How can I improve this Cobra?

I would be in this camp. Sounds terrific.

As you probably know, always consider the rear gear ratio, intake, cam and carb together, when exploring the HP possibilities.

Do you know the specs of the current cam?

Also, getting a nice set of magnesium Halibrand wheels will lighten the car up a bit.

Head work/intake work, camshaft.

You don't have to ditch the heads, but a well thought out port job would let the engine limber up a little bit.

A more aggressive cam does several things:

1. Moves the curves to the "right". This means that it takes away from the low end power, and depending on the head flow, can take away from the high end power as well...depending on how much more aggressive you go on the cam.

2. Makes the engine a little more "fussy" on idle and low end. This could result in making the engine harder to tune, making the engine "buck" when cruising in overdrive, etc.

If it were mine.....I would lean towards:

1. A deeper rearend gear. Since you have the OD, a 3.70-3.90 rearend gear would wake the car up quite a bit.

2. Head work/intake work.

3. If you wanted to get real deep in the engine, a stroker kit...

Keep in mind that with increased head flow, comes the ability for the cam to work a little easier. So look for a step up in where the peak horsepower rpm is.

change to Webers. The cam is probably about right for them and you will never regret to look and performance upgrades
