After digging awhile, I found that speed pro makes a 18cc D cup piston for a 350 chevy, only the rings are 1/16, are these okay for everyday street use? is the life span shorter? KB makes a piston similiar to this only I don`t like KB pistons, I would perfer to use standard rings, but I can`t find anyone that makes a D dish piston for everyday street use with standard rings. Any info on narrow rings is appreciated.

I have a bunch of street engines with the 1/16,1/16,1/8 ring package and i have never had any issues with them.

Are the oil rings on that piston 1/8" or 3/16" either one is ok IMO i was just wondering...

It's better to have a gun and not need it, then need a gun and not have it.

Narrow rings will probably hold-up ok. Most piston manufacturers are actually going to narrower rings. Another option for your pistons are TRW L2441F. These are forged pistons, D-cup style. Contact me if you would like a price quote.

The 1/16" rings will be fine. I would be sure to use standard tension oil rings, rather than the low-tension ones.

Speed Pro #H859CP is a 12cc Hyper dish piston w/ 5/64" rings. Using it on my 383.

Sorry, that # is for a stroker. For stock stroke, check #H423NCP for a 10cc dish, or H620CP for a 21cc dish. Both use 5/64" rings.
