    Wiseco forged replacement OMC 49.9 Mod-50 pistons are now available. They are improved versions of the #10908 previously supplied by the late Phil McDaniel. Designed for use with the Mod-50 or RD-series (40HP) “long” con rod, these pistons include a .120” top ring land, pre-machined boost and finger ports, plus hard anodized pin bores and fire dome. Each piston kit includes wrist pin & retainer clips and steel keystone rings. Size offerings include standard (3.000” bore), +.020”, +.030”, +.040”, and now +.050” oversize. Pricing is $135 each.

    Taking orders now. Please reply with your request. Thanks,

    Tim

    Breaking news: +.065” oversize Mod-50 replacement pistons now available!

    Wiseco just approved manufacture of +.065” oversize pistons for the 49.7 CI OMC loop triple. This means you can breathe new life into run-out or damaged +.040” blocks, creating a 51.9 CI monster! Bore sizes now available include: Standard, +.020”, +.030”, +.040”, +.050” and +.065”. Notes:

    1) The +0.065” piston is legal for APBA 850cc Mod and NBRA Super-E classes which share a maximum +0.070” bore size. Minor file fitting of +.065” piston rings required.
    2) Pistons require use of OMC Mod-50 (3/4” pin bore) or RD-Series 40 HP (5/8” pin bore) “long” connecting rods. “Skinny needle” wrist pin bearing conversion kits are required for the 5/8” pin bore RD-Series 40 HP connecting rods.
    3) The Mod-50 replacement piston includes a flat top fire dome design that requires use of the 70 HP service cylinder head with pocket style combustion chambers.

    Commitments through June 1 will be at the introductory price of $135/piston kit which includes the Wiseco forged aluminum piston with hard coat anodized pin bores & fire dome, wrist pin & retaining clips, and semi-keystone steel piston rings. So don’t delay; place your order now!

    Best of luck with your engine projects,

    Tim
