    Your M20 with a 3.73 is equivalent to a 4.25 in a close ration M21 or M22. If you're using a BB Chevy, you've got enough HP and torque that you don't need the narrower spread.

    227

    Thats what I figured, I'll have enough torque and a wide powerband to work well with the wide ratio. A hot 327 might need the m21 or m22, or maybe an LS6 454. Have you seen the cam specs of those? 264 duration @.050?
