Not Ranked
typical Cobra loses 20% but with you IRS maybe a 25%.
20% loss, your motor would be a little over 400 flywheel, 25% about 445.
a 427 RACE motor, back in the day, made about 525 flywheel.
I would think you could get 475 - 500 and still keep it streetable.
A couple of my buddies have Keith Craft FE strokers. One a 427 stroked to 487 making 618 flywheel hp. The other is a 428 stroked to 461 making 601.
Both are very streetable and fast.
Keith can CNC your heads and pick a cam for your street motor. If your short block is good let Keith do your heads and buy a cam from him.
