Have a look at the Liberty site. I think that you will find that as part of preparing a road race Tremec they fit upgraded shift forks.
Regards Jerico's etc, I went down this path with my last race car. It was a classic racer with 500+hp that was fitted with an M22 Muncie. It got to the stage where I was sure the trans was costing me a lot of time due to slow synchro shifts and limited ratio choices etc. I fitted a Jerico with a Long shifter. Beautiful trans to shift but I picked up less than .5 of a second per lap. I never had any reliability problems but I have also seen plenty of broken Jericos (mainly fatigue failures in high torque applications).
I think Kevin is right when he says that the Tremec should last very well if properly built. It may be that you need to use a trans builder who is experienced with both Tremec's
and Road Racing.
On another note, after having converted one car to a Jerico, if I was going to go down this path again I would want to get the benefit of more ratios (i.e. 5 or 6 speed) as well as having a sequential shift option. If you can go sequential and flat shift then I think you would see some real reduction in lap times.
