    I don't pretend to have as much information or expertise as Jerry or others about the current production 454's, but I'm pretty good at cut and paste .....I'd be looking for a Gen VI motor with any of these block casting numbers.....

    10237297...454.......96-up...4-bolt, Vortec 7400", "L-29" Gen.VI
    10237300...502.......96-up...4-bolt, Gen.VI, 4.466" bore
    12561357...454.......96-up...4-bolt, Gen.VI
    12561358...502...............4-bolt, Gen. VI

    Here's an article on a boneyard L-29 that picked up pretty good with just a cam and spring change....500+ dyno ft/lbs ain't no pooch......
