Who makes the best 4 or 5 speed racing tranny? After I get a daily driver, I plan on a stroker with some nasty hp numbers. Don't think the 3550 can hack 500hp. Jerico? Liberty? Some websites would be cool too.

A buddy runs a Tremec TKO behind a 500HP 428CJ that runs 11's in the 1/4 mile on street tires. No problems so far but he's put the hurt on two 9" rears (fixed with the addition of the Daytona pinion bearing support). The TKO is more of a street tranny than the others on your list. Pick it if you want something to use on the street, pick one of the others if it's a dedicated strip car.

What about slicks? I'd be running slicks.

Jerico is the top of the line.

An optimist thinks that this is the best possible world. A pessimist fears that this is true.

If it will see any significant street mileage, stay away from the 'racing' transmissions. The Tremec is a good unit (it's what the 351W powered 95 Cobra R came with). The TKO and the TKO 2 are even stronger. These use a 26 spline input shaft and 31 spline (C6) output. Install a good shifter, and be happy. Slicks won't be a problem.  ------------------

i'd suggest using a Richmond 5 speed, the gear ratios would be more suitable.The Jerico 5 speed is much more money than their 4 speed. They can be fitted with road race sliders to be made more streetable.... besides... maybe it's just todays wuss society where folks don't know how to use a manual window crank anymore  but synchromesh trannies weren't always used in cars.

The Tremec is a really nice street/strip transmission... hence it's popularity. I believe the standard unit has a fairly steep overdrive, but I believe the TKO 2 has a 0.83 ratio, which is really nice. The TKO's also come with large 26 spline inputs and 31 spline outputs... unlike the old Richmond 'Nash' closer ratio unit. 5-speed trannys have come a long way. I'd use a Tremec in a street/strip car in a NY minute. Check out the top vendors for more detailed info. Good Luck! ------------------
