Rear End
can only tell you what happened.... had a well built 904 with a rather mellow engine... was on the main drag in my town hit second under hard acceleration and bang sounded like a shotgun... limped to side and rear was in piece internally.... so yes it can happen and you say i abused the crap out of it... isnt that what street racing and drag racing does...? those many cycles of hard hits? good god.. lets remember thats what this sport is about to some of us.... gettting some power to the ground and if that doesnt abuse the rear then...
I didn't say it didn't happen, or that it couldn't be done.
You can break
anything. This goes for 8 3/4's and Dana's as well, people break them all the time. This is especially true if proper maintenance is ignored, or never checked. Who knows what happened to that 8.25" over the course of it's life? Did you ever pull it apart? Check tolerances and wear? These things don't last forever, and we're talking about 40+ year old parts now. A well maintained 8.25" is more than capable of handling the combination you described, a sub-300 hp 318 in what should be a relatively light car with street tires.
And street racing is for morons. Period. Yes, I've done it, and yes, I was being a moron at the time.
fine that use his advice go with an 8 1/4...... if they are so good then why do we use 8 3/4 and 60's.......... BECAUSE THEY TAKE THE ABUSE OF HORSEPOWER.
I don't know, why do people use nodular 8 3/4 cases? weld back braces on the housings? Why do people put aftermarket axles in their Dana 60's? Why do they even make Dana 70's if the 60's are so good?
It's simply a matter of application. 8 3/4's and Dana's break too. I never said the 8.25" was the
best option, I just said that it
was an option based on what the OP said his combo was going to be. In fact, I said the 8 3/4 would be the best option, and that an 8.25" could cause him trouble down the road with enough abuse.
