Started mocking up my 334 yesterday when I put the main bearings in put caps on the crank did not turn as free as I would like. The 289 crank turned nice and easy when I tore it down so I figured the line bore was good. The kit came with ACL standard bearings and a new Scat crank. I will be tearing it back apart and checking all of the clearance's tomorrow. All I was going to do was to mock up the piston's and rods so I can see where I need to notch the bores before I send it off to be balanced. It's never simple. If hot rodding was easy everybody would do it. I know, just take it to an engine builder and pay him to figure out what I can find by just doing some measurements.
