Here is a bookmarked site I found that talks about TCC lockup. It is somewhat technical but what I gathered from it is that there are kits that control lockup with an adjustable vacuum switch. The 373 rear gear ratio seems to be the preferred option but it depends on the weight of the vehicle,tire size, engine torque,shift preference, and many other variables. I suggest you contact Bowtie or TCI transmissions and give them all your specs.
