8.75 durability for big block street/ Strip

My car broke it's 8 3/4 the second time the then new 408 hooked up at the drag strip, 3240#, 1.38 60' on radials. I replaced it with a Strange S-60.
Not breaking balls here chief but I’m actually a little surprised you raced that car at that weight with that beast of a mill you have there under the hood. I wouldn’t try it unless it was 300lbs. lighter or more. How much power is the engine pumping out and what size slicks are you running?
