Okay, so I'm building my first engine. Mods are in profile, and everything in the short block is what I will be using. I just got my block back from the machine shop, bored .02 over, and fitted for clearances with my Wiseco 9:1 pistons. I'm using Eagle Connecting rods, ARP everything, and everything plastigaged fine.

HOWEVER, I'm having some issues. With nothing but the crank bolted down by the mains, it spins free, easy, and makes me smile. When I attach even one piston/rod there is a slight "rubbing" sound when the piston reaches the middle of the cylinder. It's not as bad with just one, but when all 4 are in it's a lot harder to turn the crank. A lot harder. When 1&4 are at TDC and 2&3 are at the bottom it is free and has no rubbing. As they traverse down the cylinder bores towards the middle the rubbing and friction begins. As 2&3 reach TDC it goes away.

I can't figure out what this is, and I sure as hell don't want to put it to gether like this. Anyone know if this is normal? Maybe my machining is off? I can't get ahold of my machinist until tomorrow, but this really has me worried.

Thanks
