If you have mass air there will be a mass air sensor right after the air filter. What year is yours?

Stock vs stock the SD cars are a bit quicker. You can do heads, intake, all the other stuff. Hell i know a few SC & turbo Speed density 5.0s. It can be done. it starts to get tricky when you start playing with the vacume. ie cam swap. There are some nice SD cams out there though.

Speed Density - what you have instead of Mass Air.

speed density is arguably the way to go. dollar for dollar spent on mods they are quicker, however there is a limit to them. i haven't come across it and i can run 12s naturally aspitated...with the spray i'm hoping to get close to the 11s

With a speed/density system, the ECM (computer) calculates how much fuel and timing advance is needed based on the speed and density of the incoming air.

With a mass air system the ECM (computer) calculates how much fuel and timing advance is needed based on the mass (weight) of the incoming air.

just my 2 cents....
