max cam lift and duration with stock set-up?
I have an '86 5.0 HO that i'm running with stock heads and lifters along with flat top pistons. I have an Eldelbrock Performer RPM dual plane intake with a holley 650 cfm double pumper carb. I am currently running a ford racing E303 cam in it now. I am looking for a cam that is going to give a pretty nasty soundling idle with decent driveability and a rpm range of 2200-6500. Any ideas????

Well, from everything I've read on the 5.0 - the E303 seems to be the all-around winner... Of course, I'm a 5.0 newbie, so take that with a grain of salt lol...
In general, there are so many cams out there that it really comes down to what you're planning on doing with your Mustang, and your end-goal (do any of us have those?).

The first question you need to ask yourself is do you want a "narly" sound or do you want performance. If you want a "narly" sound then download a nascar sound clip to an ipod and play that while you are driving around. If you want performance you need to take a look at what the restrictions are in your system.
You have already got the intake, carb and cam done. Unless there are other mods you havent mentioned then there is no use slapping another cam when you havent fixed the other restricions in your system.
Time to take a look at headers, exaust, ignition and your heads. I will leave it up to you to decide what to do as far as exaust goes. It seems like there is a million options as far as the fox bodies go, i will let the fox body guys lead you in the best direction here.
But for heads take a look at this link.

This fixes the biggest restriction in the entire system. Ford has been notorious for making poor exaust ports.
Also what type of distributor are you running? Duraspark, points style w/pertronics, eec IV, aftermarket? Depending on what you are running you might be able to have it recurved to boss 302 specs.

The problem with the really "narly" sounding cams is that the major valve overlap that causes the lopey idle also causes some other problems such as low vacuum at idle as well as difficulty idling, and some even have problems with overheating. I know this because I learned the hard way, although I havn't had problems with overheating myself. I advise you take this other gentleman's advice and upgrade your heads and exhaust first, the difference it makes is truly amazing....

You are running a e-cam with stock pistons?I just installed one in mine same engine(86) and when i rolled it over i had a valve to piston issuse.I might wrong but it went right though the clay or is it just that close to piston.thanks in advance

that's because 86 was the only year the 5.0 h.0 pistons were manufactured without valve reliefs

OP, the E-cam is a horrible choice.
You should consider investing in a new shortblock, something with pistons that are notched for inline valved heads. then get yourself a decent set of heads (if budget allows). If you cant afford them, grab some GT-40 irons and select a GOOD cam. hell, even the TFS1 would be a better choice.
