    I'm targeting DP class for my '73 2.0L and my motor is getting rebuilt. What's the largest piston/cylinders I can run and still be legal. Rules state...

    "The block may be rebored no more than 0.0472” (1.2 mm) over
    standard. US-produced six-cylinder and eight-cylinder engines
    may be rebored no more than 0.060” (1.52 mm) over standard.
    Alternate blocks which are of the same material and nominal dimensions
    as standard are allowed. Critical dimensions for piston
    engines are deck height, cylinder bore, cylinder spacing, vee angle,
    and distance from crank centerline to cam centerline. Critical
    dimensions for rotary engines are epitrochoidal curve, working
    chamber volume, and eccentric shaft location."

    The way I read it, I'm stuck with the OEM jugs - unless my math is wrong
