freshly built short block with many upgrades!!!!!!!!
freshly built(less than 500 miles) ls1 motor. It has Katech rod bolts, a nitrided crankshaft, speed pro piston rings, and speed pro rod and main bearings. I'll sell the shortblock for 1300 dollars (lowered 500)(I have a lot in machining and parts for rebuild)


It's built for ultra reliable high rpm N/A. They said I could throw a 150 shot of nitrous on it, but i just ran it N/A. I took it out to the track and got one run in before they closed and it went 11.4 at 121. It's an aluminum block.
