Default 1970 CDV rear gears

im trying to find the most sensible way of raising my rear gear ratio slightly. at 2.92, the acceleration from a stop sucks. id like to go up a little, but no one makes a gear set for the Cadillac only rear end.
so here are the options i have found:
swap rear end. pricey and alot of work.
700R4. this may work due to it's low first gear. still alot of work.
gear vendors. WAY PRICEY!!!
switch pitch. seems viable. i cant find a conversion kit though.
any thoughts?
thanks,
Travis

Default Switch Pitch

The cheapest and most rugged solution is convert your trans to
switch pitch. I use rebuilt torque converters, that are machined
for a somewhat higher "performance" stall speed, without affecting
the low "economy" stall speed. Other things needed are a pump
assembly with input shaft & forward clutch (from most any switch
pitch trans), an oil restrictor, and a 2 terminal electrical plug. To
actually use it, you need some kind of electrical control; there are
several ways to do it.
