    I was finally able to act fast enough to a market place add to score an NV3500. Just as a caution, Iíll drop it off at the transmission shop to have them go through it.

    Let the fun begin I guess. I have most of the parts to get the engine swap started. This weekend, I plan to pull the little V6 out, and prep the frame for the new engine. I ordered a smaller oil pan for the big block (5 quart vs 7 quart on it now) which will limit the amount of notching I need to do to the front crossmember.
    I have the new flywheel and clutch set up to match the NV 3500 to the big block.
    Motor mounts I’m going with low profile weld in mounts, the idea is to keep the motor as low as possible, which will save room in the firewall area.
    Ordered a special radiator made specific for these types of conversions. It’s all aluminum, with an offset filler neck that allows you to put the radiator inside the radiator support vs to the inside. That will allow room for a standard water pump and accessories.

    The breakdown of the engine has started. I have most parts needed already, just need to disassemble it, send the heads to the machine shop and put it back together. I have no plans to touch the bottom end, it ran strong and has some decent components stock. I have a complete new valve train, one of the comp came complete kits. Timing gears, cam, lifters, valves, valve springs/retainers , etc

    Some decent progress, I placed an add on FB marketplace for the original V6, the guy came by yesterday to hear it run, pulled it out this morning, sold already.
    Took advantage of the day off and set the replacement engine in. I still have to cut front crossmember even with the new oil pan, while it fits, if the engine was an inch lower, it would make a big difference with exhaust clearance.

    Pretty amazed that the stock manifolds fit with minimal modifications. The drivers side, thereís 2 mods I need to do to make it work. First is grind a small tab off the upper control arm, 2nd is I need to move the steering column over 1Ē towards the outside.

    Passenger side is the same thing with the upper control arm tabs, but I also have to modify the firewall a bit to get the exhaust pipes on.

    Everything Iíve read says the stock manifolds flow pretty good for what they are and can flow effectively upto 450hp. If I ever get the itch for more power, Iíll have a set of headers made for it.

    Still test fitting everything, the engine and transmission are bolted in place where they need to be. The V6 frame motor mount pads worked perfectly with the Advanced Adapters v8 motor mount plates, so that saved me a lot of time.
