Quick 'n dirty 240 rebuild?

[Oregoon]

Advise me, gents...

My original '66 240 went south recently, due to a rod knock. I came up with a very clean (externally) used engine--another 240--from a '71. However, when I pulled the pan, I found that it's pretty grimey in there. Engine hasn't had a lot of oil changes. I pulled the main caps today, and two bearings are showing a bit of brass. Rest looked fine... Thrust is .007 (well within spec), and the rod bearings look good, too. I've never heard it run, and I have no way to compression test it until it's in the truck.

I'm tempted to throw crank bearings in there, seal it up, and run it. Maybe do rod bearings, too? What about cam considerations?

Maybe I ought to just bite the bullet and buy a rebuilt?

Any better ideas? Any other good ways to tell how much life is in there? This is as deep as I've ever gone with an engine, and while I'm having fun, I'm still learning.

if the bearings don't look really worn I would put it together, run some good heavier oil and put some miles in it. If you don't drive the hell out of it a 6 cyl will last forever. Make sure there is no scoring on the crank. can you post some pics of the bearings?

I can, and will over the weekend.

Thanks!

Slap some Main/rod bearings in it (cam bearings wouldn't hurt) and some iron piston rings and gasket set and away you go.
