I would just leave the second ring off the TRWs. Stick a Herbert cam kit in it and run it.
I agree. Watch the rpm, proper cam and let it rip. To many times we worry about what might happen, not what will happen. There's been thousands of motors built with old cams, old pistons, stock rods. Ideal, no. The best set-up, no. Will it work, more than likely. I've seen plenty of modern piston, modern cam motors that are turds, as well as old school stuff that runs better than it has right to. For what it's worth I've run this style piston with a single compression ring in the past w/o issue.

I tried one time of not using the second ring on NHRA legal Street Hemi motor, never agian on a motor that does not have a vacume pump   It started smoking and using a tiny bit of oil right away   I wouldn't try it agian now either, especially on a street and strip motor

I think the OP has decided on running a different piston........ but if he wants to run the TRW's then have the rings back cut to a .155 radial wall........... it will be huge in gains...

6K I think you're plenty safe, don't know much about the RPM rods. A buddy has a 440 thats been together for years with the heavy six pack slugs AND six pack rods, he used to turn 6600 on the track (Street and Strip car) and hes been beating it on the street for years. Oh and his tach hasn't worked for the past 10. Who knows how high hes been zinging it  All I know its its a 440 A body with slicks and on the street, its shits and gets for sure
