This is the engine from my GT Camaro. 305/313 NHRA GT rated. Built from new LSX Block, Heads last updated by Hettler, Std crank and rings, Manley Rods and Valves, Jesel Rockers, Comp cam, Cometic, etc. Has been 80 under. Was 76 under last weekend D5 national open Kearney Neb. Sold complete Throttle body to pan. Is setup for remote oil filter. Engine has approx 80 runs, and is setup to be very reliable, there is more e.t. there. I run it with an alternator now. I would run it as it is to 200+ runs before rebuilding. I won 3 races @ 6-7 rounds with it this year. Maybe should keep it, but I like trying new stuff. Converter also available at additional cost. Other details on engine available to very serious buyer. Many years and dollars spent to get to this point. Engine will not be available after 1st of year 2017. Need time to get replacement built. Not looking to separate anything.
