My trans is for sure an FX, definately not a C-4. The door code says my FX was made in Kansas. Cannot find any hi-perf suggestions for the FX, going to swap to a C-4 when the time comes anyways.

Just curious to know if my FX is the same case length as a C-4? Food for thought when/if I have to get a new trans mount when I make the switch.

thanx
