And both of you had 500hp Bigblocks and slicks correct?



With an actual 500 HP and sticky slicks, and if the truck actually gets traction, the 18 spline 833 will be at its limits. Without traction? The OD will do OK right up to the point you get hooked up.

With a little (or a lot of) effort, I could and did break nearly everything. The point was, the aluminum case OD takes nearly as much abuse as the standard issue iron 833, right up until you pound the case away at the shaft bushings.

The right small block with traction will cause more damage then a big block without traction. Given traction, the teeth on the gears are going to break whenever they feel the need to break. Gene
