I think this is where the problem started...
The port durations on the cub are Drag port spec out of the box. Sure.. you can drop the exhaust by decking the base.. but... now your putting more time, labor and $$$ into a already more expsensive setup. Porting is the heart of the motor.. You use timing and compression to compliment the porting.
Drag ported cylinders sacrafice bottom end.. (as stated above) Why build a motor with less bottom end just to try and add it back with pipes, timing and compression?
Like RIPPEN said.. And I agree, I think this is what most of us are trying to say.
"I think the simple fact that Dave is trying to make is that a stock cyl ported 4mill remotly set up right can run up to what your getting out of a "piped down" cub.. "
On a side note.. I've heard a rumor.. not sure if there is any truth to this or not.. but.. I heard that Dan hull AKA A&S racing.. Helped design the port layout on the cubs with Calvin. Anyone who knows who Dan Hull is knows what his main goal is.....
