"Sure you can stick a big cam in it and it will have a rough idle, but it won’t get out of its own way.

Nothing’s worse than a car that sounds fast but isn’t."

Even with the tiny stock cam in it you'd just about have to drop it off a floor jack to do a decent burnout! Compression and CID are your friends for making power (torque). To get these "little" engines to run you need to look at raising the compression ratio, not putting bigger cams in them when they don't have much compression in them.

The 2800 is dubbed by the Chevy crowd the RV camshaft. It's a "turd" in a Chevy 350 with 7.5 compression, the factory 350/300hp will outrun it at ever RPM and it's only 196/204, .393/.410" lift.

The rule of thumb is to increase the static compression ratio one full point for every 10 degrees more duration you put in it or you loose vacuum at idle, throttle response off idle, low end power, and power in the normal driving range as it jut pushes peak VE up in the RPM range. In the case of the little 350 engine it's already hard pressed to make any power (torque) with those specs so there isn't a magic bullet for a cam out there going to help that scenario......IMHO.......
