Slant 6 with 200r4?

you would think that a six cylinder car would have a steeper gear, but then they wouldn't be able to cruise the highway. thats why they went to a low ratio gear set too give them a boost off the line. i'am playing with a 69 valiant that was a /6. it has 2.76 in a 71/4 diff. going to try a 904 with the low gear set and lock up convertor. don't know how it will work, but its a start and it was cheap to build.
