Stick Cars:gear Swap Results

this all depends on hp vs torque the bigger cubic inch engines can run a higher gear ,even though the cam shaft may have a crazey duration ,smaller engines need a lower gear to perform,this is not news to most but,stockers try to run out the end on rpm and some times big cubic inch engines suffer,i put it like this ,i had a 455 buick, i could throw the brick on the gas pedal and it wouldnt rev past 5000 rpm free wheel no matter how long it sat there,it wouldnt blow up ,it would 60 ft like crazy but you where i high gear way before the 1/8 and you where hanging ,each application is different good luck gmonde

Rear gear & tire size for finish line RPM & MPH. Transmission gear ratios for leave & split times.
