If I may make a suggestion. When I built my v-8 engine I designed it with 1 iron piston ring. My bore is 1.00 and the ring end gap was .005. I found that I couldn't keep the engine from smoking, oil past the ring. Even after a period of running it would still smoke so I ended up making new pistons with 3 rings, 2 compression and 1 oil control. Since that time It has never puffed a bit of oil smoke. Before you get too far you might think about this.

i Will consider it :) How you done your oil ring ? i have planned to put 2 ring of 0.03 wide in 1 slot of 0.066 wide ! how do you think of That ??

Thanks for your help ! :)

I honestly can't answer your question as I've never put 2 rings in 1 slot. First of all I make my rings by the Trimble method which has been spelled out on quite a few threads so I won't get into that part of it. To make the oil rings I turn the rings to the correct diameter inside and out. I then cut a small groove in the middle of the ring. The dimensions would depend on the size of your ring. I then cut the ring from the stock, clean it up and stack a number of them on a mandrel in my dividing head. For a 1.00 diameter ring I drill about 8 holes in the center of the groove. The rings are then snapped open and heat treated. The oil groove in the piston is cut to depth with a smaller slot in the middle, about .01 deeper. The pistons are then drilled with an equal amount of holes. The small slot in the center allows the oil to flow from the ring, through the piston and back to the sump. I do have other engines that don't have an elaborate ring like the 302 and they seem to work fine but they still have 3 rings for a 1.00 diameter bore.
