I have thousands of passes under my belt over the last 32 years. Never blown one up into pieces even with running some pretty serious 9 second Street cars. I have lost reverse, and second in a couple different cars and different transmissions over the years but nothing major. I always run a huge cooler and do high gear burnouts. My current torqueflite is a CRT with a J.W. SFI Bellhousing added that I bought from my buddy when he went to a Glide. Hoping it holds up to what I am putting to it.
