360 crank knurling?

Yes, that is correct. I believe the cutter was dull when the decked the block, got it too hot and its not flat and its alot like .009. My machinist said he wants to check the crankshaft (more money). But if he didn’t start digging into it, he would have never have found the bad main bearing bore. Now the main cap needs to be shaved and align bored. Would have been money ahead with a used block and rebuilding from scratch. My advise to you is take it to a trusted machinist and have the entire thing gone through. I don’t build motors anyways. I buy parts, tell my guy what I want in the end. Follow along while he builds it and watch him break it in and tune it on his dyno.
Also koller dodge in Illinois who sold me the sb told me it was a 11:1 compression ratio and its only 10:1. They also sold me a set of push rods “back order “ and I never got them. Those bastards are out of business now. I hope with their rep they never get another job in the automotive field again, every one of them. I hope they get the screwing they deserve for the screwing they gave.
Wow! Thats just bad for business!
frustrating when people feed you s#!t sandwiches just for a sale when if honest, business will keep coming.
Shame!
