    Started a new engine install. Have not run it yet, I'm at work for the next two weeks so will get to that when I get back home.

    Its a 1970 SP Code 350 4bbl. Been completely rebuilt and balanced.

    Looks good and can't wait hear it run.

    Old engine.

    Cool swap man. Did ya build it to be a low end torque monster? Have a good one.

    By definition, SBB are torque monsters compared to any of the rest of the GM 350's, but that being said, yes, I believe it should still be pretty good. Put a 268 cam in it which should bring on the power lower in the RPM's especially since its in a 4x4.

    Well, finally got it started and broke in late last night. Had a small issue with a carb gasket. Swapped for the ones that came with the Mr. Gasket spacer and leak sealed right up. Fired up on first attempt. Ran at 2K for 20 minutes, then about another 20 at around 900-1k while the carb adjustments were completed and timing set. She got hot, but not bad, lost of paint and oils burning off. Then after another 10-15 minutes the idle was set and here's what we have..

    Hear it run here.

    SP code 70 motor is what I've put in my wagoneer with Fitech fi. You're going to love that engine.

    So far I love it. Only have about 300 miles so far. The really lopey idle is gone, it still sounds mean and lopes a little, but not like it first did. I hope the cam is OK. We broke it in properly, maybe its just the Carb needs more tuning as it breaks in and gets the Idle settled again. Hope that's all it is.

    If it runs smooth and the cam is probably alright. Fiddling with it and adjusting the idle circuits will calm one down a lot of times.

    Hey. Nice!!!
    We have a 73 J4000 with a 360 AMC that we want to put a Buick in. Was your Gladiator stock with a Buick 350? And is that the original transmission? It looks like an AMC bolt pattern bell housing.

    The TH400 trans. being installed is a "Nail" bolt pattern trans. This is want Jeep used way back when before they started using 727 Torque-flights.

    I like it. I have started a 350 Buick swap into a 89 Jeep Comanche.

    Nice truck. I had on and sold it. maybe get another one day. Noticed something bright orange on the front of the timing cover. Thought that was taboo on a Buick
