Do a compression check. It'll help to see the condition of the engine as well as tell you whether or not the camshaft is way off from spec. I have a diatribe on my web site Tech Section called "Dot to Dot" about accumulated tolerance stack up and why EVERY camshaft needs to be degreed in....
Do the basics too.... Check all the normal things, timing, fuel pressure, plug gap, meter voltage and throw a vacuum gauge on it. Simple things show a lot.
In terms of power levels... you should see 290 RWHP on a decent Dynojet... give or take.
As for the F cam suggestion.... Now I'm scared of that shop. They're well known if that's Lidio's place but an F cam? WTF ?? Pure stupidity.
