Summitracing sells these as well as a few other places and i was thinking of using them but wonder about them holding up to a 150 shot. I am building a 355 Lt1 (.030 over) and bought SRP forged pistons but cant decide which rings to get. What is everyone else using, I wont be using nitrous all the time just at the track hopefully. I emailed Total Seal and the tech said they would work as long as they are gapped for using nitrous. I guess i dont know what he's talking about. I just want ot get a good set of rings so im not tearing this thing down in a year to put rings in it. Thanks

 

Ok well if you dont know about total seal rings then can you post what rings you are currently using and weather you like them or not. Thanks

 

I have run regular Speed Pro Moly rings in my past motors, with the gap opened up for spray. Unfortunately, you get a little more blow-by due to the larger gap. I plan to use the gapless rings on the next motor, but either way, you will have to open up the gap for spray. Usually only the top ring needs to be gapped larger, especially on a total seal type set.
