    Do you mean L67 vs L32? I think the L36 is the naturally aspirated block and if so Im not sure about that with the compression they have. I could be wrong about that though.

    If it is between l67 and L32, l32 pistons are moly-coated, and connecting rods are powder-forged I believe

    l67/32=8.5:1 iirc
    l36/26=9.4:1 iirc


    that is the only difference. o, and all 05+ and some 04's have powdered metal rods, which are batter then cast, but not as good a forged.

    ^^^ His L26 block probably has the powdered metal rods, which would make it stronger than the L36 rods.

    The blocks are identical, but the L36 has different rods and pistons. The L36 internals are a little lighter. A well prepped L36 can handle 350-400hp.

    Are the L26 internals stronger ?

    Because my buddy is DDing his L26 Turbo with 400whp on 13psi.... now he's on 16 PSI.....
