Ok, i know there is a sticky for this, but i guess im just not smart enough to figure it all out..

Can someone PLEASE help me SPEC a cam that puts me in the optimal DCR range.

cylindar head = 67cc

piston = 2cc VR

head geasget thicknes = .004

cylinder bore = 4.031

deck clearance = -.002

stroke = 4"

rod length 6.125


Just really need some cam specs to play with.. everything that i thought would put me in my range is only like a 6.75 DCR..

I know someone here is smarter than me at this, i need to tell the builder tomorrow what cam to slap in it, so any help would be awsome!!
