there is another LIM other then the ShoShop one. its from the cougar's, its refered to as the returnless LIM, its bigger then the stock one by a couple of MM, i believe the stock svt is 33mm/34mm, dont quote me though, and the "returnless" is a 34mm/35mm (i know for sure on that), the returnless's come off 99+ cougar's and can be found on
www.car-parts.comgotta question for you though, why do you want to move the powerband higher up?? right now the powerband is from ~3500rpm to redline(WOT) and if your not WOT then it is ~4000 to redline, what more do you need, thats plenty i think
