Love the idea of thinking out of the box and making your own stuff, but at this point why not just put a 5.6 with a painted block in it? [emoji1745] You can still use your adapter bellhousing. I have carved out a rear plate to fit over the rear main plate. I'm going to drill holes to roughly align with the dowel pin hole and install dowels, then re dial in the runout(I have it at .003+/-). I'll ten fill the holes with JB weld to keep them located in the plate. There are two holes that will also be drilled and countersunk in the plate with Allen heads into the alloy block trans holes. This is a 5.6 being prepped for my 4 speed in the drift car.
