Per the box these rings are 1.75, 1.75 and 3.5

Just wanted to check with you

Side clearance on top ring is .004
2nd ring is .003

Stock is .002 to .003

Backspace is .026 vs stock at .016

Any concern with backspace or top ring?

LGAFF · 08-01-2011

Called total seal; .040 is when you start to have back clearance issues.

Lee,use the Total Seal rings and if they work we have another source for stock replacement rings,if not no biggie yank the motor and change to stock OE rings and done,it's some good R&D.

What's the part # on these Total Seal rings.

Mine show as Custom order.....they advised these are the widest rings out there on the market right now......nothing closer. Easiest way to access is to have them check under my name. Calling Wiseco and a few piston companies to see what pistons would cost that use a more common size..like LS1/LS6 3.898

Lee,

You should be good to go and I know when I was contemplating the issue I had consulted with several builders. I had a little more clearance than what you are showing so I had concern with those rings and used OEM instead since I was able to get the last of loose sets from Jerry. Two of the builders knew of the ring issues from Total Seal and one used them. He said he could not notice any issues if there were. Even though I did not take a chance on them, I bought a back up set since I got it for a little over $120 as those rings I felt were better than no rings.

I spoke to 2 other companies, they stated that they will not be an issue...

Wow this is a PITA

LGAFF · 08-01-2011

Soooo, one builder thinks that the extra clearance is from wear (on the piston)?

Also, one builder thinks that it's okay but he is speaking in terms of a "hard wall" and a "hard piston" ( aka forged piston?, but ours are cast ) vs a cast iron bore and a cast piston.

btw, thanks for the link Lee.
