[oldkimmer]

Still for sale. Thanks. Kim

Kim is that a major crack in the block in the last 3 photos or am i thinking of one of my exes?

 

[oldkimmer]

I don’t think so. The machine shop gave it a clean bill of health. I talked to them b4 I bought it. I’ll take it to my machinest and get it checked. Then we will know 4 sure. Kim

[oldkimmer]

I’ll find out in the next couple of weeks. Kim

After the effort in machining so carefully, a cracked block would be a huge buzzkill/ Good luck with this.

 

[oldkimmer]

Paul, I hope so too. Kim

 

[oldkimmer]

Gerald, hopefully all that work wasn’t a wasted effort. Kim

Wow. . . That sure looks like a crack. I don't know what else it could be. Hope I'm wrong.

 

[oldkimmer]

Ripinator, I sure were all wrong. Kim

 

[Big_John]

That's not a crack.

That is a parting line from the sand casting cores meet. All of the 440 blocks that you see will have that line at that spot. Some will look better, some worse.

If I were building it, and especially since I would have had the die grinder in my hand doing the clearances anyway, I probably would have cleaned them up a little, but some builders don't see the need to.

If there was a crack that long in the spot it's in, the block would have self destructed a long time ago.

 

[oldkimmer]

Thanks Big_John. The machine shop checked it for cracks. Then sonic checked the bores. He said he would of never went any farther if it hadn’t passed those 2 checks. It is bored to 3.80 which is a .060 over bore. Kim

If the block was sonic checked posting those numbers could help someone make a decision to buy

It's not related to the sale or a criticism thereof, but FWIW:
Grinding down these 2 bosses prevents this block from installing in a 65 C-body or a late-60s A-body, or using the late 70s PS pump mounting. Would've been better to leave them.

Maybe it's just hte picture/lighting, but this machined dish looks like it has some edges that might lead to detonation hotspots.

 

[oldkimmer]

Every number was ground off the block b4 I got it. This is the story I got about the block. It is out of a 69 M code A body car that was totalled and being scrapped many years ago. B4 it got scrapped someone stole the vin and fender tag. He didn’t want it to get into a car that may be re created and passed off as original. I don’t know how true that is or have any way to prove it or disprove it. The old guy was gonna ceramic coat the piston tops b4 he passed away. Kim

 

[fury fan]

I've never seen a block get those 2 bosses ground like that, and leaving the threads visible was kinda odd if it was for appearances.
That story does make sense, then.
