Hi Eric - a rod bearing burned up and cracked my moldex crank, I'm ordering a new custom billet fro m Bryant and thought about a couple custom mods, namely having them put a chrysler 8 bolt rear flange and doing a double keyway BBC snout. I can handle resealing the snout, but I'm not sure about the timing gear and chain. I'm curious if you've done this and how you made it work, I wanted to stay away from a gear drive. Thanks Dave
