a STOCK 340 will not break an 8.75 unless maybe it was a stick car, and you put slicks on it and gave it a 5500 RPM clutch drop at the track.
look at how many cars in the magazines are running strokers, hemi's, 5 spds, etc. with an 8.75 axle.
you'll be fine.

I'm glad you said unless it was a stick car because I broke one , not sure if it was a 741 or a 489 , but ring gear bolts came out ( factory built unit never opened up ) and broke one of the caps  ...

I broke an 8.75 with a stock Challenger 340 auto, 355's all stock 54,000 original miles, on 14 street tires, belted T/A's G60-14's........in fact put 2 rear ends in that car, blew the pinion on one, and broke,...Sheared off the driver's side axle splines......with just burnouts
also toasted the 8.75 in my 72 barracuda with a 318 auto!.......wheel hop during a brakestand broke the drivers side axle bearing, causing the axle tube to crack, plus the u joint exploded and I dropped the shaft big time!.....spit it right out!

I had a 741 in a circle burner(dirt) that twisted the splines enough to where we could barely get the yoke off. 360(2bbl 9-1 cr. class rules)  no drag race type starts but constant accel/decell but I wouldn't have any regrets using one for the street.
