has anybody

one bad 440 said

Sorry guys but I'm calling BS, its an old wives tale. If this were the case then I better go throw out about 2 dozen cranks that are on the shelf on their sides in boxes cause they all must be no good by now. Were talking about a piece of machined steel here... not some flimsy plastic part or something. Not looking to offend just my .02

Yes, it does. Happened to me. Got an OLD crank from a machine shop years ago, turned in a 340 steel to weld up a rod journal and the guy just sold me a old std one he had for 20 years in the back for chump change. I had it polished (free) and torqued it down. Didnt budge..asked the crank guy WTF and he said give it a week and sure enough it rotated like butter after a week of sitting under tension in the block. Crank warpage...And if you store a block on a stand, there is a chance that itll flex,although slim. I have a stroker crank that has been in a box on its side for a few years, will do the same, saddle it up, torque it to 75%, wait a week and them the final torque. Better safe than cracked.
