Seasoned LS-1 block (better for sleeving) with Katech sleeves installed. Sleeves are finish honed to 4.125 along with all new cam bearings, and align honed with Katech billet mains. This motor is ready for your stroker kit. Make a 388 all bore or a 427 super stroker depending on the crank size. Katech is a leader in GM performance and a major player in the C5-R racing team. If anyone knows this process, it's them. The blocks new without machine work are $3600. I'm looking to get $2500 shipped. Feel free to PM me with any questions you may have.
