    Where’s the best place to order a new rotating assembly from. Want to go to a different combo after junking my last block.

    Yes Hemi. Moved to short deck blocks now and wanting to go 481 cubes with 4.375” bore and 4” stroke. Would like to use a 6.8” rod. Was hoping to be able to find somewhere that could order the whole lot in one go and check to see if it will all work together without problems.

    Still can’t get any answers. I’ve never had this much trouble trying to get parts sorted. I guess it’s the problem with having old heads and blocks.

    It's a process getting things right for older stuff, much less one-off combinations.

    I have some 4.375 part numbers that would either work with a 6.755 or 6.775 rod length. That would be roughly 10.5 to 11:1 ish on compression. I need to double check the part number but I know where one of those part numbers are in in stock.

    Thanks Will. I’ve got old 10 bolt fuel heads that use 1/2 head studs, 2.375” intake and 2” exhaust valves chambers are around 175cc. I have some Arias pistons but they are that old of a number on the piston that Arias don’t have a record of them anymore.

    Arias # 1530212
    1.428CH 81cc dome for 176 head 12.2 COMP w/.050 gasket ,.. if you used a 6.800 rod you would be -.003 out of hole if you use a 6.775 rod as Will mentioned you Would be .042 in the hole or deck clearence.
    Also Venolia makes the piston for the 176cc head #132314 but would need a 6.885 rod as the
    comp height is 1.370
