One of the things I have learned so far in this very informative thread is that a 60mm cam core is preferable when building one of these beasts.
Having no experience myself, can you also do a +.250" raised cam along with the 60mm cam?
If so, how large of a stroke would be practical to run?
I'm thinking a big cube, reliable, bracket / Dragweek type deal.
Based on the pad in the block the cam gets machined into, I would think the raised cam is almost required to have the tunnel bored out to 60mm, just looking at my Callies block, there would not be a lot of material on the bottom if you machined a block with the cam in the standard location....I could be wrong, but seems like it would be thin.
