Small block strokers

Those pics are of 727s. The drum in a 727 is so large in dia that when a sprag lets go the drum speeds up beyond its RPM limit and boom. The 904 drum is smaller in dia, and can handle more RPM before coming apart. You rarely ever see a 904 come apart like those pics.

Ya, I specifically looked for pics of exploded 727s this time. After seeing everybody's feedback about the 904s, I'm starting to wish I'd headed in that direction. The way things stand now though, I'm sitting on a lot of 727 parts. I've already got that 'race prepped' 727 with 2 extra manual shift valve bodies (forward and reverse patterns), an as-yet uninstalled overhaul kit, and a stall converter.
