Buzz, let me splain to you grin First,the old Muncie ratios are 2.94 in first and 1.68 or 1.67 in second.
Now the 4spd OD I got is 3.11,2.20,1.47,direct and .7 in OD
Now splittin the gears in and out may be ok with a 235 driven like a girle man on his way to a Tapon convention.
But real men like to do board shifts and burn rubber,things a guy shouldn't do unless the OD is locked out,then you're stuck with the straight 3 speed. grin
Did you know that wimpy Muncie spd trans was standard equipment behind the 409's?
