Hey Eric. It's the original 302. About 800 miles since the rebuild. The gory details: .500 lift cam 9.6:1 compression roller rockers flat top pistons 670 street avenger carb. headman headers I probably get it out a couple times a week weather permitting.(crazy Mich. weather). Hey zooomzoomguy,I'm up here in Shelby Twp.(we need a michigan mini meet soon!)
