First of all, not everyone requires you to pay to have a cam specked out. Plus, anyone who knows their **** is going to take into account EVERYTHING about the current setup you have in order to create a cam to maximize horsepower/torque, etc. I know he's not a sponsor on here, but Ed Curtis custom specked me a cam based on my heads, exhaust, intake, my goals, gearing, etc. I guarantee he doesn't just have three "custom" cams he specs everyone who hits him up. He's a proffesional who designs custom cams to fit each individual application. Anyone who only has 3 different "custom" cam specs doesn't know jack ****.

I believe that you can not go wrong with a custom spec'd cam. As long as you are absolutely 100% honest with your goals, set up, intended usage of the vehicle and have the supporting mods, a custom spec'd can IS your best bet. But again, you NEED to honest with yourself about drivability concerns and desires, HP/torque goals, what octane fuel you can afford, etc., to make the most of your custom can. I see it a lot...customer thinks that he wants a nasty idle in the beginning for a stock engine...I steer him away from it because he can't afford the supporting mods, (heads, tune, exhaust, rear end gear set, valve-train upgrades) he says that he will mod the engine later, blah, blah, blah, I weigh the pros and cons of EVERYTHING that he THINKS he wants, but bottom line is he wants that bad-boy cam SOUND no matter what myself or anyone thinks. I give him EXACTLY what he says he wants and him and his car get beat by a 5-liter Mustang...now I am the bad guy because I gave him what he wanted in the first place...listen to advice from many, do your own research, talk to true professionals that do this stuff for a living and then make a good decision, based on your true-to-power needs. My opinion and or advice is to get a custom cam, as well.
