ARP Crank Studs for 318LA

The fact that it turns is not a big deal. The question is, how flat and true are the journals? Studs will pull them out, but may not be enough to pinch the crank with the bearings. That doesnt mean it will last, or that the oil film will be good enough. I have most of the fancy measuring tools. But I can only measure the bearing bore size and taper. I may not be able to see deflection. Not that it's uncommon to think like your shop does. I know of a local BUSCH series engine "builder" that doesnt cut valve seats in the new heads, becuase "the roller springs are so stiff, after a lap or two, they seal just fine..." Another one of his quotes..."Why are you so particular on the bore size (main bores)? When it's all bolted together and torqued, the bearing clearance will average out to be fine..." That was when I questioned the results after I had him align hone a block. I've known him since he was in his early 20s (over 15 years) and was the disassembly guy at a well known shop. He's got a decent rep, which is scary to me. He is a great guy, but the "meticulous" went out of his work years ago. Needless to say, he does not do any work for me anymore.
