Upgrade: heads vs. nitrous?

As much as possible without major modifications or breaking anything.
I don't think the cam set up is really helping me much either. It is great when I'm sitting at a light, and the car is rocking back and forth, but I think that is all it's good for. It is a 292-292 duration with 512 max. lift.

to get the best results out of the combo its best to go with a custom ground cam.
its hard to recommend things without knowing exactly what u have now, what are the specs of the motor?
The guy I bought the car from TOLD me some things about it, but didn't have paperwork for anything. I was doubtful, but I did see that the crank had been knifed, so I am pretty sure the rest of the info he told me was true...
It is a 351W, 1972 model (got the engine code)
He said it had 10.5:1 compression
GT40 heads (ported polished, and flow tested)
comp cams upper intake w/ 1 inch spacer.
24 lb injectors.
He did say the cam was a custom cam
Other than that, don't know much else. He did tell me he had it set up to run 150 shot, but he never got around to it. I'm still a little worried about blowing something, but it seemed like he did everything the right way (older guy with money, all work was professionally done)

The decision here is an easy one. You can make it on your own by answering these following questions...
Heads or nitrous...
1) Which mod will lead into making better power WHEN you do build the engine and supercharge it?
2) Which mod would you not be selling when you supercharge?
The nitrous is nice and all but only a means to a temporary fix. You will lose money when you resell the system. Unless you plan to run the supercharger AND nitrous once your built then don't bother. The heads would already be a logical step in the power making process for not only N/A but also blown as well. They will cost more than nitrous but it will be one less thing you will end up buying later on, and you won't lose any money on them because you wouldn't be selling them after the real build. The nitrous might be a little more run right now but doing the heads is the smarter move.

I definitely agree with you, but I don't think a set of heads that is good for my current set up will suffice for what I plan to do in the future. Plus, I am thinking it would be wise to go with a stronger block for the build I want to do. I'm afraid that 700HP will crack the current block I have. I have fallen in love with the new Man' o War all aluminum blocks. The 351 versions can be stroked out to 460ci. With that many cubes, I probably won't need a supercharger, just some nitrous, and I will be ver happy.
Whatever plan you end up going for stick with it and don't deviate. Sometimes you can have your cake and eat it too. Other times you cannot. Once you start changing your mind here and there you will find it take one hell of allot more time and money to reach your initial goal.
