Wondering what I have. Engine block, never used.

[tauro]

Would appreciate all of your expertise in identifying this. Tried searching online, and on the site, and with all of the identifiers for engine blocks and fakes and what not, its hard for me to pinpoint this to be something real or not.













Thank you for any help!

Looks to be a 427 block with the cross bolt main caps and screw in freeze plugs.
What's the casting #'s? Something like C5AE-H??

[tauro]

Ill have to look tmorow for that, where should I be looking?


*edit
There is quit a bit of rust on this thing.

Just looks like a big Boat Anchor to me! It looks like a 427 Side Oiler, maybe a service block? Where did you find that old bird? Are you going to use it? I've got the top end parts to make a nice motor but no block. Like others have said, check the bore dia. It doesn't look to have been used and I've seen a lot of NOS 427 blocks that look like yours. The first time you rebuild one all those paint markings come off. It looks to be in good shape. They've actually come down in prices lately with the availability of the new Genesis blocks. Hopes this helps some. Share the story with us, it's gotta be good.

The ribbing on the side would indicate it's a late 60's block, 67 or later I would guess. Most likely an "over the counter" replacement type 427 side oiler block. The oil galley screw in plug in the lifter valley also indicates a later 60's block that can run either solid or hydraulic lifters. The early blocks were ONLY solid lifters. The cross bolt mains say side oiler, as do the screw in freeze plugs. Over the counter blocks did not have typical casting dates, like C7AE or whatever. The date code clock like symbol is a bit complex to "read" but you will find it under or near the oil filter area (I think thats where it is...).

Just a guess now, but I would think the paint marks on the block may well be original factory stuff and indicate the block has never been assembled.

Any single one of the above items may or may not be found on some "ordinary" block, but the presence of all these items on a single block strongly point to a side oiler. The Coup de Grace would the bore measurment, that should nail it! A potentially VERY nice and rare find, me want...

Hello Tauro, Sent you a PM. Thanks, Matt

TAURO Micking the bore would be the first thing to do. What is the black line in picture #3 along the camshaft tunnel on the back of the block? It looks like a crack. I agree with the service block replacement. Does it really matter what year it is? It's a good find. If you are going to store it for a while, spary it with WD-40 and bag it. You need to stop the rust both inside and out side of the block. Rick L.

-Are the huge plugs the main thing that indicates its a 427 side oiler? I have seen the same ribbing on the 428 CJ engines, but i dont remember plugs that large.

-I dont see a black line in pictures 3, just thread sealant that drooled down from a plug and a shadow.

-Dont spray it with WD-40 if you plan on storing it. Over time, WD-40 will glaze and turn into something that looks like a peeling polyurethane coat.

I found Aerokroil from Kano Lab. in a spray can to be the best. We can buy at some of the part stores or supply houses.

its a service block for sure.....if the bores are 4.236 its a 427 side oiler.
will probably have no casting number other than casting date code.
that will be by the oil adapter mount. this will tell you what year it is.
the service blocks are usually from 1969 to 1974 ish....

I know a man in California who has a brand new complete 1960's 427 Side-oiler stored for a Cobra project. He has been waiting to build his dream car for over 30 years! Talk about sticking to a dream...

The crack is on the left side and follows nicely along the contour of the block. At first glance it looks like a shadow. It is non-structural and could be welded (I think). Maybe it is a shadow, . . . can't be sure.

Looks like a 390 or 428 block converted to cross-bolt. It doesn't have the correct bosses for factory cross bolts.

Looks like a shadow to me. It's very dark and distinct and looks like a crack, but there are two other shadow lines on the same side that are just as sharp and dark.
I vote shadow.

[BBQCYCLEWERKES]

Its a side oiler block for sure. Only came as a 427. The ribbing on the side indicates a warranty service block from what I remember. Looks like the block is cracked at the cam plug though. Is that a shadow or a crack?

Note the bulging area running vertically below the blue splat with three hex plugs in it. THAT is the internal oiling galley that makes your block a 427 "side oiler." I'm buying if you are selling.

What is that welding that runs along the top seam on the last picture above? It then goes off at an angle?? Is welding on a block normal?????
