Ok Guys... Been trying to fiqure this out but need help. Last season I ran my '72 mod gp292 with either 11/25 or 12/25 and one track i dropped to a 10/25 gearing with 7 tooth drivers. This season I am building a '73 SR292 and will be running 8 tooth drivers. Leaving my 25 tooth bottom gear alone, how do I determine how to keep my ratios the same?
thanks in advance
