tq specs
 
anyone know the tq spec for the flywheel bolts and pressure plate bolts? thanks in advance

The flywheel is something like 25 ftlbs + so many degrees. I dont remember though. I know that dont help but its not just a straight torque number because the bolts are torque to yeild meaning they are one time use only. I put ARP bolts in my car and they get torqued down to 50 lbsft.

im sure its a higher spec than that... also, i have ARPs and the heads are to tall to use them. im stuck using the factory ones.., kinda sucky but im not making big power any more so i really dont care.

I just bought some ARP Flywheel bolts, and am also wondering what the torque specs would be on them. The stockers are 39 ft/lbs + 25 degrees. But since the ones i have are not torque to yield i'm not sure of the required torque specs to hold my flywheel on reliably

**Update: after i did a search (duh) on my flywheel bolt part # i found ARP's specs, here is for all if you are interested as well. These bolts only cost $26

ARP 4AG flywheel bolts (part number 203-2802):
Blister pack contents: 8 flywheel bolts, instructions
Torque spec: 58 ft*lbs (with ARP moly lube), 63 ft*lbs (with Loctite), 85 ft*lbs (with 30wt motor oil)
Source for torque specs: ARP technical rep from 800 line**
