Is a Big Cub 18* Open Motor enough

Matt,
There are no magic numbers but there are some numbers that you need to be close on.Carburetor cfm,intake manifold size,intake runner cc,camshaft lift and duration at. 050 and. 200,rocker arm ratio,compression ratio,rod to stroke ratio are all important but they differ for different cubic inches.

If you want to put together something real common like a 406 with 6" rods and a common set of 23 degree heads, pretty much any decent cam guy can sell you the right cam.
