Should I leave my car alone? I read a few things on your site about to much power. I recently got rid of my mustang vert, and got the firebird vert. I thought the Bird had a lot more class than the mustang. I kinda felt like a *******. I "LOVE" the car but it was a tad slower than my stang. So I was going to have some easy mods done to give it that extra kick! Now I'm a little scared too.
Please give me direction! Let me know what mods I dare make.
Remember I am only a JCPenny model, they don't pay as much as you would think. P.S. no emissions in MI. V8 TBI, Thanks Danielle!

 

You could try to mod the aircleaner as a first mod. The stock aircleaner element can only effectively feed a 305 motor to 4500 rpm and that isnt even the greatest restriction, the single neck that is approximately 1" by 2" is, not enough flow for all but the weakest of 4 cylinders. With that said some modifications are still possible.
Remove air silencer ringthat is tack welded around the mouth of the aircleaner that encircles the throttle body. This requires air to enter directly from the top. Removal requires breaking the tack welds.
Removal of Thermac Device: The thermac is a temperature/vacuum controlled valve that directs heat from the exhaust manifold to the intake when it is below a certain temperature to decrease emmisions. The flap is a direct threat to intake airflow. To remove: The vacuum hose that connects to the aircleaner from the throttle body must be plugged. Remove the preheater duct hose that comes from the top of the exhaust manifold. It may be left at that however for added gains one may "Gut" the device by removing the flap, rod and plunger from the intake path. This requires a bit of ingenuity and a bit of a hack job. You will need to cover the hole on the bottom of the neck if you are ducting cooler air to the aircleaner.
Ram Air. The neck to the aircleaner has an opening that is 3" in diameter. Most hardware/home stores sell 3" diameter aluminum ducting typically used to expell hot clothing drier gasses. If your battery is on the passenger side of the car you are in luck. You will need to relocate your evaporative canister located in the front driver side engine compartment. I have moved it over to the framerail next to the radiator though removal of cruise control is neccesary. From there you will need to make a slightly larger than 3" hole in the sheet metal where the EVAP. canister used to sit. Run the aluminum ducting from the neck through the hole and affix it to the bottom of the car facing forward. At speeds this will create a ram air effect pushing cool air into the tubing.
Lid from 350 GM pickup truck Any aircleaner lid from any carbureted or TBI chevy truck from 1968 to current allows for the use of a taller aircleaner element. This will provide gains until the rpm at which the neck becomes the greatest restriction.
You could also get a TBI spacer

Hope this helps a little… hey, post some pics ! …of the car that is

UH, well that sounds great, but I was going to suggest just having SFC's (subframe connectors) installed. Then you could do all the "modding" you wanted. They're not free of course, but any mods that would twist a vert would cost a bit too.
