Jerico WC4-4?!?!?! ...are we going Winston Cup racing, or drag racing?
For drag racing (1000HP launching on drag slicks), I would recommend the DR4, should you decide to go with Jerico. I have been running one w/ a Long V-gate shifter for the past year and love it. It is not designed for street duty, but with some finesse it can be used, althought Jerico doesn't recommend doing so as it greatly reduces the effective life of the tranny.
Another company to look at is G-force... they have several different boxes to choose from as well, depending on what your intended purpose is, as well as your budget.
Where are you going to be racing from a 20mph start w/ ET streets anyways?
...and why?
Also, I wouldn't be asking for a trans that shifts similar to stock, as the H-pattern shifters are a joke once you've made a pass down the 1320' with a V-gate
...and the internals of the DR4, for example, allow for effortless, ultra-quick gear changes, without a worry in the world of missing a gear.
A Jerico can be had for just over $3k, and you'll want to go with a long style, adj. pressure plate w/ a sintered iron disc clutch setup, which is also nice chunk o' change.
