Great suggestions please keep them coming.... I told machinist no rush so I do not know if it will even get to the hot tank for a week or two.
Thanks Al, sounds good.
Don, do you mean visible or spec wear?
Everett, New lifters and push rods with the cam? Timing chain? double roller?
How about an oil pump suggestion?.....again, not worried about my stock one just want to make sure I have good oil pressure.
Sorry, for all the q's but I have been neglecting my homework and have been away from my cars for to long....fwiw, I am searching the past posts for info...and will retain all original parts for the next care taker......so no worries there.
Matt, what I was referring to is that normally when someone buys rings for a specific bore, the stock style ring gap is built in but adding any additional bore wear just makes those stock ring end gaps larger .
If my piston clearance is acceptable, I normally get the .005 over size ring. A normal set of .030 over bore will take these type rings but if you want to get picky and control ring end gap that controls more blow by , you can specify .035 or even in stock applications .005.
I recall Ramco rings offered this and I think Sealed Power or Speed-pro does.
Its not a mandatory thing , just old tailored engine specs.
To take the full benefit here, ring end gaps need to be filed to fit into the engine bore without the piston about an inch into a square bore then measured with a feeler guage.
If you don't fully understand it , no need to mess with it.
Stock Z 28 oil pumps or Mellings pumps are good. Just make sure the oil pump pick up tube is tack welded on or bolted on.
