    Molnar connecting rods RTH4724CJB3-A

    Anyone tried the Molnar connecting rods?4340 steel billet H beam connecting rods with special Molnar Technologies proprietary designed ARP2000 material cap screws.
    Weight 460 grams
    Any Issues with the stock crankshaft if connecting rods are lighter/stronger with oversized pistons, perhaps lighter as well. (Mossner)?

    When you change the weight of the rotating assembly you should get it re-balanced.
    I’ve heard of a few using the Molnar rods, but the rod bolts were smaller 5/16”, vs the OEM 3/8” bolts.

    Hey, thank you for the input!
    We've been getting input that as long as the new individual piston weights are identical to each other and the same for the connecting rods that its fine. Its the crankshaft that has to be properly balanced, hopefully from factory. Main bearings on the tear down shows no balance issues, hardly any wear.
    The bolts are listed to be 3/8" ARP2000 and the Molnar connecting rods are ready to go with stock pin, journal, bearings.
