Re: which cubic inch?
thanks everyone...i like the bottom end torque of a stroker and run @ 10.5;1. w/alum. heads/solid roller... just not sure which gear will go through at about 6800 with a 10.5x30 tire...patriot heads will flow well at that rpm...a mezier water pump will keep things cool...

RPM, Gears, Tire, MPH (Engine Inputs): RPM : Rear End Ratio : Tire Circumference (Results): Engine Revolutions Per minute minus converter slip, divided by gear ratio XTire Circumference in Feet =Car Speed in car speed Feet Per minute. devided by 5280 (ft/mile) = car speed in miles per minute X 60 = Car Speed in Miles Per Hour Example 6800X.95* / 4.30 = 1502 RPM axel/tire (* assumes 5% converter slippage) (30" tire diameter X pi. (3.1416) = 94" circumfrence /12 =7.85ft.circumfrence) 1502 X 7.85 = 11793.2 ft/per minute / 5280= 2.2336 miles per minute X 60 = 134 Miles per hour (MPH) Again the assumes 5% converter slip they usually slip between 4-8% Hope this helps.
