I am just trying to get the most use from my engine and things are changing all the time.I have 9.5 pistons with .300 1st rind 1/16 with Victor heads and I would like to use the blower at low boost 8# with Sunoco 110.What would be a good ring choice getting away from hellfire?

Just wondering why you dont like hellfire rings? Cost? The toll they take on the bores?

At one time I did have a set of hellfire rings not seal but the second set did so I think it was an error on my part by too much idle time before getting a load on them.

Total Seal has a decent ring for boost, I need to look at the box here in a bit but the price is near equal to hellfire rings if I recall both around $300.

Yes the toll on the bore.summit has hellfire for 166$ I think a n/a ring for 13/14cr is what I am looking for.I want to use low boost and not go for max speed so much as go rounds and use a n/a intake maybe and no boost.

would a Total seal M9190-105 be ok for a 4.351 bore?

I went to there catalog and that part # is not even close.Looking at M6490 and T6490
ps this is the same ductile,cast iron as hellfire,can you give me other ideas pls!

There classic race series rings are not priced bad and might work for your needs.


I tend to use alot better rings then I need and just used the Total Seal CS AP Advanced Profile rings thats a steel top ring with 12.0 comp and a 250 shot of spray in my street racer vs the hellfire rings.

ok thanks! I looked again and a CS6490 has the steel top,conv 2nd std oil but I will call for info.

I havwe looked up some other brands like Mahl,Wiseco,Ross,Perfect circle most with ductile iron,plasma moly coating cast iron 2nd.perfect circle had a napier 2nd.
3150075-035
Mahle 4355MS
Wiseco 4350H Ross RS9798-35
speed pro slp R97985

Don't know if it's helpful, but the 383 in my Fury has been happy enough with 5lbs of turbo boost with what has to be 30yr old ductile rings from a cheap reman house rebuild.

I think I could do better with a steel top ring and lasting longer but I only see total seal with that.The speed pro and Ross rings I listed have just iron top and that won't work.Thanks for your info.

I am in the process of installing a new set of S/S custom top rings for my turbo small block, I discovered moly coming apart on my old set, mild engine, conservative tune, pump gas. I have an odd bore size so they had to be custom from Total Seal.

Total Seal said to use
CS6490-105 conventional set
TS6490-105 sealed top ring
I fogot to ask about with napier 2nd ring ordering
The hone for this was 220,280, plato
