Rear end swap ideas.. (Purists need not enter)

The 12 bolt is stronger, but creates far more parasitic drag. The 12 bolt uses an 8.875" ring gear and the pinion diameter is 1.625". The S10 rear end is of the 8.5" and variety, built like a brick out house. It carries the 8.5" ring gear and shares the 1.625" pinion with its 12 bolt brother, mine has a lightweight spool, 4.88 gears, C clip eliminators to prevent the dreaded 10 bolt shuffle, 30 spline axles, and a girdled cover to help with the carrier cap distortion issues. This rear end was under my 49 ford sedan behind a dart headed 406" sbc and a jerico 4 speed, it was repeatedly kicked in the face by 4500 rpm clutch drops and two stages of spray, so I don't think the wheezy 318 is going to break it. I'm looking at cost effectiveness, it's free and I don't have to find, build, cut, weld then drive. I can simply weld and drive since its already stripped of its perches and my chop saw can handle any driveshaft issues.
