I reused the same bolt, red lock tight, impacted it, then put a 2ft bar on it with a small cheater.. Fine no probs what so ever.. The pulley is more less pressed on.. The bolt holds it from walking off..

Sorry to bring this back from a year ago, but it's relevant.

When you don't have anyway to measure 250 ft lbs. of torque, just hit it with a big impact for a few seconds?

I have two "highly technical" ways of torquing the crank bolt.

1) half inch ratchet with my jack handle on it and put my 160# *** on it bounce it a bit
2) hit it with the impact til the pulley bottoms out and hit it a couple more seconds

Use a little dab of red loctite in either method for both stock and ARP bolts, never had a problem in all the ones I've done.
