The Melling CCS-1 camshaft is back in production, in at least a small quantity. A local parts store like Auto Zone or O'Reilly's should be able to order one instead of dealing with the resto-ripoff people. It's a slightly more radical grind than the Corvette/261 cam , which will improve torque without dropping intake vacuum or creating a rough idle. Obviously, a new cam will also require new lifters to go with it. Try my cylinder taper check, using a recycled piston ring, a feeler gauge, and a calculator. It's in a tech tip somewhere. If the taper is less than .005" go ahead with a hone and re-ring job. If you want to send me your pistons and rods, I can put a knurl on the pistons to reestablish the proper skirt clearance, and recondition the big ends of the rods for the proper bearing fit. That's what I did on John's 261 several years ago. No point in doing another rebore, unless the taper wear is excessive.
