I am no pro, but have 6 lb pull in my SS LT1 right now. Have had as low as 4.5 lbs, but it left a blue cloud on the starting line. Never dyno tested both ways, but ran the same times both ways.

Go with a Napier second ring and a 7 to 9 pound oil rings.

Thanks Ed. Really don't want a lot of smoke. Was thinking about a 11-12 pound package. What's your opinion? What is to much that it will really put to much drag? Thanks for your help.

I use a Napier with 6 lbs. Dry as a bone.

What is the correct procedure to check drag from the ring package? Cylinder vertical or horizontal, dry cylinder wall or lubrication on the wall, if lubricated with what and how much, just piston with pin and oil ring or is the rod on it too. Is it the breakaway number or the dynamic pull reading?

This is what I run. I am not the fastest but run well. I ran some 9 lb rings and they were OK too.
