Good evening. I have a few engines that I need to get out of the way. Need to reclaim some space in the garage. Curious if I should just scrap them or If there may be any value to them.
One's SBC, casting #3970020, with Crank & pistons. As I gather it, should be 70-73 307 with 2 bolt mains. Sat outside without heads for a few years before I picked it up.
One is 454 from my 98 3500HD dually. Has crack in the deck close to lifter valley. Heads were reworked before we found the crack.
One is 440 Mopar. Casting #2536430-2. pretty sure 68-72 engine. Block with crank & pistons. Been sitting outdoors, (under shelter), for a few years when I picked it up.

Just curious if it's worthwhile putting them up for sale,(cheap), or should I get paid for their weight at the scrapyard.
I know the 454 heads are in good condition, but are they worth hanging on to, or selling? I can get the #'s from them in a day or 2.

Thanks.

Early 440 engines are getting kinda rare. I see complete cores selling for $300-$600. More if they're out of a motorhome/RV...

I don't think 440's are getting rare, but then again, I usually have at least half a dozen sitting around. I will not pay more than $300 for one, and it must be intake to pan for me to give that. The casting date should be on the side of the block, but that doesn't equate to the installation date. The top pad will tell you what year the engine was installed (A=1965, B=1966, C=1967, and so on.) If it has the narrow balancer (1" approximately), it's a forged crank motor. Anything wider, and it's a cast crank. Cast crank is worth less.

The 307 is just a 283 with a 327 crank.
