You go from a 3.26 (560) to a 2.63 (450/400) R/P ratio. I don't know and never have firgued the % but I do know the ratio. That is the standard R/P and there are others but I don't know them and have not firgued them

Ran a 450 set up for a while with a home built set of transmission gears then changed to a faster set of constant mesh gears with the 560 R/P. Not sure what you are calling half gears but the ratios we have now are 18-1, 19-1, and I believe around 21-1/22-1. Stock road gear is 18-1 if that helps you any. Is this in a Profield , LLS, or Prostock? I,m running this in a Profield, 3000 rpm, 18.4-38's, 360 cu,no turbo or pump limits.

There are 3 that I know of. 15/49 out of a 560. 19/50 out of an M or 450. 19/47 out of a 450 hi-clear. There may even be one that will work out of a 660 but I can't remember for sure.
