    I’ll be building a 302 SBF into a 331 stroker.
    I want this engine to have 8,000 rpm capabilities were it’ll be reaching making max HP in the upper 7s.

    YourUltra Dirt crank # UJE01@UD looks lightened for my needs.
    What connecting rods do you offer that are also lightened and can handle high rpms?
    Do your rods use pressed or full flowing pins?
    Do you offer pistons for my choice of compression?

    Whose or what flywheel and damper/balancer would you recommend that works best with your crank & rods with balance considerations?

    do you sell direct or thru summitt etc?
