The father in-law just gave me 1973 challenger with a 68 dart 340 with WW2 heads. Tore the motor down as it was not stored properly, it has a new crank and pistons but who ever put the motor together didn't clean the engine properly and the bearings have score marks in them. The bearings are Dab bearings with the numbers 83 7132 CAP L 0-39 0-39 D49 and have .010 written on the underside of the rod bearings, and the main bearings have .010 written on them as well. Can someone tell me what these numbers mean or where I can find some information on these bearings. I don't know if this .010 oversize or .010 undersize. Please help.
