Thread: GM Engine?

six digits doesn't look like a GM part number

Some things don't add up here. The "Half engine" part is a term I've never heard, and why would a GM crated up engine have two Holleys and Edelbrock valve covers? To me a half engine would be a short block, whereas this one sounds like a complete pan to carb(s) engine. Do two Holleys even fit on top of a Chevy small block? I know they do on the crossrams, but.........

Very easy way to solve this. Take pictures, lots of pictures. Take the crate, the writing on it, what you can see of the engine, etc. Then we have something to validate what you are saying. Not that I am doubting what you are saying, but you are kinda new around here and we haven't had a chance to get to know you yet.

Post up those pictures, we're anxious to see this motor and try to help ID it for you.

Haha i think i worded my first post very poorly judging by the response of some of my new peers here on clubhotrod... first of all thank you for all of your posts...ill clarify what i meant a little bit now..

when i said "came with two holly 4 barrels and valve covers" i meant came with as in, sitting on the garage floor next to the crate ...i dont know why i even included that in the post it was completely irrelevent as far as what i was looking for in an answer....for all i know they could have been for one of his other cars....

second, ill try to get pics up as soon as possible... but yes the only thing on the crate was printed "General Motors"...im going to have to dive in and take pictures tomorrow if i can... its 1 AM here and i have work in 5 hours

the only thing i noticed from quickly peaking in was that it has a timing chain installed on it already and looks like complete heads up to where a manifold would go, but again i havent opened the crate completely yet in proper lighting, just my dark garage corner...

as for the number 396921... i searched and searched and havent been able to match it to any engine casting number on the net... so its probably some kind of stock/serial number... anyway, pictures will tell the rest... any other input def appreciated though, i will get the pics up asap! thanks again guys!

Ok, that clears it up somewhat. Post as many pictures of the whole deal as you can and we will have a better shot at figuring out what you have. Sorry to be skepical but sometimes one of those 12 year old kids in Nigeria or wherever gets bored and comes on a forum to have a little fun with the locals. We've had our legs pulled a few times when we offered sincere opinions and then we find out the poster was bogus.

Six digit GM part numbers are common for the pre70's era. In my small block book, there are six digit numbers listed for partial engines (a partial engine has a block, crank, cam, timing chain, rods and pistons and is commonly called a short block) ( a fitted block has the block and pistons).

For instance, 376372 is a 62-67 partial engine with a hydraulic cam.

Pop the plastic and identify the engine. Grab a casting number and the engine code and we can identify it.

That's what I thought, and considering how long it's been in the garage I wouldn't doubt if it was pre 70. I'm sure half engine would be similar to "partial engine". I can't wait to get the castings now, but I'm still at work I'm actually on my phone right now, so tonight I'll try to get the info. I'll include pics and model #'s of the carbs also, which are still brand new in plastic in the original boxes. Thanks for doing the research!

Oh Don - that was funny. I can see it all now:

Most Honorable Hot Rodder.. I am the barrister for the late Count Forrest Columbia Winston Ohmart who has died and left in my care a garage with the following - a 1940 Ford Deluxe, 1963 split-window Corvette, a 1969 Z-28 and a 1970 SS454 Chevelle. All are original, with numbers matching and under 1,000 miles.

If you would be so kind as to send to me your home address and I would then begin the process to crate and ship these fine automobiles to your house. I would also be so bold to ask for your bank account number, routing information and your Visa and Mastercard numbers to guarantee prompt and correct identification of you as the only worthy surviving ancestor who is very much deserving to receive these cars. My fee has been graciously covered by the 2 mjillion US dollars that has been set aside for processing of these tresurers.

Your kindly response is most desired to assure the happiness of the dearly departed one.

Sincerely -Majuhobia Nigerauka III, Barrister

Oops - sorry to hijack the thread, but I just couldn't resist

Regards All,
