If properly set up and cared for, moly rings should last 100k+ miles.  How 
much do you plan to drive the car?

Remember that even the lowest price standard cast pistons from Clark's (or 
any other vender) will have way better metallurgy, casting technology, and 
finish machining than the original GM pistons or anything else commonly 
available back in the 1960's. Based on your description of intended use, I 
would think that the standard cast would be perfectly adequate.

As a matter of comparison, I am having Ken Hand install Clark's High Tech 
pistons in the rebuild of the 110 engine for our '65 Greenbrier.  The 
factors for considering this upgrade from the standard cast are; 1) its an 
FC engine--higher load & hotter running, 2) I plan to put 5000+ miles/year 
on the car, hopefully for 20+ more years, 3) I plan to do a fair amount of 
autocross/rally competition with this vehicle.
