Default 351 C4 guys...question on front main seal lifespan

--------------------------------------------------------------------------------

THe other day I had the pleasure of losing a front main seal on my C4 MIghtMite tranny from Dynamic Racing while shifting hard from 2nd to 3rd. Big smoke show

I have about 2000 miles total on the combination over 3 years and about 35 passes at the strip. Been a VERY reliable setup. I'll be yanking the motor ASAP to replace seal. Cause for concern or typical wear?
