I just ordered some main bearings from acuraautomotiveparts.org and the guy sent me a email saying
"I will need to know what color(thickness) main bearings you need. The wrong size will damage your crank. Check your service manual, there should be a chart for that. "
I bought the ls block from the junkyard and dont have the service manual. The block was from a 91 acura integra 4dr ls does anyone know what the "color(thickness) is"?

No one can tell you, only you can fig it out. There are numbers stamped on the crank and numbers stamped on the block. You have to use those 2 (one from block and one from crank) numbers and use the chart in the manuel. OR you could post the numbers from both and someone with a manuel could help you.
