Thanks... Im planning on keeping the ZC, bump compression and possibly go carbureted.
My Brown Top's already on Yam R1 Carbs and is shooting for the magical 11:1 too. Bent a rod on just the carbs alone. So if you are going the hi comp route think about rods and oil pump(week spots on the D's), shot peen the rods at the very least and if you take it appart have the full rotational assembly balanced.
Very jealous btw, wish I could have a real ET, for now its only a dream
