Wow... I looked at the Richmond Gear catalog, & I am impressed. If I wanted a 3.33 1st gear, the Super Street 5 speed (o.d. version of their 1:1 5th 5 speed) is very nice, same critical dimensions as a Super T10 / Muncie / Saginaw / A833-NP440.
The real gem was the 6 speed ROD transmission.... wow.
4.06 (or even 4 41) 1st gear options, 2.75 2nd, 1.99 3rd, 1.24 4th, 1:1 5th, .76 or .81 o.d....
I'd better look up the price tag so I can stop drooling. The only thing my limited perspective on gear ratios wonders is why they don't have a 3rd option for 4th gear in between those 2, as they have a ton of options for every other gear
EDIT - the only thing I am left wondering is if they have any other available shifter locations then at the very rear of the tail shaft housing. That would be a slight deal breaker, definitely a major deal-breaker if someone had a bench seat truck. They list a GM truck application in their fitment list separate from the others, maybe it has a different shifter location.
