RE: Are the new Thunder Tiger 40s actually 46s?
Greg, I have a 46 that I purchased last year from Tower. It has the CHAMFER at the top of the piston. Another easy way to tell the 46 from the 40 is the gap between the head and the top of the case is much larger on the 46. I hope the 46’s you and Fred looked at were not used in the race?
