ok. so the sterlings are prone to spinnin the diff housin on the axle tubes? that what you were talkin bout?

 

Weak points: The guys at Custom Differential note that the spline length on the yoke and pinion is insufficient. This can cause the yoke to wobble and move, causing wear on the pinion bearings, thus affecting preload. This leads to leakage through the splines and pinion seal. Ultimately, pinion bearing and ring-and-pinion failure loom. Towing or running 38-inch-diameter or larger tires with 4.10:1 or numerically higher ratios has also shown to contribute to failure. This is the result of the decreased pinion size of the higher ratios and the tendency of the pinion nut to loosen, causing the pinion teeth to break. Finally, running 38-inch-or-larger tires commonly causes excess spider-gear wear and failure, along with case failure. Custom Differentials has actually seen the case split in half when this occurs.
Fixes: You'll get longer splines by upgrading to the 2nd generation 10.25-inch ring-and-pinion. Switching to a three-spider gear setup will go a long way to address the other issues (see the information on the three-spider gear upgrade under the 10.50-inch "Hot Tips" section).
Hot tips: Apply silicone to the splines of the yoke before assembly to seal the yoke to the pinion shaft and stop lube leakage. Custom Differentials also notes that every time they rebuild a 1st-generation 10.25-inch axle using aftermarket parts, it automatically includes an upgrade to the 2nd-generation long pinion setup.

oh. hm. well i dont plan on usin that big of tires. lol. and i dont drive my truck all that hard either.

 

I know absolutely nothing about making HP out of these motors... but you don't see too many 460's or even 400's at the drag strip. Granted it takes a lot more money to do, but the 347 seems to be themotor to go fast in, yes?

On a side note.... I made 500whp (almost 600hp crank) in my 2.0l Subaru..... do I win the competition?

 

hope the other ' tard' you are referring to isn't me. lol the suspence is killing me

and 460/5 that avatar is awesome. gun control means hitting your target

 

someone remind me to unsubscribe to this thread... oh wait, just did.
