ok i ordered a 3mm stroker crank veto's bout the time i thought i should be getting close 2 getting it in the guy from ebay tells me he is out and says all he has is 4mm hotrod cranks. Q is does 4mm give more power and how much will it cost me to have machine work done to put it in? i dont think 3mm crank needs any machine work 2 put in...........i miss riding my blaster any help will be great THX
