    Thank you


    The suburban was built with two other 4x4 square body trucks, the clutch pedal assembly came out of a 1984 k20 truck.

    Sand blasted the clutch pedal assembly and added some fresh paint. LOL no one will ever see it though.

    The hole for the floor shift was already notched from the factory as was the hole for the clutch shaft.

    The motor is a 1984 smog 454, has a mild cam, with the old school 290 heads.
    Cleaned up the heads and lapped the valves. Added new valve seals.

    Has a holley 750 with vacuum secondaries.

    Will likely never go off road with her, Too much time and labor invested. LOL

    Made the entire exhaust system in house.
    3 inch off the collectors all the way out, Added a 3 inch cross over about mid way and Flow master mufflers at the tail end.

    How did you manage to do a big block 4x4 burban when the factory couldn’t do it? Awesome!

    I meant it sarcastically because I never could understand why they didn’t offer that combo from the factory. It is a nice combo to have for sure
