  • Price
    $2,600
  • Location San Ramon, CA, 94583, USA
  • Condition Used
Description:

Fresh 4.070" LSA block with Molnar 3.622" forged crank (58x and 6 bolt rear flexplate style), Molnar PWR ADR rods with ARP2000 bolts, CP race pistons with .230" wall wrist pins, machined, balanced and assembled, file fit rings for boost assembled by Joe's Engine shop in Concord, CA (used to run NHRA... they have built a ton of LS engines for myself and buddies including an 1800rwhp R35 GTR engine that dominated in our area without issues aside from transmission hahaha). Includes ARP2000 head studs  ($450) that were used for the torque plate/honing/boring. I kept the stock stroke so that it wouldn't lose the piston squirters when using a stroker crank.  Once again this is for a 6 bolt flywheel/pressure plate not the 8 bolt style LSA.
$8K

1 set of freshly done LSA heads CnC ported by Gromm Racing, performance valve job, LS3 intake valves, LY6 Inconnel exhaust valves, new guides, BTR .660" lift spring kit $2600

If you buy both and pay shipping I will crate this up for free in a very secure pallet/box.  If you need cam and other related parts I can source those also.

To complete this you need all timing parts, front/rear covers, cam/lifters/pushrods, head gaskets, valve covers, oil pan, oil pump.  I believe I have a set of LS3 rocker arms and will check this week.  I have a set of used valve covers you can have and a used front cover.  I can assist with getting the other parts if you want BTR stuff.

Not sure why I didn't mention it... but with a .051" LS9 style head gasket the LSA engine it would be 10:1 compression which is great for e85 and boost.
