I'm using the Edelbrock Performer RPM Cam kit in my 350. Will I need a higher stall converter with this cam? 700 R4.....

 

What is your rear gear ratio?

 

Ashamed to say I don't know right off the top of my head, and the car is at home (I'm not). It's original though, if that helps. '83 Z28 Crossfire........

 

Yes.

Those cars, being a non-performance setup without any kind of high-RPM potential at all, came with a 3.23 IIRC.

You can get far better cams than that antiquated one, for the same or lower prices. It gives you all the familiar "big cam" problems, but doesn't give you near as much of the "big cam" benefits a good cam would.

 

Problems...such as?

 

Poor gas mileage, poor low-end torque and throttle response, low idle vacuum resulting in unstable idle, poor cold weather behavior due to the idle issues, no leave but eventually it "turns on", etc. ....

The all-too-familiar "too much cam syndrome".

That cam has the ancient-style lazy ramps that go with valve springs from days gone by, when they had to design them that way because the only springs people could get were so lame. There are many far better cam profiles around now than those old tired designs. Typically you can get a cam that has the same .050" duration as that one, to put the engines's power band at the same point; but far more lift, so you get more power within that RPM band; and far lower "advertised" (seat) duration, for reduced "too much cam syndrome".

"There's no such thing as too much cam, only not enough motor".

 

First off we need to know what kind of setup (heads/intake/cam) you want to use, what powerband you want your engine to have, and whether or not this thing is a daily driver. Then we can give you a stall speed. You will be very happy if you get a good stall converter to match your engine, so yes you will want a different one. Also, look into Comp's cams. They have, in my opinion, the best cams on the market. By best I mean they are very true to the numbers that they post with their cams. So let us know your setup and we'll come up with somethin for ya.
