Nitrous!...on a cast piston 360

Hey all,

I have a '74 360 in my Demon. COMP XE cam, Torker II, ported iron heads, and a QF 750 on top. I've been looking at purchasing the NX mainline nitrous kit, but the only issue is she retains all of her original cast rotating assembly. The motor circulated some coolant at one point and nearly went kaplooie (some connecting rods are blue but they're still good). It has a fresh re-ring and is still running on break in oil. It may be some time before I pull trig on the kit but I'm curious as to your thoughts on how much this motor can handle. Thanks in advance.
