And found the head bolts hooped with.....
Hummmmmm, could it be.... nawwwww, no way!!!

So now I’m like, WOW! That’s weird! This cake out of a ‘78 P code Cordoba.... OK, which means nothing....
So I take the bath tub kit and... dang that’s clean!
Hummmmmm m

Cam close up...
Valve spring close up...
So is that anti seize on the head bolts or RTV? Either is acceptable to me. It does look really clean on the inside.
Tiny little things. lol
Pistons up close... stockers and probably replacements.
Anti seize, good fresh color.
Yeah, perfectly acceptable in my book. I hate it when a head bolt breaks off. lol
Hay, are you finally done playin with railcars now?
4.332
Looks decent! What are your plans for this one?
Less than 10 months. I hope! Everybody tells me, you can see the light at the end of the tunnel! I say yes I can, it makes me nervous though! They ask why? I say, how do I know it’s not a diesel coming down the tunnel?!
It sure yet. I’m about to rotate the assembly to see where the slugs sit. I’d like to do a TF headed 470 mechanical 6 pack....
Shouldn't that be 4.342? Maybe carbon buildup?
That’s what I thought...problem with Pittsburgh calipers? Moving to fast maybe? Front to back measured 4.333
Slugs sit low... below the chamfer @ .1220
They vary. Strange. Mine was .115 in the hole.
The difference could be this is rebuilt?
(EDIT... Not at TDC by 2*’s.)
It’s very clean in here. First big block I opened up. Are they normally like this clean? The 452 heads are clean as well. 2/08/1.74 valves. IIRC, that’s the size.

I've only seen 1 of my big blocks being dirty in the valley. It was a high mile 440 r/v engine with a rusted out valley pan from a junk yard. Usually if they're just cracked open there's metallic paste stuff sitting near the lifters, so my guess is its most likely been refreshed. Pistons look like factory, & that's the ridge causing the measurements definitely

That's what I'm doing except I'm not going to use a 6 pack
Good luck with your build
Thanks! What’s your CID on that build?
Also, who’s slugs?
I’ll tell you that I didn’t expect such a clean valley when I opened it up. The rotating assembly spins easy by hand. Lifters pop out no problem.
I didn’t get much done today on it. Busted out some wrenches to un do the engine mounts and transmission cross member, took out a fan relay... LOL!
Not much done at all.
Once I degrease the heads some, I’d like to sell the 452’s. I don’t know there worth. Can’t ship them so quickly. No suitable boxes around. Heavy iron and such.... This mill needs to be lightened up!
pishta
I know I'm right....
451 rotating assembly is same price as stock stuff nowadays. Drop in 383/400 sized 440 stroke crank from 440 source or Eagle, 400 rods and off shelf KB 383 rod stroker pistons. 400s were low comp smog motors , even in HP dress. Had to up the CID as the smogged 383 motors were putting down 360 numbers trying to cut NOx emissions. Make em cooler and bigger.
Certainly if they are well maintained. My 331 hemi was horrible on the outside but was the cleanest used engine inside I have ever seen.
Oh yea, been to 440source before. Being the comp ratio of the 400 is horribly low, with not much to do with ease to raise the compression up in a meaningful amount, shy of new slugs, there isn’t much to help it.
Swapping to a smaller chamber cylinder head without milling the head can net an approximate 8.5-1. While that is fine for some reasonable street power, I’m not so sure it will like a sizeable cam around 230@050 & up. I’d settle for a 224/226 @050 intake duration and some really good cylinder heads. Though I’d be leaving more than some of the heads power on the table without a good lift to couple with the cam, it would still make a really good easy going driver with good top end.
In my head, I’m working around a 6500 rpm limit.

I have a few good pieces, a few not so good.
