Good call nm9

Furthermore, specking out a bigger cam may not be the answer. It is the ICA that is important. The real, installed, intake closing point. A one size or maybe even a two size bigger cam (longer duration),can have the exact same, or very nearly the exact same, ICA if they tighten up the LDA and add the duration in the overlap period.

They made all this work in 1967. And with a .019 metal head gasket! Was it because the fuel was better quality than it is today? This build is not that complicated and not that far from the original 235 HP original commando release so I am having a hard time understanding all the concern. Not criticising, just want to learn a little something here!
