Many manual trans problems can be traced to alignment, shifter, and wear issues. Many a cracked trans case can be traced to the use of a solid rear trans mount along with solid motor mounts. Speaking from experiance, even the highest powered drag cars using such pieces require the use of a rubber trans mount even if solid motor mounts/plates are used. This does not apply to the Liberty/Lenco level of performance, but the average 8sec car uses a rubber mount. The Vega we set up with a Jeffco had no rear mount. Even a low powered motor can muck-up a trans if things are out of whack. Me? I'd take a Liberty crash box made from a Hemi 4spd if I was still racin...assuming I just got tired of using a transbrake 'glide:).
