I have an early LS-1 engine that I purchased off Ebay several years ago. I'm told it was used for six 100 mile races. It appears to be very fresh and includes an intake modified with no EGR pipe, harmonic balancer/pully, plus an extra bare cylinder head, camshaft, late style motor mounts, timing chain set, oil pump and miscellaneous gaskets.
It does not have a throttle body, water pump, ECU, wiring harness or accessories (alternator, etc.), all of which are readily available on Ebay or elsewhere.
The headers in the pictures are NOT included.
The engine is located in Altadena, CA 91001 - and I can crate it pretty easily. $1,500 plus shipping, if applicable. Get this thing out of my way!
