is also very expensive and very time consuming. Jus' sayin'...
