well, my from dampener/ hermonic blacncer losened up and kinda chewed up the front of my crank, and my first plan was to start building a 408 stroker, but now ive just seen the new 6.2 ls3 crate motor 480hp 515 ft it looks like a great replacement, anyways i can get the motor for a prity desnt price from the dealer, the only thing thats stoping me is i dont know if my manga charger will bolt on, and what ill have to change besites the oil pan, witch is hopfully the same, and if i could get it tuned. im very close to buying it should make good power, and looking at the specs it looks very simialr to my lq9, any imput would be great thankshttp://www.gmperformanceparts.com/Parts/showcase_detail.jsp?engine=2
