    well im getting ready to put together the stroker motror for my street car and was wondering if O.E. piston rings made by speed pro are going to hold up ok or should i use something different? the guy that did the machine work and chose the rings is a very reputable engine builder and he is pretty conservative so i dont think he would give me something he wouldnt use but what do you all think the motor is a

    Speed pro rings are good so are Hastings and Perfect circle. I use Perfect circle rings at work and never had any issues, ever.

    agree, speed pro are good rings, IIRC, they are made by federal mogul and are what GM uses.
    i almost always use hastings rings, unless i go with a moly ring. they are made not too far away from me and are what just about everyone carries around here.

    Get a set of rings from him....Also, ask him for the directions from the KB pistons about the ring fit. KB pistons require a different ring gap than normal, and must be file fit....
