489 vs. 741

I'd like to see the guys that have actually sheared a pinion off any 8 3/4 post their combos and when (roughly) it happened. I've never done it. Nobody I've known in 30+ years has told me they did it. ...And that's C bodies, nitroused big blocks on slicks, etc. I've seen axles twist, housings bend, driveshafts shear... I've never heard of a pinion shearing.

OP - The 273 stick cars had 7 1/4s in them and lived on the street and some track. I wouldn't sweat it.
