What’s up guys,

Im looking at this engine block and parts but I’m not sure about all the numbers and stuff. Does anyone know what this is worth? I’m looking at purchasing it.

here’s some photos.

It's an antique 67 or 68 396 cubic inch BBC. Probably a 325 or 350 HP.
If you're planning to put it in a S10 there are lighter better choices than a 52 year old BBC.
Fully assembled they're heavy unless you plan to buy expensive aluminum heads for it.
The cost of those heads would buy you a nice 5.3, 5.7, or 6.0 LS engine that is lighter, more powerful, and more efficient.

Try to get the stamped number sequence from the front passenger deck surface.
If you find the matching car, the owner may pay a significant amount for their correct engine.

It is not a desirable block for performance use, but still worth looking into.

@Lonnie P the guy want 500 for the block, crank, and the orange heads. I don’t think it’s worth it in hopes of finding the dude with the matching car. Not to mention the he could be the guy with the matching car. Haha. I could see hot that could pay off tho. Thanks for the input

If you can't find a good 454 core where you're located, come on down!

Small bore shrouds valves and inhibits flow. When GM made the "next" block, bore was 4.250". Combine that with the crank in the one you're looking at makes a 427, the most "legendary" engine Chevy ever built.

302 was a better motor

^ sure not going to get any argument from me!
A buddy in high school had a '69 Z28. It was hard for me to learn how to drive because it took so much throttle to get going with the big cam.
But man, oh man, that thing would fly when it was revved.
It didn't have much trouble with 396's but a well tuned 427 or 454 would wipe up the streets with a 302, the torque just ain't there.
Once wrenchers figured out that a big block could rev just about as high as a 302, everything changed. And bigger bores with heavier pistons didn't affect it as much as most thought, including myself. Once you've been around a 565 that shifts at 7500, the lightbulb goes on above your head and your view of the world changes. At least mine has!
