ok im gonna build my engine its a 96 block and it getting comp 274H cams stage 3 ported pi heads beehive springs and stainless steel proflow valves as of now but what would be a good combination for pistons and rods and the rings i need the specs of the right sizes to get it will be bored 30 over and i dont know what the piston size or ring size needs to be and i want to keep the stock stroke due to the big cams. more compression wont be a problem. i plan on getting forged pistons too what do u guys suggest? and i might be goin the nitrous setup after that and what all do i need to be able to handle 450-500 hp incase i go with a nitrous set up

realistically how much do you plan on spending?

That it a great kit. Call them instead of orderingit off of ebay and you will get a better deal on the shipping. I bought that from them.

You do not want to go .030 over. You will be changing headgaskets everyweek and wondering why. Its because you will have very bad sealing problems with the .030 over.

Those rings are file to fit. Since you are planning to do nitrous I would suggest the gap on the top ring to be set at .021in and the second ring be .022in.

The way to figure out ring gap is very easy. It bore X .006 for the top ring and .0063 for the bottom ring for nitrous or blown engines. For NA motors it should be Bore X .004 top and bore X .005 for the bottom. For a heavly modified NA engine the top ring should be changed to bore X.0045.

These are just recommendations of how I set ring gaps for engines but there should be a min. ring gap from the ring manufacture so check that.
