INTAKE and CAM combo....

[6FIVE_STANG]

i have a 65 289 and want to get a new intake which will probably be the EDEL. AIRGAP but i dont know what cam to get for it. i want my car to be a daily driver but will LOTS of power. i dont know ANYTHING about cams so you guys have to be very speceific or just post a link of where i can buy it...

Get the Edelbrock cam that is engineered and dyno matched to work with that intake. (but I am not a fan of their carbs) The perf rpm in your case.

They do make a good int/cam combo...

and their carbs are ok, for those who dont know how to tune a Deamon / Holley / BG / anything else..... I guess.

If the car is going to be a daily driver, I'd recommend using a dual-plane manifold (Edelbrock's Performer RPM is a great street intake) and using either a matching Edelbrock cam, or Comp Cams' Extreme Energy cam, #XE268H. My experience with the Comp Cams stick is that it has a good-sounding idle, lots of torque and when used with a dual plane manifold and a 600cfm Holley (model #1850) it easily gets 20mpg. When shopping for a manifold, be aware that lots of modern, open-plenum, air-gap small block intakes have larger ports than the older-style heads. They'll bolt on, but may not work as well as you'd like due to the port mismatch.

Unless you're going to pull the heads and have screw in studs and guide plates put in them, Go with a cam no larger than the Performer cam(.448/.472 lift--204/214 duration) This cam will work even with the RPM intake, don't let anyone tell you different. Go with any bigger cam over .500 lift and 220 duration @ .050 and you'll start popping the studs out of your heads. It'll be a good idea to change your valve springs to new ones that match that cam, although it'll be fine with stock springs, the stockers are likely worn out.

Hearne's right, and that's a good example of having the right combination to get the most out a cam. Stabbing a bigger cam in a motor with sacked valvesprings and press-in studs won't cut it. Trust me, I learned that lesson the hard way...

Agree with Hearne, although I would like to add that their is a different level of flexibility between cams and intakes. I have run the RPM intakes on basically stock motors and they have worked fine. The RPM cam, while maybe matched to the RPM intakes maximum potential, is not a very good daily driver for a 289/302 Ford. It's a bit too aggressive, especially with a stock TC and heads. It's vacuum at idle is only 10-12.

The Performer cam would be a better choice.

Also, many factors come into play when selecting a cam, such as rear gear ratio, torque converter stall, heads, etc. All the good cam mfg's have toll free numbers to help you decide.

Ok, well im going to buy a intake and cam soon but i dont know the diffrence between the EDEL. RPM intake and the EDEL. RPM AIR GAP intake...

Go to Edelbrocks website and look at the pics of the two. You'll see why it's called an air gap intake. If you don't see the difference..............................
