    been sitting in the pasture near the barn. Possible mice. I know rats used to build on top of the engine. Hesitant on opening it up.

    One good thing about those old carbureted engines is that it only takes 3-4 wires to make it fire up and less than 6 wires to make it run and charge the battery.
    Rest of the stuff is lights and ac and gauges.

    We had let an old Ford truck sit for over a decade near a barn under a tree.NO rats!
    It actually fired up with some gas poured down the carb and a good battery.
    Lifters clattered until it sucked some oil up and it ran on the15 year old gas that was in it.

    Tires were buried in the soil up to the rims from sitting so long but that old 4X4 pulled right out of it.

    390" with a 2 barrel and granny 4 speed.
    I say pop the hood and take a look. I always loved my Oldsmobiles.
    I had a bunch of them engines 350's 455's and 403 engines.

    is the 403 worth messing with? Lots of negatives around the internet. My dad always said it was a fast motor. But it’s still a small block right?

    The 403 is fine unless you want to go really quick and turn a lot of RPM.
    Some of those later Oldsmobile engines 350 and 403's had scalloped main webs and did not like a lot of RPM. If you revved too much it would destroy the main bearings and Block or main saddle flex was the culprit.

    But under 5500rpm and you are golden for 100,000+ miles easily on a cheap rebuild.
    Stick a 268H cam into an Olds and you will be amazed at the power.
    Couple that with some quick bowl porting of the heads and a quicker timing curve and put the hurt on many 350" chevy engines.

    That was the course of action decades ago.
    It still does well today.
