Um, I don't think 230 HP, but it could be 230 Cu. In.. Based on the height of the side cover it could be a 194, 230 or 250 Cu. In., but that really wasn't your question. Chevy started that series 6-banger in '63 if I'm not mistaken. I don't know anything about date codes, but could the D175 have something to do with it perhaps being April '75 casting date? That would be awefully simple, but who knows? Lynn
Rear sump so its not a 194. It's a 230 or 250. There should be a stamped number next to the distributor hole. That will tell which. Also If i remember right the 230 had flat top pistons and 250 had dished pistons. Might be able to see in the plug hole and tell that way.
As stated above, it is a 230 or a 250 cu in. Depending on what you wish to do with the engine, it has the advantage of being able to mount later year standard transmissions or a TH350 or later automatic without having to purchase an adapter. I don't know about the later engines, but on the earlier 6 bangers, the stampings under the distributor would be helpful. Bob
Yup, 230 or 250. Probably late 70's. If you have the intake manifold, it's way different than the earlier ones. I think these were discontinued in 1983? Maybe it was 1980 or 1981. Good budget engine. There is speed equipment available.
The casting date code is April 17, 1965 (or 75 or 85), but we know it's 65 because it has the early valve cover, does not have a 3 letter suffix code, etc. Desireability...we have no clue what's inside there. Old, worn out, empty, rebuilt, who knows?
Not much With nothing on it, and no clue if it’s complete internally or if it’s even rebuildable. it looks clean what’s with the “ display only “ sticker. for $50 bucks it might be worth a gamble , at least you’ll get your money back in s**** if it’s s****. Cool engine just not big bucks cool.
I agree 230 or 250. I ran a 250 in a '62 C10, it was a strong and dependable motor. basically stock with HEI, split exhaust and a Weber carb. Almost forgot, a S10 T5 five speed trans.!
With what is said on the rocker arm cover I’m thinking it’s a display engine for Sears, Pep Boys, Western Auto, etc or similar store. Supplied buy the builder to be in a showroom. Probably not much in it and a cracked block. Does show a crankshaft but I’m guessing nothing but a shell. We had them in the 60’s when I worked in a Sears auto center. But I could be wrong and often am.....
66 was the first year for the 250, correct? April 65 should be a 230. Usable cores bring $50-150 around here depending on how much is there.
Right! That's what I was thinking about when I mentioned the intake manifold differences. I forgot they were actually part of the head. Big difference.
$50.00 just for the chance to tear it down and see what you got. It has to be a 230. Not worth fixing if it needs a head or the block is damaged. They are still being discarded for small blocks and LS conversions. You can buy one running for $300-$600
Display only may mean that it doesn't have any guts in it. One that one time hung on an engine stand out in the showroom to promote either the six cylinder at a dealer or promote rebuilt engines at a parts house. as far as I know the only way to check the difference between a 230 and 250 is the stroke. Plus a stamped serial number on the pad next to the distributor . If that reads FM it's a 65 230 that had a powerglide behind it. 1958-65 Chevrolet full size Engine Suffix codes (348-409.com) It's a total pig in a poke and I'd only pay what I was willing to gamble in case it was total s**** iron when you opened it up. I don't think offering 20 or 25 bucks is out of line here if even that. Maybe even offer ten and tell tell them you will go ten with no whining if it is junk. As others said, 230 and 250 sixes that run and drive that get pulled out are usually dirt cheap most of the time.
There's another later style six cylinder Chevrolet/GM engine it could be that's often overlooked. The 215 that was used in Oldsmobile's and Pontiac's of the early/mid 60's. Same block as the 194, 230, 250. I think the 230's were the only ones with a forged crankshaft and used 283 pistons, with 4 valve reliefs and flat top pistons. All 250's had dished pistons, so looking into the cylinder with a bore-scope could tell what it is. Based on the valve cover, with the Chevrolet script and twist in oil fill, I'm going to say 230.

Since sitting open spark plug holes, probably has rust in cylinders. Can you look in ports and even see if it has valves? Can you pull the valve cover or one of the side covers? That would tell a lot, with the additional peek into the cylinders through plug holes. Sent from my SM-G950U using The H.A.M.B. mobile app
Most of the display engines i saw were a bare block, crank (to hold a balancer) bare heads, and tinwork. Might not even have pistons, rods, cam, pushrods, Etc.... If you can't see it from the outside, it wasn't there. Saved weight on shipping, time on "building".
