Trying to find info on my crankshaft bolt from ARP. Its a 12 point but I cant find any info on the head size...Looked on ARP website, all over the internet and even gave the guys at Pep Boys a shot at figuring it out (obviously they had no clue, lol) Im trying to send a pic from my phone to my comp for upload but was wondering if anyone knew off hand what I am talking about till I get it loaded up. Unless anyone can tell me another way to turn over my motor to set up the valvetrain...
Thanks

Probably a 1 1/16" ?? Go to sears ? get a few sockets , find the one that fits and take the others back !!!

It should be a 1 1/4 head 3/4-16 NF thread bolt. Length depends on thin or thick damper as well as aftermarket. Most aftermarket dampers use the longer 2.25 length ie. Fluiddamper and CAT.

It also looks like a 12 point socket is needed

Looks like TVLynn didnt read you post...
