Short block is done if someone is looking for a good boost ready LS. Everyone knows what this combo is capable of. If not do some research. Parts and the original post in comments.

Bad ass Bullet Racing Cams that was spec'd for single 94-98mm.(will work with other combo's). Cloyes chain, Meling pump. Coated Clevite mains, coated cam and rod bearings as well. ARP2000 Head studs...yes they will hold the head down with a decent tuner. Will be assembled short block and cam set-up. I have parts to make complete. Waiting for block to get back since first machine shop couldn't follow instructions even after having it for over a year. Will take deposit to hold. Or just wait till I'm done. Price starts at $6500.

Jake Manzke this should work better in Jortz for next "Sick" event. As long as that kick ass 4 speed can handle it.
