I went with RPM transmissions because I could get a few tweaks and mods that were not available at the time from others (or at least I could not find anyone else) such as machined bronze fork pads, machined bronze shifter bushing, upgraded carbon blocking rings 1st-4th gears as well as micro-polishing, etc.

Not sure if these are items you are interested in, but it may be and it's nice to get the trans-in-a-box to be ready to bolt in.

Thanks. You are correct that is a point to think about. Liberty has a good rep (from what I've read) for their Tremec mods. They offer several upgrades to the T56 also. That is another problem in itself and something I should have also asked at the start of this thread.

Is there any need to modify your T56 for track duty or do they shift well enough in stock form?

I think a fully prepped T56 from liberty gets close to $3500. I'm not in some delusional state I will build my car on the cheap but I do have a budget. My thought right now is put a stock T56 in for the shakedown of the car and if it has shortcomings then I will address it.

That's one thing I havent' decided on at this point. I'm leaning towards having a magnum modified to shift even better. I've caught wind of some high rpm shifting problems with the magnum. I tend to find the weak link with every product so I'll likely choose to do so before I ever stab it.

Not to speak for the vendor, but last I heard RPM retails their Level 6 package for $4995.99. They will give up to $1k refund on a rebuildable T56 core.

These units are tested to 1000 foot pounds of torque.

You are in the same ballpark as the ZR1 'vette, which sees track time and I have not heard too many having issues (I hear more about issues when the tires hop which would not be the case here).

That said, can you really overbuild a driveline? It's just a good excuse to squeeze a bit more out of the engine.

FWIW - I heard the T56 Magnum case is set up to accept an internal pump and has bosses cast for extenal cooler lines. Now if somebody would just make an upgraded shifter that doesn't leak.

Did the White Lightning shifter leak the same as the BlackJack?

According to his build thread it leaked worse and they haven't called or e-mailed him back......

Yet......I'm spotting them a couple of days in case they were at a trade show or event.
