Can a 8.25 hold up under a stock 440 or is that a broken axle waiting to happen? Trying to figure my options

it's always a matter of power/torque of the engine and the wt of the vehicle. I've known a 8.25 lose it's spider gears behind a stock 318 tbi in a Ramcharger...and I've abused the living heck out of a suregripped 8.25 behind a hot 360 in a valiant...and it lived just fine.

I say go with it...if it breaks, upgrade then

the 440 swap in my satellite was done way before my time, but i've had the car for 8 years now and i've had no problems with the rear axle...and i'm not real nice to it either

Cool, thanks guys. I will probably just keep the 8.25 untill something breaks then, lol. I am gonna do the ZJ Grand Cherokee disc brake upgrade on it then, and I can reuse those parts on the 8.75 should the 8.25 break.

I would add ....depends on the gear ratio. LOTS of HOESpower and a short gear ..... you might get into trouble.

Mine likes to spider crack the adjusters even on street tires. Twice I've had to replace them. I would start working on plan "B" & run the 8 1/4" till it grenades.

Have one in my 69 B'cuda with a 470" BB.3:73 gear 4spd. Seems to hold up OK in my street car....I WON'T put slicks on it though!!

just think of the axle snapping,then wheel with axle comeing out,then the side of the bed and wheelwell that is perfect with fresh paint and all the work it took to get it that way!.....just before you launch it every time and you will baby that thing till you have plan "B" built to bullet proof specs...then stress test it

there is a reason they made a 10 bolt,12 bolt,8 3/4,D-60
