Rusty crankshaft, and cylinder head

[chryslercruiser]

Just dissembled a junk engine. Two pistons are stuck in the bores, and the head is crusty.

The crankshaft has one major rust spot on the oiling hole of one of the main bearings. Guessing that it is pitted at that spot, does that suggest the crankshaft is junk? or can major rust be removed by turning it down?

Thinking this engine is going to donate the camshaft, Oil pump, Rockers and shaft and intake/exhaust manifold..maybe the crankshaft.. the rest is probably too much work to justify.. tho it could be fun to experiment and learn about head porting with out worry of making major mistakes on something that is rebuildable.

Suggestions welcome on what else to look at, or keep. It was an early 60's block, with canister oil filter,

Without photos, it's hard to tell.

The only spo I see on the crankshaft.

One of the lifters is about the same, any chance of it being able to be surface ground and reused?

clean it up with fine grinding paste and a lace or a strip of 1200 or 1400 wet n dry dipped in diesel

it'll be fine

dents don't matter its raised bits that gouge out the bearings

if its is confined to the area around the hole...no problem its a big fat journal
race bearing would be full groove i.e you can have a section of that journal unsupported.... so a bit that isn't supported no problem it will be full of oil


if pitting covers the whole width of the main journal there is a problem and a regrind of the mains is in order.

Thanks Dave,
That’s the only spot, so I’ll call it good.

Take to a machine shop the last few cranks I have had that just needed a good polish coat very little to get done. They'll be able to tell you better whether still reusable.
It's possible with the canister filter it was a truck engine. I had one out of a 64 like that.
I pulled a few parts off of that one and resold it.

That crank would be forged, would work in any /6 built to 1975 and some into 1976 before the cast crank came out. Cast crank and forged crank aren't interchangeable in a given block.
There would be nothing wrong with using that block as the basis for a build, you can get a newer oil pump that will take a spin on oil filter.
I don't remember I believe you could even use a spin on version on that oil pump, it's been a while since I've worked with one "that" old ...
