Slant 6 with 4 speed

except this;
If you got a slanty, you need the early-A box, with ratios of; 3.09-1.92-1.40-1.00. It has a lower first gear for better take-offs, and allowing a better hi-way gear. Centering it up at second =37.3, like the other ones and using 3.23s, check out this sweetness;
let the shift rpm be 2874;
your shift speeds will be 23.2, 37.3, 51.2, and run 4th up to 65=2608rpm
The rpm drops will be to 1782, 2095, 2052, and
the mph in each gear will be 14.1, 13.9, 13.84.. Badaboom!!
