A very good buddy of mine has this engine for sale. Can anybody decipher what it is? I'm leaning toward buying it if its a 327.

Stamped on engine pad: 18S111983 VO915DR

And which heads are these?
Head casting # 3911032 Date Code: I 13 7
Block date code looks like I 6 7
Block casting # 3914636
Intake casting # 3919803 (Quadrajet manifold)
Intake Date Code F 27 7

The engine looks like its never been disassembled but I can't turn it over with a pry bar on the flywheel. No rods sticking out of the block tho!

I'll post some pictures tomorrow.

Notes in RED... if it is cheap enough, then you can bore it out to whatever you want it to be. Not being able to turn it with a pry bar, might be the deal killer. Have you tried to remove the plugs, squirting some oil in, and then try to turning it over?

It's not a 327. Its missing 20 cubic inches. Good thing you asked.

Just out of curiosity, how much would the bore need to be enlarged to make a 307 into a 327?

And would the crank and conn rods be the same for 307/327?

It would need to be bored .125 , my 327 in my '62 started out as a 307 , had it sonic tested and came back good to go , so bored it to 4 inch , brought a set of standard 327 cast flat top pistons , i had a set of 1991 corvette l98 heads , already had a mild cam , really perky ,T5 transmission , revs to around 6500 quite easily and good on gas

Or... if you want to get into some machine work.... start with a 327 block and make a 383 out of it

Thanks Cowfarmer. I will probably wait for a real 327 instead of making one. Not sure yet.

Why couldn't he make a 383 out of a 283 block?

I don't know, can you? Are the cylinder walls thick enough for the needed boring?

I wish either one of us was closer. I have a 64 327/250 motor that needs rebuild. I was going to redo it but thats probably not going to happen. Good luck with your search!👍

I did a google search for the question that I asked, and I found the answer in another ChevyTalk forum. Read all about it!!! Link

I saw that myself when I did a quick search earlier. The thread did not seem conclusive. It sounded like you could probably bore it, but the crank clearance might be an issue due to weakness in the block.

I have a 327 engine in my 64 that I had bored/stroked to 383 (line bored with 350 main caps to fit the stroker cranks commonly available), so I know it can be done with a 327 block. And I saw a few mentions of the 283 and 327 castings being the same (within our years of interest here).

It would make a great sleeper having a 283 with an extra 100 cubic inches Of course you would have to make some small compromises in perfectly original appearance, like 2-1/2 inch exhaust and the larger 327/300 radiator. I think there was a 283 variant with a 4 barrel, but probably not sized well for 383.

I think Speed-O-Motive, for a while, made small journal 383 rotating assemblies. Might have been someone else; it's been a while. Start with a small journal 327, bored .030 over; I can't see a 283 block going .155 over to 4.030 bore. There were a few companies making a 350 from a 283 in the 60's using a welded and reground crank.

There was a dual-quad option for 283's back in the day also. Buddy of mine had one for a short time in his '56 Vette. He soon blew the engine!!
