    19mm Gudgeon pin rods and standard pistons

    I have a set of forged rods, with the 19mm wrist pins, and a set of standard pistons to suit. While i got these at a decent price im left wondering whether i should have waited and got some of the 20mm pinned rods. The pistons are standard units and came attached to the rods. Can anyone...

    Rods - 19mm or 20mm??

    Hi all I have done a search but no results! Can anyone tell me what size wristpins are on the AYP block... 19 or 20mm? Also is it true if you change just the Rods then 400hp is possible with OEM pistons?? Many thanks in advance! p.s.... AYP Polo Project thread soon to come!
