Well, look what we have here!

Of course it's the rings...even the guy who put them in my 340 said he has used lots of sets of them ...but always in 1/4 mile race engines where they might see 20 miles in a season. Mine was the first set that he put in a street car, and he won't be using them again in anything that will see street use...he spent Drag Week with me pouring oil into the engine so he learned his lesson!

I use them in my street car. Sold many, many engines for the street with them. The first engine I used and TESTED them on was a 400 Chevy that had a huge amount of blow by. We MEASURED the blow by on the dyno. Then just installed the gapless top rings. Reduced the MEASURED blow by by a ton.

That engine is still running today, stil NOT using oil. Your boy can't hone a cylinder. Face it.
