Can someone help help me understand choosing a better cam over stock? For say maybe a 1978 street 350?

I will take a stab at it.

Stock smog motor with stock heads and stock compression - no other real mods? If so, you can use a Comp 268H. That is a default for that application. It works. Headers, converter and intake will help some but are not mandatory.

If you have more mods than that you will need to provide a lot more info. It is important to match the cam to the application and the rest of the setup.

I'm not saying to quit looking right here, but I second the Comp Cams 268 Series for a stock application... I had a bone stock Nova with an anemic 305... Decided to start with the cam... Wow, relatively speaking it really woke the car up... Following that, I put a four barrel intake, spread bore holley with vacumn secondaries, headers and full dual exhaust and had a nice lope with plenty of power. Ported the heads and wow... what a difference it all made... It wasn't a 350 but it had plenty of power at the time... Best running 305 I ever drove...

Street small block Chevys love any brand cam with 220 intake duration and 230 exhaust duration on 110 lobe seperation angle - 112 LSA is OK too.
