I am going to have a cam put into my car in about 3-4weeks. I talked to Comp Cam. And here is what cam they told me to get. It is a roller cam cam#31-760-8 Grind#288R <U>[email protected]</U> intake 586/586 ex. rpm range 2200-6500. My motor is a 67 289hi-po with stock 480cfm holley 4bbl, stock Holley commander intake, Jba Headers, T5, DUI Distribler and 3.80 gears. The Comp Cam guy it will be very streetable. I figure a Edelbrock rpm manifold would work great and edelbrock like 750 carb, and AFR heads or Edelbrock Victor Jr. Heads will work to 500+hp in the future. Right now i have like 360hp. I am thinking a 50hp gain from a 40year old 447lift cam to this nice roller cam.
