    So the mains look ok. What I can see of the lifters and cam lobes looks fine. Cylinder walls no scoring. Damage seems confined largely to 1-2 rod journal and lightly on 3-4,5-6 Clevite has an image section of common bearing failures. Anyone got any thoughts? I have some but I'll wait if there are any replys.

    Dunno. I'm dropping the crank off this week. Im sending the bearings along, want to get his opinion on the damage. That will determine which direction I'll go. I keep staring at the even fire on the floor , but an even fire flywheel is $320 for starters...

    Drove around Blackwater Forest. Got good and muddy. Almost sunk her once in a big puddle.

    I dunno. I am certainly not the one to ask, but it looks like the bearing was too tight on the crank. Not enough clearance. Maybe something behind the bearing shell.

    Machine shop says oil starved, crank is toast won't turn, recommends full tear down for inspection. Punting......what road gears would you guys run with a TH400? :cool: 3:73 cut it with a slushbox and low range off-road?

    I’d run 3.73s. (y)

    You said punted... didn’t know if you meant the crank or the whole engine.

    I have a fresh 231 with a few goodies inside, a Commando 400/20, Centered flanged 44 and an NT 30 with 3.73. I can scab a tranny cooler easily enough. This was earmarked for another project. The even fire will fuel injection easily enough. I can use the squirreled m21 and rebuild the odd fire for that project (grocery getter/ weekend tripper)

    Don't know if you can see but cam bearing is pitted. Cam looks ok, lifters look good. I'm convinced the oil was there but the 30yr old assembly lube dried or deteriorated.

    All the bearing surfaces where it was used are shot.

    That's a bummer on your oddfire. I like my oddfire but in my mind I have been really going back and forth between rebuilding it someday or swapping it for a smooth 350 chevy.

    How much is shipping an even fire flywheel? There is one included with the $150 even fire motor on Craig's near me.

    Can't fathom. $50-100?, A new one is 300+
    $150? Buy it and shove it under the bench.
