Engine casting numbers
I do have what I think is a Date code on the bottom right hand side
(Passenger) bottom end, numbers that I see are 4 B 28 with a Arrowhead pointer at The letter D ( I think the D means Day shift) . any Idea what date the block was made from 4 B 28
Regards, Hulou

Yeah should say B 28 4.
On the same area towards the back of the block, but on the other side there should be a block number, should be something like 3782870 or 3737739. Something like that.

well, the intake is from a 1964 or possibly 65 327/250 hp. The carb is from a 1962 327/250 hp. The block was cast in 1964 as we determined, and IF its from a Corvette as the other parts appear to be, its a 327.
However, since the pad #s are gone I know of no way of verifying that without opening it up.
The casting number may help.
I'll check for the casting number today. I looked yesterday and couldn't see a number but I did see letters in that location behind the driver side valve cover as the attached picture, The casting# just said "GM" I didn't see any smaller numbers that you referred to?
Thanks

The pics are great! Tux's help is greatly appreciated.
Vetter Buyer Thank You! : My number/s does not look like your picture, I can See the "GM " like your "GM" but the Casting number number goes inside something, , I think maybe the flywheel hosuing or somethng. I can reach inside the opening and feel the Casting
number with my fingers the number per se is visible? I don't know what I have here, But My block number with the of the GM does not look like Yours? that all i can see is the "GM" letters
The engine runs good, but I don't really now what it is? I'll keep looking, maybe get some help from my buddies and pull the engine and go through it. It I can take a picture that you can see, I will send it along! Thanks for all your assist, Hugh

Here are some pics I took this am of my engine, I still trying to ID it
-No Egnine pad number infront right side? intake Manifold is @3844457 I think 64-65
-Card Carter #6-15 86
-Casting on bottom, Right side was 4 B 28 with arrow pointing to the D
- Exhaust Manifold is 374995 Left hand ( Think 58-63)
3750556 Right Hand
Flywheel housing #3742386
Attached here are a few pics, The pic with my fingure, I'm pointing to the GM (Cant see Number)on the rear of the Drivers side Valve cover.
Thank You for your asistance!!! any ideas? No body around where I live knows much about old Corvettes/283 egine or other wise.
My guess is this is a Chevy passenger car engine late 50's or 60s
I think he oil pan is a passenger car version
Regards, Hugh
That picture does look like the back of the block is oddly stepped down at that point..............
Your exhaust manifolds could be from either a 283 or a 327.
The left side should have seven digits, I think you left one out. I believe it should be 37499(6)5, which would be from a '58 to '63 283 or 327.
The right side 3750556 is from a '58 to '65 283 or 327.
Both are 2" nominal outlets.
Sorry this still hasn't narrowed it down any further!

I simply do not believe that engine does not have a number there.
Ok, I did leave out a number of the left side exhaust manifold the # I have on mine 3750556.
Last Pic. To the right of the oil canister. The orange part is the the back of the enginemaybe flywheel housing? behind the oil pan, where the "black" part , Transmission is bolted to.
On the "GM" Letters on the right rear of the Motor. I can't see any numbers next to the "GM" I think I can feel what may be enbossed number when I put my finguer into the space jsut to the right of where by finger nail is seen in the picture When I move the Blue plug wires out of the way the metal surface of the housing is Smooth, No Number are seen? How elas can I help on this ID? Thank You All,
Hugh
