I had an 87 LX 5.0. Bought used in '89 w/ 40k mi. Ran 150 shot dry NOS kit until I traded it in with 75k mi in 1994. Ran 12.40's @ 113 consistently - almost every weekend - with just a couple bolt-on's, 3:27 gears, and a completely stock engine. Never had a problem with it as far as the motor goes - blew 3rd gear once when I got off the throttle at high rpm - obviously shoulda went to 4th to coast... but my point is, with the right tune = enough fuel, not too much timing, the 5.0 engine can handle the 150. If you're a 4.6 version, I think the biggest worry is a back-fire through the plastic intake. 5.0 had aluminum. the plastic might break apart with a back-fire. As for the piston horror storie, they're from poor tuning. If you hear "knocking & pinging" (pre-ignition / detonation) you need more fuel and/or less timing. Otherwise, it's perfectly safe. As for wet vs. dry: With a dry kit, you're only adding nitrous into the intake - the additional fuel is added via the injectors with higher pressure, and/or booster fuel pump, and or bigger injectors, etc. This is typically easier to manage. Wet systems spray nitrous AND additional fuel into the intake. This is typically for when your fuel system can't add enough fuel to compensate for the additional oxygen your adding via the N20, and I think this is where most of the horror stories come from. I think that part of the problem is that you're spraying a wet fuel through an intake that is designed for air and the fuel sesn't atomize and distribute properly, consistently, and equally.
