ideal gears

with those little itty bitty rear tires I'd say 3.54-3.91

I can't fit any taller tire without stretching the quarters or moving the rear back. I may at some point move the rear back.

My 500 stroker makes 550 HP at just over 5000 RPM. I run 27 inch slicks and 3.55 gears and go thru the traps a little over 5000 RPM at 115 MPH. I'm guessing your trap speed would be similar, so you may want to stick with nothing higher than 3.91's.

I used the drag racing computer. with my gears in 3rd i'll be at about 5700 and with the 4.57's in OD i'll be at about 5700.

So will the car go faster with the 4.57's and one extra shift???
