Trw forged pistons, stock crank turned and balenced,206/206 billet roller,weber heads,weber ported intake, center billet mains,arp hardware,harlen sharp roller rockers 1.60, o ringed heads. I bought this motor from a fellow board member a year ago put about 2000 miles on it tops runs awsome. I had a pt-61 turbo on it and with a low boost and very conservitive tune went 11.20 at 124mph with a 1.8 60ft. So this motor will for sure go well into the 10's. I am selling cause I had Weber build me another motor that is getting put in this weekend.$5000 shipped!!!
