Cam/Intake or NOS? What to do?

[Skyman]

Well I just got a tax return from the good old state of california. I wasn't expecting that. Anyways, I have exactly $500 to spend now.

I was thinking either a dry 100-125 shot of NOS or a new cam and new intake.

I was thinkin an RPM intake a .530 lift or so cam. I will probably lose some gasmileage though with this and I dont know how much more gain I will get. I was thinkin of shaving the heads at the same time for some more compression.

THe question w/ the nos is I want to do it all right. remote opener, timing adjuster and everythign so I can run it all from the drivers seat. What do you guys think I should do? But the nos wil retain all my drivability I currently have when off it, I just dont know how my clutch and rearend will hold.

My dream has always been 110mph on motor with 20+ mpg.
