scott J,

First of all you didnt win, you have no idea what your talking about saying the button being in the ring land doesnt matter. It causes oil consumption.

Second the top ring needs to be .4 down from the top in race motor or if your using a power adder. with a 1.23 ch piston minus 1/2 you button size .458 leaves .762 for all three rings. then lets but the top ring .4 down from the top for safety, that leaves about .304" inches for the second ring and oil ring, assuming your top ring is only .001 thick, which it is not its 1/16..
So I would suggest you redo your math..

The only way this works is by using a super think oil ring, and running the top ring so close to the top of the pistons you run into others problems. Now why of gods earth would you do this scott?? The answer is for the guy who wants to impress his buddies he has a 433 or 427. At least this excuse has a reason for using this type of a piston. but I cant think of one reason to do it on a 351 with no stroke. Unless you like having oil consumption, or pinched top rings, or many other problems with haveing all the rings with in .762

scott sometimes it better to let people think your a fool then open your mouth and prove it.
