Stock heads, intake, etc. I have found the reason it runs rough and is sluggish is due to flat spots in the cam. I'm looking at this as a opportunity to upgrade the cam with one that has improved low and midrange torque without killing it on the highway as it will be driven regularly. Wanting a cam that "matches" everything else stock on my engine. I'm interested in this cam generically referred to as a "RV" cam. Been looking at the edelbrock performer plus and the summit racing sum -1102. Any suggestions or words of wisdom are appreciated.

C10 350ci automatic trans I'm thinking you probably have a 307:1 rear? Also not sure how many miles you have on it.
Summit 1102 would be good, I'd use Delphi lifters on any cam I bought.

Or this lunati is one step down from ironangel's recommendation, I really like both cams and recommend them.

Whatever you do if your engine is a high miler replace those valve springs and seals while you have it out. I prefer umbrella seals but to each his own.

You don't want to go crazy on valvesprings with these cams we have recommended. Too much spring can complicate cam break-in, and the stock rocker studs can pull out.
Don't forget, use break-in oil run the engine around 2,000 RPM for about 20 minutes to break in the camshaft. ALSO, break in the new springs. Engine MUST completely warm up once and completely cool off for the springs to take a set. If you rev it up after breaking in the cam without letting it cool off overnight, the springs will become weak and prone to failure.
