Scott,
I think the TKO is probably OK for Drag racing in a lower HP car .Why not go for a Jerico RR trans? Lots of gear choices but also cost lots of cash.Probably a more cost efective choice would be a top loader.

BTW, we have a Club Cranky member with a Jerico in his Vintage Shelby Mustang racer and it shifts quicker than an automatic.(clutchless)
