How much horsepower does a 292 cam add to a 350?

Answer 1

There is no set number as to how much horsepower the addition of a particular camshaft will add.

There are many variables that go into the performance of an engine, from the heads to the ignition to the oiling system. So many, that no number can really be assigned.

If the prior setup of the motor is known, perhaps an estimation can be made, however this would be very rough.

"Chevy 350" is extremely ambiguous, as the cam's performance increase would be based on the compression ratio, the heads and all of their specs, the ignition setup and tuning, the intake manifold and carburetor type and tuning and much much more.

The 292 is pretty lopy camshaft for a high rpm range(up to 7000rpm) and will not be good for a low compression, low output motor.

Here is a snippet of info about Isky's 292 hydraulic flat tappet cam from their website:

"292 Mega Hyd.

Compression Ratio: 10-11:1

Rough Idle

RPM range:3000-7000

recommended gear ratio: 4.11/4.56

Carburetor rating: 650-780

Combination Hi-Performance Use/Bracket"

It's a big cam but it will run awfully is thrown into a stock motor, as you can see the motor has to be a match for this cam and the vehicle needs to be setup for it correctly.

Remember matched components and good tuning are more important than a big cam.
