Thanks for that. Engine had to be done. Was seized, and found out it rolled #2 rod, #-1 was very close.
He had water in base( with oil on top) and so when he checked before starting it had oil on dipstick, but was over full , it didnt run very long and seized, and that’s how I bought it.

Starting to get stuff rolling in now for engine. New pistons, rings etc. Crank ( ground- .010 mains, .020 rods) block bored, and the bills are laying on bench, cornarary arrest happening now!!! $$ mount up very quick. Stans comments- there is no cheap crawlers, is absolutely true!! And as you commen...

Yes, you guys are right on the end gap measurements etc. I don’t believe end gap is to critical in our situation, as long gap is not to tight to start with. I believe a post from Lavoy say’s piston’s for a 440- gas, when available are in 3 sizes, with .045” OS., being one size, but rings aren’t avai...

Gregjo, thank you for your comment and insite. You are very right about cast ( softer) and chrome ( harder ) and when rings seat, cyl walls are smooth. Oil consumption, and compression loss, is hopefully at a minimum when walls are smooth. When a cyl wall is honed, it could be (easily) .003” to .005...

Like I said, I can usually get a good discussion going on this topic! No, it was not improper or bad installation of rings, or improper honing. After much and exhausting checking and analyzing the problem, what they found was the metal the liners was made of( cast iron of some kind) was work hardene...

Forgot to include , all of us old mechanics have either heard, or have done it ourselves, that those “dam chrome rings” used a new set and engine kept burning oil, until I removed them and installed a set of cast rings, engine burned oil for a few miles, usually around 500 miles , then engine finall...

Yes, I remove top cyl “ridge” of carbon and metal before removing pistons, is easier and doesn’t break anything. I can usually get a good conversation going when I mention about not honing cylinder walls that are good enough to reuse, without rebore ( rebore has automatic hone, as Lavoy pointed out)...

Can’t get over what a beautiful job you are doing - you are not rebuilding it, you are restoring it( to way better than when it was new) even noticed on the pics of the dash board, all nuts are even orientated the same way( a “sharp” portion is pointing up)
Very very nice.

Forgot to make it clear that we don’t hone cyl walls, as long as cyl are good to use. Has anyone tryed this?

Absolutely true. That is why I waited until I had new pistons in my hand, but if you take factory specs for reboring on a pre 1955 auto engine, and bore to that( ie- .001” per in of bore- clearance , sometimes find that is too tight. ) I just thought maybe someone on here has found over time that a ...

Tks

Have a set of new .040 OS pistons. ( finally found some at a reasonable price) can we use service manual clearance spec as gospel, or has someone found a different spec that is better, when we rebore.

Darryl, as a suggestion , after engine is warm, idling, trans shift lever locked in neutral, crack each injector fuel line, one at a time, and see/ hear if engine sounds the same, as each one is opened. If engine sounds same( especially #2) , I would lift rocker cover off and do a valve set. You may...

Lavoy, do you have .010” undersize main bearing set for my 440ic 113 cid engine, and if so how much?

Jim B is right on the money with his suggestion , but maybe also check wiring/ key or starter button for sticking and keeping starter engaged.
