CNCDude,
Thanks very much for clearing up the camshaft information.
I found my copy of Leos 6 cylinder book and discovered I had highlited his brief discussion of the topic. I now understand exactly what he was trying to say.
I thought for a while that the lobe advance had something to do with the siamesed port.
I had figured out the part about the additional volume of the port and the port velocity/turbulence problem from fooling with my home made flow bench, but I guess I was trying to connect them in the wrong way.
In my experience, anything you spin real fast is going to twist or stretch.
Axles being my personal favorite ($#*&*&^^)
Timing chains and distributor gears are probably my next favorites, but for some reason a camshaft did not enter my mind.
My actual build plan is for a 320" 6000rpm 3 side draft carb torque monster, so port velocity and a lot of static compression is what I'm thinking.
The actual grind will (of course) depend on the flow numbers.
Thanks again for setting us straight on the lobe advance.
Regards, Wilbur
