I know he runs it on the 830, not sure about the 760, though.

 

Hey im looking to shot a stroker 370 r motor. My question is will the o-ring in the head hold all that pressure in? It a pro-x cylinder. What is this NX, is it a company, is it a a product name?? All i know is that gathering all the info that you guys just said i would go with this NX system. It seems everyones talking about shootin your 4 strokes though. Id feel more confident shootin a 4 stroke over a 2 stroke. Anyhow if anyone could chuck me some pointers i would appreciate it.

 

actually a 2 stroker makes more effective and safer hp with nitrous then a 4 stroke.
the NX system you want can be found here
