Standard bore Hemi block, one main web crack in the #2 saddle across the oil hole, looks to go up to the cam journal. What would you do with it?

What can be done with this block?

Wellll...

If it was for a numbers matching one of hardly any, E-body convertible or wing car 4 spd type trailer queen, I might consider building it to stone stock specs with whatever used parts I had with new rings and bearings and go. It would likely run a long time just on and off the trailer.

I have no clue if there is a reliable procedure to mitigate the crack damage. I think any procedure would be at best.

If it is just a garden variety VIN or the car is long gone I'd say it's good for a static display.

If you sell with full disclosure etc, I think you would have to be VERY careful who you sold to as the disclosure might not follow it to the next owner.

I have one cracked in the same journal - not quite as bad as yours - waiting for an evaluation right now.

I wouldn't worry about disclosure issues as you can see it easily in the photo-just write it down in the bill of sale and have it notarized.

It definitely makes a difference what the intended final use is.

For a race engine, it's a door stop.

For a restoration or stock type of rebuild, a good welder could fix it and then it could be machined and used.

Anything can be sold (with full disclosure) but asking/sales price reflects saleability.

A restoration only. After being welded up and re-machined.

Just a block and you don't have the car with it?

If you have the car I'd say fix it, machine it, and build it with the goal to keep it with the car disclosing to any potential buyer that the engine was cracked and professionally repaired. It should not be raced IMO but I've seen some truly stitched-back-together 427 Ford side oiler blocks that had a mile of rod in them run fine in mild street applications (Cobra kit cars). Welding is a valid repair but where there's one crack, there's bound to be more you may not be able to see.

If you don't have the car to go with it you have two choices as I see it:
1. Put money into it to have it welded and then remachine it all, then convince the buyer it's fine.
2. sell it "as is" and don;t waste time or sleep over it.

Personally and as a business - I'd go #2. There are lots of instances where raeally bad blocks were fixed. But the liability belongs to the one that fixes it.


Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

If it goes in an e body convertible or a 4 speed Superbird there are people that can fix it. Otherwise...

How long is the crack? If it is 1/2 inch or less I would have it ground out and cast iron welded and aligned honed If it is longer or goes up to the cam journal, sell it with full disclosure

It's a great block for a trailer queen or a cruisin' to the drive-in car.

After all, you can't just go out and buy a new one.......

In the late 60's/early 70's the fuel guys would run iron blocks until the crack got so bad that they had to chisle the main bearings out because the material would flow into the crack as it got bigger. I think the record for the Bob Banning team was 70 runs from an iron block on Nitro.

The moral is they ran cracked blocks many times. For a stock resto, I would look and see if it could be welded, or run as-is.

None of the above. Cut your losses ( and everyone else's ) and dump it. Selling it to someone else for "restoration purposes" only is BS. It's gonna get beat on and it will break - probably sooner than later.

Sell it to me for 100 bucks, I'll fix it and never look back. Can't believe some of these answers. What do you think they did with these blocks for thirty years before remaking them.

He says it's cracked to the cam tunnel. In higher HP race motor you would look back.........after you ran over the crank........LOL!!!

had one in the 80s did the exact same thing,all the way to the cam tunnel.bad situation to be in.obviously a flaw in the casting.there are shops that would weld it.get some cracked heads and build a nice garage display,or build a coffee table.otherwise you would most likely be afraid to start it and possible destroy the other 15 grand worth of parts....

For your own use in a cruiser or restoration, lock-n-stitch pin it. Have it line bored/honed, machine and sleeve the oil hole to the cam journal, hone cam journal(s), and green Loctite that cam bearing for good measure when installing them. Build stock or fairly mild and enjoy. Race engine, find another one to start with! Just my

Yeah, It's got a hemi. Its cracked, but it has a Hemi!

Nobody has mentioned getting an opinion from a good diesel welding service. I would give that a try. Any welder that can keep diesel parts alive ought to be able to tell you if he can fix it and how strong it will be when done.

This is an interesting thread. I'm not going to comment on what I would do, because there would fifty guys pop up and tell me why I'm full of it.

So, I'll just say this. I've been racing Hemis since 1969, and there was a long period (maybe twenty years) where nothing, blocks,etc. was available. If a lot of the guys who post here could see what we raced in those days....how we salvaged this stuff, the condition some of it was in, they'd be absolutely appalled. And, a lot of it went real fast, and was reliable.

And, I'll tip you off on something.....a good bit of it is still racing. More than you think.
