    Default LS9 long block with cut crank snout wet sump operation. Ported heads. your choice cam

    Description:
    I built this for my '69 Chevelle project; however the alum 5.3 I have in it should be fine for my needs. This was a GM warranty engine I bought and then had machined to my liking by Joe's Engine shop in Concord, CA. They built the LS9 in my turbo RX-7 (this is a different engine) and I beat the living daylights out of it for 3 years doing 1/4 and 1/2 mile events. Joe's does good work. These shortblocks are VERY hard to find.

    LS9 block bored to 4.070" with torque plates (billet main caps, piston squirters, 130 ft/lb of torque for head bolts!)
    LS9 crank with cut snout for wet sump operation (std/std journals)
    LS9 Pankyl Titanium rods rebushed with Katech bushings and ARP bolts
    RaceTec forged pistons (10:1 compression with LS9 heads)/rings setup for boost and pistons checked for clearance with squirters (I have made 1400hp with these pistons/these are ex JE piston employees)
    Calico coated main/rod/cam bearings
    Lingenfelter ported LS9 heads with dual .650" lift springs, upgrades exhaust valves and factory Ti intake valves that flow 350cfm+, rocker arms with new BTR trunion bearings
    LS9 head gaskets, ARP head bolts (torque to 130 ft/lbs), LSA valve covers, no coil packs
    ****your choice of BTR camshaft (hydraulic)**** ($300 credit if you have your own)
    LS7 GM performance lifters (or you can opt for Johnson 2116 link bar lifters (add $400))
    BTR pushrods
    your choice of Melling oil pump, IWIS timing chain, LS3 style front cover, new rear cover.
    no oil pan, pickup tube or windage tray (I can supply if needed), no blower or accessories
    everything has ZERO miles on it since rebuild. I have the shortblock assembled and just need to install cam/lifters/heads which are also done. Could ship within 1 week after camshaft arrives. I always build a proper crate and it WILL arrive safely with insurance.

    $10K plus shipping


    *** the main reason why this is desirable is the heads can be torqued down to 130 ft/lbs which is 50 ft/lbs more than any other factory GM block plus the billet main caps and piston squirters are a bonus. The LS9 block is also cast from a better grade aluminum and like the LSA heads they are rotocast with better grade aluminum as well. I made around 1400hp flywheel with a similar motor for 3 years and NEVER lost a head gasket. 88mm turbo on $2 e85.
