GM 317 Heads/ 350 TPI/ Spohn torque arm

GM 317 heads off an LQ4 (LS2). Heads were machined, have Manley SS valves, Comp cams dual valve springs 1.32" od ( 0.675" max lift), new guides and retainers. Comp cams kit# 26926TS-KIT. The heads were prepped for a turbo LQ4 build but I decided to go big block instead. No port work, valve job only. (SOLD)

Have complete 350 TPI long block with 700R4 have ECM and wiring harness. Willing to part out, PM me for more info.

Spohn standard duty adjustable torque arm. Has poly mount. Some scratches and rubs in the powder coat. $175

Selling to make room for my 468 BBC 4l80e build.

It is part #310 for a TH350. I have the cross member but modified it when trying to use it for my 4l80e swap. So i did not list it.

Well what good is that torque arm if it requires a Spohn crossmember in order for it to work? Now someone has to purchase a crossmember separately from Spohn and that isn't even a sellable part on its own. if Sphohn did sell the correct crossmember for it then it would cost at least $120 considering that's what their standard crossmembers cost. You're asking $275 for the arm and now add another $120 for the crossmember. That's $395, same cost as a brand new unscratched one directly from Spohn.

Spohn sells there crossmembers and torque arms individualy. Part Numbers: 3TAXM, TAR-3, and TARX-3. See link:


http://www.spohn.net/shop/1982-1992-...d-Torque-Arms/


I see your point on pricing. I based my original number on the individual torque arm price and not total kit value. Need to do better homework. Price reduced to $175 shipped. If you order the xmember seperatley ($165-200) you would net between $50-65 in savings over the kit. As with anything price is negotiable.

So is this essentially the tar-3 arm? If so, I'll offer $140 shipped to 60446. PayPal ready, lmk
