Main stud torque spec Got ARP main studs on the way since my engine is out. Thought I would clean up and upgrade a few things. I'm thinking the studs will have a slip with specs on it when I open the package but I just wanted to do my homework. I looked on ARP's website and the only specs they have are for rod bolts. The Chilton manual didn't seem to have anything either. What's the proper torque specs for main studs in an LT1?
It is the same as any other SBC. Make sure to use the moly lube on the threads before torqueing them down. You should be able to torque them to 65 ft/lbs with the moly lube, but if you plan to use engine oil, torque them to 70 ft/lbs.

These torque specs are for bolts, he's got studs.
For the original poster, did you know that you have to align hone the block/mains to allow using studs? The studs clamp the mains differently so it must be align honed.
I was planing on going with studs but when I found out there are no align honning machines where I lived I just went with ARP bolts.

I double checked with ARP, he said check the tolerances but I should hone it (he admitted he had to cover his butt). He also said that if it looked good, then just run it. My buddy that's gonna be double checking me said we should be fine too.
