Crankshaft carnage

[Rusty 72]

So my 318ci had a knocking. Surprisingly it didn’t sound horrid, but sadly was damaging. This is the picture of what a spun rod bearing looks like. I can’t help wonder if the broken bits of valve stem seals that had almost completely covered the oil pickup had a hand in this. When started it always had 30-40psi of oil pressure but then would dwindle to about 5-10psi at idle when hot.
Soooo I pulled it and have a used 360magnum I’m gonna put in its place. I guess my question is what to do with the 318? Not that I’m a hoarder but I hate to just throw it away? I know it’s not desirable but maybe could be used for a stroker in the future in another project? Or am I just being sentimental?
Thoughts?
Thanks Jeanette

That really looks like the rod was bent as well. Have it measured by a machinist to help make your choice. Normally you need meat on the load side for a stroker, and yours is wiped off, so it may well be junk. HTH, Lefty71

If you have the room keep the block and toss the rest

IMO, the cost to salvage/machine will far exceed the value of the motor.

I can have the journal welded and grind the crank. Crank grind $110, journal weld $50.

Make sure you use the 360 torque converter also as the 360 is externally balanced.

 

[Rusty 72]

The cost exceeding the value was exactly what I was thinking too. Good to know 69Bee that it is possible to save it. I'll stuff it in a corner until I decide what to do.

Yes I do know they're balanced differently. I'm using the magnum flexplate so I think that clears the way for me to use the 318 torque converter.

IMO there is nothing left worth saving. Kinda like a /6, cool but...
340-360-383-400-426-440 different story.

I'd hang onto it. 318's are underrated. Plus, you never know if it'll come in handy in the future.
Over the years I've gotten rid of a lot of parts I wish I had now.

Yep everybodys just dying to put a 318 in their Road Runner. Don’t get me wrong it’s a good little engine but there’s literally millions setting around.

Ceedawg, I hear you. My point was, you never know.
And, I really am thrilled with the 318 in my '69 Coronet. My first 318 and I was pleasantly surprised.
