Do you put you burgers in the fridge for a few minutes after you make the patty's? I find that helps. THough last night all we had was course ground burger, so it was a **** to get them to stay together. I don't like to "over work" the meat. LOL Right now my car is REAL slow. No motor, half a harness, rear about to come out. I did pull the pan off the old motor last night though and found everything is studded and a windage tray. Press fit crowers on TRW's. Had ARP bolts on the flywheel. It's all ballanced. The flywheel had been lightened in a lathe. Yikes. To bad the original owner killed the rings, I think anyway. Never did do a compression check, it was coming out eitherway.
