Default C5 Stall fit LT1?

All converters i seen have listed under C5 ls1 and Lt1 4L60E, I take it that they fit both? Would a C5 trans fit a LT1?

both yank and TCI list the LT1 converters with their C5 converters.

Ive always read that the converters would swap.

Yep, its the Ls1 F-body stall that wont work. C5 will, though I have never tried it, I have been told the C5 and LT1 can swap stalls.

Stall speed is stall speed though. If it fits what you need it to fit, then it doesn't matter what else it fits.

Yes!! I have a Pro-torque converter out of a 98 vett in my 97 Z28. Now a LS1 F-body converter will not.
