Hey guys, i've got a question here & i'm thinkin i should probly just go ahead & replace this thing but wanted a few more opinions. I know that an balanced & blue printed motor will always out perform one that is not & also that unbalanced pulleys can wear out bearings. With that said, here's my problem. I'm nearing the end of my swap & i'm about to be putting the motor in.. I've notice that there is a chunk missing from the main pulley.. it doesn't effect the belt that i am using but is it going to effect something else being that it can possibly be un-balanced? I'll post a picture later on tonight. also what other years if any are the Main pulley's innerchangable with a B18A1 from a 90 Teg?? Any help would be appreciated. Thanks in advance!
