Best stroker combo?

Hp goal is what dictates cfm needed. Saying this cid or that cid needs x amount of cfm is only relative to an already targeted power goal. Cross section for rpm capability yes, however upping the cfm can give the similar results but the two are a lil different.

Gears. You want stroker torque? Put steep *** gears in the back with 'decent' heads and a cam that will use them.

Heads dictate hp, gears will make the torque with or without them though.
