He sure explains things very well. The pushrods are wild. I don't think tunnel port heads will accommodate those through the intake tubes.

This takes me back to fun times!  I learned a lot of the same lessons spinning up that cammer head.  More spring is not always your friend, and you want to set the full open coil clearance pretty tight to keep things under control  :D.

That is a wicked cool engine.  With that much piston speed, I imagine it can't spend very much time at those stratospheric revs.

Great post with so much detail. Still amazed a 600+CID engine can rev that high and not toss rods out!
