1965 Mustang BW T-10 (HEK-M) gear ratios
According to mustanktek the BW T-10 (HEK-M) in my 1965 Mustang has a 2.36 1st gear. I have mine apart for rebuild and I calculate a 2.74 ratio for 1st gear. Here are the gear tooth counts (MS= mainshaft, CS= countershaft):
1st: MS 36, CS 17. 2nd gear: MS 30, CS 19. 3rd: MS 28, CS 24. 4th: MS 24, CS 31.
I calculate 2.74, 2.04, 1.51 and 1.00 ratios for 1st through 4th. I understand that 4th gear is straight through (countershaft has no effect) and for the other 3 gears I have taken into effect the countershaft. Am I calculating incorrectly?
