I'm getting a Lock-right posi differential for the 12 bolt. I got a pretty good deal on ebay for it. The advantage to this style is cost and ease of installation. You don't have to remove the carrier, just the spider gears from the open diff, and slide the axles out a bit. Install the posi in the carrier and slide the axles back in. It's a locker type too, not limited slip. So the price of the unit is less than a carrier type posi and you save money on the installation costs.

I'm also rebuilding a 350 shortblock for my jimmy project. The 4 bolt main 350 that is in the jimmy will probably be built for this project. I've always wanted to build a stroker, but might just settle for a very stout 350, vortec or aftermarket heads and a shot of NOS for a trip down the local 1/8 mile.
