    Molnar Rod Set New 1503 motor

    Have a brand new set of Molnar Rods comes with custom arp bolts. Fits 1503 motor, unsure if it can be used on a 300 motor.

    $480

    They can if you use a custom piston ONLY.The 1503 rod has a longer rod but shorter stroke 120mm rod.The 1630 "300" uses a shorter rod 115mm and a lot longer stroke which is 7mm but you can use the longer rod with the longer stroke and achieve dam near 1.75 r/s ratio which is PERFECT...good luck with sale.

    It means that with a longer rod you can reach more compression in the 300 platforms . Ciao Vale !

    Better rod/stroke ratio less wear on the bearing.

    Well run a longer rod with a 300 crank and stock piston and watch what happens.You have to have a custom piston if running a longer rod on a 300 crank....I was just answering his question is all guys no big deal.

    Its not that simple you have to modify the 215 rod as it is wider and the 300 rod is narrower sry forgot to mention that.
