I have a race in a few hours and I am trying to find out the appropriate clearances for rod and main bearings. This is ONLY for a full race turbo b18c5 engine pushing out over 500 hp.I damaged some green colour mains and could only get reds which are giving me the following clearances. Right now I have 1.5thous on the rods and 2 thous on the mains , I think the motor was originally built with higher clearances but I just wanna make sure. Please do not quote helms as I have already checked it. I need feed back quickly from someone who builds race motors. Please pm me thanks.
