Help figure out ratios

Hi everyone,

Can anyone help me figure out my gear ratios in my 18 spline hemi 4 speed?

whats the gear set up in this 4 speed?

Hey chooch

Ran it thru each gear and came up with these counts on each shaft. I rotated the front spline once and counted the splines from start to finish On the back spline.

Total teeth input and output shaft: 18 teeth - 30 teeth

1st gear: 18 - 12
2nd gear: 18 -17
3rd gear: 18 - 24
4th gear: 18 - 30
