I agree, I wouldn't give up on the 292 just yet. Run it for a while and see what happens. After a "re-break" in and another oil change as sweepleader recommended, check the Compression. Maybe even add a can of STP in it. Change the Valve Cover Gasket and check the Side Covers in the meantime. Time will tell if it's worth keeping or not.

As much as I am a Detroit Diesel fan, a 6V-53 is not a good choice for your '64 C-60. A 4-53, especially a 4-53T would be a better choice (It will fit a whole lot better and it's also a whole lot lighter). But then you may also have to change the Rear as you may find that your top speed may be pretty low.

But again, I would give the 292 a good try.

Keep us posted on it.
