Lateral-g Forums - 454 Cu In LS7 short block (Darton M.I.D., Callies, Titanium rods, Katech Pistons)

SOLD./..

I originally had the rotating assembly listed for sale but now the entire package is available. Cost me close to $12K to put together, but I no longer have a car for it to go into.

I've decided to sell this short block assembly "unassembled". I know if I were purchasing these items I would like to do the final machining assembly or have the engine builder of my choice do the work.

Included in this package...

LS7 BLOCK

-the block started as a new LS7 block in march 2008
-It was recently ( last week) resleaved with Darton M.I.D. liners by Steve @ Race Engine Development ( will require finish bore, hone, rod clearance)

-Machine work completed on the block
1) stress relieved
2) machine /install/ "0" deck block
3) includes ARP main studs ( used for align hone)
4) cam bearings installed
5) GM billet main caps
