Now the meat and potatoes:-)

Dished pistons, but condition is good, small valves, but condition is good:-)

Al bought this as a running engine "with a cam" half the head bolts were stinging tight and half were finger tight, some were painted and some were not so the heads were off before he bought it or during the installation a few high schoolers forgot to use the pattern to torque?

All the rockers, and bolts, and pushrods, looked very good, just some surfaces with a tiny bit of wear in the normal locations such as in the bottom of the rockers. All even and all good.

I spent some time in the garage last night:-)

Removed the:

Water pump
Harmonic damper
Timing cover
Oil pan
And one piston and rod

Found the bottom end to be clean, rotate freely, and has been rebuilt previously. The Pistons are 0.030" over and the timing chain is a dual roller.

I was happy with what I have seen so far, looks like a fine candidate for rebuild and use.

Spent a good deal of time cleaning up oil off the floor, I couldn't drain the pan easily and missed the tray I prepared:-(

I will contact the machinist to see what dimensions I should check before disassembly, I took a middle piston out so I can check piston to deck height at all four corners, I also plan to check end play at the thrust bearing.

Just a suggestion -- if the .030 out bore will not clean up or out of tolerance you may want to go to .040 out. Your machine shop can hone to that instead of boring to say .060. Also, if something were to "happen" you still have room to bore further. TAZ

Re: Ryan Weaver's 1969 Olds Cutlass S W31 Club Coupe

Good suggestion. Oldsmobile stuff isn't as readily available as other brands, so "saving" a good '69 vintage block is a wise thing to do.

Re: Ryan Weaver's 1969 Olds Cutlass S W31 Club Coupe

Thanks for the suggestion.

0.040" would leave one more boring for future. (My the "interweb" I have read many accounts of sonic checking and boring 350 Olds up to 0.125" without issue so 0.060"-0.070" should be no problem next time.
