Did it feel tight when rotated by hand? Doug Yes it was tight turning the crank with no rods or pistons in it so Yes I screwed up by going ahead.I should be able to get it line honed and get things moving smoothly.I hope the other mains did not mess up the crank so it can just be polished.Wait and see how things work out I can use these to help maybe.What do you think? https://www.summitracing.com/parts/slp-142m1/overview/make/chrysler

would hold off buying any parts untill the machine work is done,then discuss it with your machinist.

So this raised spot that every main has by the oil hole, is this from machining/drilling the oil holes/galleries on the mains, almost like a burr? If so you might not need an align hone, hitting each with a radius'd small hone and working them out by hand might suffice. Id think bad main alignment would've even should up with the looser clearances? You take away .001 to .0015" and now it's to tight? I'd get rid of the burrs (if that's what they are), polish the snot out of the crank and get your .004" bearing clearance back.

Maybe some dye on the area and rub a bearing across it to check or partial bearing with emery cloth lightly.The oil hole is drilled from the crank to the cam so why it is raised idk. ps:the bearing is black for 3/4" on both sides of the oil hole with some along the 3/4 groove on the trailing edge.[fyi]

Thank you for your help on this Everyone!!!Roush did the machine work on the as cast block and as in the past with the oil hole in the cam it is high so if it was honed it did not take it out.I set the thrust after I tq'd the mains.I only did a quick check on the crank and the shop that balanced it I guess never looked.[not that I asked]I will go over it better now[a little late I know] ps: the killer is I asked the engine shop that honed the block to align hone it and they did not want to.[long story]
