    Long stroke 535. they don't like to be buzzed high. Need real good heads to feed it, all aftermarket build also.

    When you have that much stroke and displacement, you don’t need the high rpms to make TQ/HP. That would be a great street engine!

    535 is an expensive build Bob.
    Mega torque is nice.
    Also very hard to hookup come battle time.
    4-link backhalf car.
    Hp there but not stellar.

    455 - 462 my favorite.

    Some guys happy.
    Lots of options.

    Also require Super Danger Zone Cams to perform No Prep Drag Race.
    Hotter than I prefer if you believe that.

    Some New Ram Air 5 HEADS out.
    I like .
    $20 K with headers to own.

    Eddy Eddelbrock Heads Pro Race ported a good option.

    Watched the 535 Vid Grump.
    No real smart running making pulls without the water pump turning.
    It's a Pump gas build.
    Can hear it.
    Revving up lazy.
    Soft cam.
    Actually made less Hp than I expected.

    Dodge shut it right down.

    Nick makes Fun Videos to watch.

    It has the D-port Edelbrock heads.
    Never seen them on a Dyno till tonight.
    A True low budget street engine.
    It's a little Flat tappet hydraulic cam.
    About 220 @ .050 lift.
    Looking at maybe a .510- .520 " lift cam only.
    Not sure of Lobe centerline but it's Super Loud.
    Maybe a 108.

    Vintage OFFENHAUSER Daul quad intake still works.
    A 50 year old design now.

    All Hp in by 4800 Rpm.
    I know it's a small cam.
    Stock Stamped steel rockers also.
