Stock 49, that is acool chart, to look at. The one variable that is left out of the equation is tire diameter. What size tires are stock? What size do you plan to use? Here are the numbers that I come up with for the 2.56 ratio that would be third gear in OD.with 3.55 gears at 70mph.
With 30 inch tires:2007
With29 inch tires:2076
With 28 inch tires:2150
With 27 inch tires:2230
With 26 inch tires:2315
That's using the formula of: speed x gear ratio x 336 divided by tire diameter. In my experience the published tire diameter works ok at the kind of speeds that are run on the street. Basically tire growth and slippage cancel each other out. (not like the rear slicks on a top fuel car). But I have to agree with you and Beater that even with 26 inch tires that dropping to 1:1 on hills will probably have to happen with the cam duration that you are running. Jay
