I have an Edelbrock Performer upper and lower intake on my car. I didn't install it . It was on the car when I bought it. It seems like a pretty easy install. Check out their website for instructions or e-mail them with any questions. They are very good at getting back to you and answering any questions. Make sure you use the reccomended throttle body with the intake. 70mm. Edelbrock states up to 37 horsepower gains at 5500 rpm. I use my car mainly for drag racing. I run 14.3 e.t in the 1/4 mile in hot humid weather. I'm sure it will do even better in cooler horsepower making weather.

Good Luck
