Thanks for the reply guys. It's an 11:1 383. 060" over. 1st design stage 6 straight plug hand ported heads 2.14 1.81 valves with a 7.100 rod.
It does work well but of course every time I get asked about it I always hear about how old the cam design is.

I'm building a 406cid twin to this now and I have another dinosaur going in. Lol
