I have a question about Primary belt pully ratios. I've read that the standard is 31E and 47Clutch I just checked my 8mm 11/2 Primo pullys and they are stamped 39 and 62, this is followed up with 24Trans 51 rear. I've done a search here and find a site posted by Jack but for some reason I can't bring it up, can someone help me find what my final ratio is? Oh yea I should mention this is a 1960 stock trans and frame. Thanks
