: Any idea what a LS2 short block is worth?

11-24-12, 02:28 PM
In preparation for the purchase of a forged and balanced LS3 short block, I'm trying to figure out how to get rid of my existing block. I could sell it as a short block and keep the heads, valves, springs, rockers, and whatnot (I doubt 243 heads are going to hold me back when I add a TVS2300), or I could say "screw it" and buy a set of LS3 heads, Yella Terra rockers, and a LS3 intake manifold while I wait for my savings to build up again.

Here's what's I'd potentially sell with the motor. If you could give me a rough idea of what I could reasonably expect to get for it in a short block and long block configuration, I'd appreciate it.

- 364 CID LS2 with 26,000 miles. Redline 15W-40 diesel oil flush and fill with zinc phosphate additives every 4,000 miles. 422 RWHP / 383 RWTQ in this configuration with similarly thick tranny and diff oil (est 0.83 drivetrain losses). Oil pressure on 15W-40 60+ psi at WOT and 42 psi hot at idle.
- TruTorq L3 cam (223/236 .610/.612 115 LSA) AND stock LS2 cam
- 7.425" Comp hardened pushrods, retainers, shims, and locks
- Comp 26926 dual springs (.675 lift)
- Comp rocker trunnion upgrade
- Newly installed valves, seals, and gaskets
- Pinned crank
- Professionally ported LS2 intake manifold
- Stock fuel rails and injectors
- Stock LS2 oil pump and chain

I sold my stock longblock with 64k for 2200 locally.

as for ls3 heads. I would recommend that route. $600. they flow better. You can get the lighter sodium valves. Plus it opens your TVS 2300 options up to both maggie (G8 kit) and e-force

As promised on the LS1Tech forum. Super impromptu. Hope you like 0:54-0:56. Valvetrain sounds 3x louder with this camera than in real life. Hawk HP+ pads were cold and squeaky.

Why not LSAs?

Why not LSAs?

Do you remember the cast number on those?

Nope but the GM part number is 12610716. I should have them in hand by 12/2.

Make that Dec 14 - just got an update from Summit. If you want to see stock LSA head flow values check out the "head" thread in the V2 forum.

Thanks. I'll make a note of it.
