I want to get on the track! I love racing, I've been off the track for a year and a half. Having a Mopar Sprint Car has been my goal for quite a few years now. I can always make it better and faster as I go. I'll worry about cubic inches later, having a shorter stroke and smaller bore means less rotating mass and better throttle response for the time being.
AND as I said, there's 2 options;
1) a spec head: Brodix ASCS B1BA which can't be modified
2) open: whatever you want as long as the valve angle is within 1 degree of factory.
