257 shouldnt spool that much later than 252 and should be able to make easy 450-500. I hope your motor is built Sent from my iPhone using Tapatalk

The motor is completely stock, held together with a set of ARP head studs. I'm really only looking for 300-350hp max, which seems to be the sweet spot for a reliable setup with stock internals. I just daily the car at the moment with some spirited driving on the side, I think it will cope just fine.
