493 John...it has an H pipe.
mopar dave...It's 11:1. Makes somewhere north of 800 hp on motor. It's been 9.50s at 140+ mph on motor only at 3800 lbs. I've been 8.90s on nitrous, but should be in the mid 8 sec range now. I've been a good bit quicker at 1/8 mile tracks since doing some tuning. Just haven't had the chance to run it at a 1/4 mile track in a while.
