std cub/4 mill cub

[kawiking]

how much power diff is there between a std cub and a 4 mill cub ?

Quite a bit... a 4mil cub is a pretty potent race motor, i liked my 421 cub but and going with a stock stroke cub this time for my hill bike.

why not a 4- mill ??

I just didnt see the advantage of it quite yet, and Im running a 370 long rod crank in this cub so it should run well. More then power, for our shoots we have here setup is key.
