more slant6 hp!
Is nitrous an easy install? what other upgrades do you need to do first?
Nitrous can be an easy install, or it can get involved, just like any other mod. I have a "fogger" system on my Cuda with a 170. It has the capability of over 300 hp. I have run up to 175 hp, and have broken parts. Cost of the system, including fuel pumps, lines, gauges, etc, was about $1,000
My 66 Valiant with a 225 has a plate system on it. Just mounts between the carb and the manifold. It is a 100 hp system. Cost of system, at a swap meet, $125
It is even possible to put a couple of "fogger" nozzels, in a stock manifold plennem, for a low budget, low power system.
If you stay under 100 hp shot, you will not need to do any mods to a good sound engine. Biggest thing, make sure you have a fuel system in good condition (if you run lean, goodby engine), and don't run too much ign advance, or too hot a spark plug.
Just remember, with nitrous, you have to pay to fill the bottle. Also, I don't know if this is true, but I have heard, that some states/towns, have laws against nitrous on street driven cars.
