Himes casting reapir in Indy is the best guy in the country--Fair/Honest and one of the most skilled fixers ever--I had a numbers 6 pack block that had tossed a rod on #1 destroyed the jug and blew a chunk that included the mounting ears off the side-- split the deck--I mean it was FUBARED! When he was done there was a wild look on the inside--but on the outside no one would ever know--he saved the unsavable--that was $1200 back in the mid 90's and I was glad to pay it Worth tripple that today I would think--Best guy you will ever deal with

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 Beep
Yeah, It's got a hemi. Its cracked, but it has a Hemi!
I second the Lock 'N Stitch method, and use in a stock/restoration build.

Himes is cheaper in long run to fix it RIGHT and go on with life those stitch pins and all are ok if you want to get out of Mexico City and get back to the states but are not a REAL fix--there are threads everywhere NO blocks--fix it right and be happy Hey--I had a state owned auction dodge PU with a 360 cast crank broke in two --it RAN --did not like it but would still take you to the store for beer run--lots of stuff will "work" but just do it right You may wind up with 2K -$2500 in it so what? that is a good day in Hemi world

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.
How True... my second block had more cracks than the Mona Lisa... but that's all that was available back then and were glad to have it! I have a block under my bench that is a ,73 over the counter block that is cracked thru the # 2 main much like the OP stated. no current plans but after the de rusting process I would run it ( all ready welded)

Resto or mild streeter, fine..............Race car, no
As far as what guys did back in the 60s and ran fast. FAST is a relative term. What so called "race" motors made for power and ran back then, is slow by todays standards.
How much faster is an A/Stock car now as compared to the 70s...........same parts, as far as block heads and most rules. They make WAY more power now.
You want to run a busted up factory block in your car, fine.........but if you were next to me, I would just hope it had a diaper on it. And some can call is BS all they want. Don't change the facts, that a repaired block is considerably weakened.
We just had to trash a $6000 alum block that was cracked the same way, that had several hundred runs on it. Could it have been welded, yes.....us use it, HELL no. Stuff fatigues, cracks and doesn't last forever.

First thing is to have the block magged to see how far and bad the crack is.We have seen and have repaired blocks similar.Some can be welded and tubed to seal the oil passage.It's tricky since the tube needs to be open to the cam and lifter galley.We just had a block come in that has a repair but shows a crack on the oppsite side of the hole. The hard part about any cast iron repair is where the weld and iron intergrate it becomes hard and is difficult to machine.Repairing is easy,machining becomes difficult but with the new process,s available a good skilled welder can repair most anything. If this block is a factory numbered block and is destine for a restoration project that must have(the correct,original part) then repair it.

The car it came from is said to be long gone. Just looking to possible repair ideas and potential costs associated with them to see if it makes sense to do anything with it.
For those of you who think the Lockstitch method would work (a method I think is a great option for fixing freeze cracks etc. on the outer surfaces of blocks, etc.), how the heck would you access the crack to drill the holes etc. to accomplish a repair in the main web areas with that method?..
Lock stich and other drill,screw or plug type of welding is great for non-structural,non -load areas but would not be a method for that repair,it would futher weaken a critical area.If the crack doesn't extend too far it would be a repair that cost aprox.$500+

I've had two blocks here, both with the same type of crack, in street cars and they were running fine...Just in for freshening...One was fixed by a guy who was the best iron welder I had ever seen...Once repaired it was absolutely invisible....Both are still running good, to my knowledge... Point is there are people that can fix that properly...I wouldn't use it for anything serious, but then no one checks VIN's and most people dont give a crap about "correct" appearance on race cars anyway.. Dont junk it...Original blocks will always be in demand..and there will always be someone that will want it..\ MB

Seems it isn't that uncommon to find blocks cracked in the mains by the oil holes, (it always seems to be the #2 main for some reason) Does anyone know why that happens ? I have a block being looked at for the same issue so it is something I have been following Not trying to derail scott's post but I figure the guys who know would be following this thread or have already posted here - PM if you prefer

I suspect a load of Nitro methane back in the early 70's was a likely suspect in many cases.

Wouldn't the block need to be align bored, decked, etc. afterwards? What does that cost Bob?
Scott,the line bore/hone and possiable cam tunnel line hone(depending on the extent of the repair will certainly come into play here and depending on the repair process the deck shouldn't be effected.With that said we always recommend line honing and square decking a block as part of any engine build.Block machine work(line hone,square deck,and bore cylinders)usually run about $1000+- As mentioned the fact that you have two oil passages to consider,one straight to the cam and one angled to the lifter galley is the reason you want it done by a professional shop.
