Okay guys, I bought the engine I posted about a couple weeks ago. 440, removed from a crashed mud bogger, edelbrock performer intake, deep sump pan. The guy dropped the price to $380 with the trans. Sold. Fast forward. I got the engine home, pulled the trans, pulled the plugs and valve covers. Everything looks clean with a light surface rust on a couple of the rocker towers at the front of the left head. Spark plugs had rust around them but I think the thing was stored a year and still has mud on it from its bogging days. Those two plugs with the rusty threads near the electrode were on the front left. I thought maybe moisture could have crept in from the exhaust port if the valve were open? There is no sign of breakage. One push rood was loose enough that I bumped it and it popped from under the arm. I can't spin the crank. It goes 1/3rd turn and goes clunk. So I pulled the pan. No shavings or ground metal. Oil is nice and smooth. All the rods, pins, pistons, cylinder walls, bolts, crank look fine. As I tried to turn the crank again I heard what sounded like a clash up on the left front... like the piston clunking into a valve. What's next? I guess I strip her down, check the cam lobes and lifters. Everything looks so nice and moves pretty freely until it stops. The oil pick up has no metal in the screen and looks brand new.

Could be a bent valve OR a converter bolt backed out and is hitting the block.... open it up EDIT I see you pulled the trans... cancel that idea of the conv bolt

The rust on the 2 plugs in the foreground on the right is telling.
Exactly. Probably a frozen guide in the head. Might not be any damage at all per se, just a stuck valve from it sitting with water in it.

I'm thinking you just have rust in a few of the cyl that the rings are hitting... maybe a bent or hung valve

I'm betting on rust in the cylinders first and then a stuck valve in a guide Please let us know what you find

Ding! Ding! Ding! Winner, winner, chicken dinner!!!
Well, here's what I found.
7 of the bores look like this.
Give or take carbon, but they all look nice. That is except for #8 which looks like this. #6 is okay but you can see where some moisture was in the head affecting that plug, and #8's valves were rusted up nicely...
All the lifters looked pretty with the exception of a couple that looked like they may not be rotating in the bore real good. smooth but black stains. the two on the back end were gummy as you can see and the cam looked gummy too. The lifters came out with a little coaxing gooey orange in the top from rust but still functioned. The cam looked pretty except for the back end which looked like this.
Sad that that bore got wet. It's nasty. Feels like 40 grit. So what's worth keeping, what do I throw out and can the block be cleaned up and honed or does that rust mean it's going to need a larger bore? is the cam dead or can the lobes be cleaned up? I haven't got to the front of the block yet so I don't know what grind it is. Too bad. Then engine looks like it had very few hours on it.
Sorry for my naivete. Just trying to learn. And also trying to get an engine in the car on a low budget. with plans for a 451 in the works.
I’m listening.

Its gonna need a bore job.... now its a matter of HOW MUCH.... I'd forget the cam also(but thats me... I dont play with hyd cams in so called race engines).... start pouring oil and rust breaker in the bores so you can get it apart
