Hey, i've been looking around and i'm a big guy and need more power, i've heard such good things about the 350r kits, and have seen a few run. My only deliemma is i see some companies using space plates with the 350r, (less reliablity) which i don't want to have a stroked motor. Right now i'm looking at ESR and CT racing, i am not exactly sure but i believe the esr 370 is just a stroked 350?? so if i was to get a 350r powervalve from them it would be what i was looking for.. but i can't clarify this as i haven't seen one, Thanks a lot.

 

A lot of the aftermarket systems which are based on the Pro-X cylinder use a spacer plate. That doesnt mean it's less reliable. The plate is used mainly when the long rod later crank style is used. Someone will correct me if I'm wrong, but off the top of my head I am thinking 350 is as big as it gets without stroking. I have the ESR 330 bolt on kit on my wife's wheeler and it really outperforms the 310 kit by quite a bit. Bubba
