    I can't find either, but it's probably from 87-89. It seems anything with a castng starting with 14XXXXX is from that era. Same with the ARH suffix. anything even close was for an '89 350 or 305

    Here you go..

    14093638...350...87-95...2 or 4...Roller or flat tappet cam
    one-piece rear seal

    14102183...Late 350 TBI swirl port heads.

    Limited high performance head. The funky shape and swirl vane in the intake port promotes high swirl and turbulance but restrict high lift flow.

    Hope this Helps..

  13. Matt ..THAT'S IT MAN !!! got a HP rating ?? (yea it's a 9 not a 2 in the casting #)

    Thanks, Skip
