Looks like you asked the right people.
You can ask this guy. He just bought a brand new one. Wyatt Earp builds them in Oklahoma from the original mold. He has put a step in the keel. Raised the "X" quite a bit and has found the sweet spot. Not sure if this one will bust 100 with a 496 and a 150 shot of spray.
