Default Need advice on 5.0 ...

I finally got some money together, around $500-600.

My car currently has e6 heads on it for some reason .. e7 plugs don't fit, but e6 ones do.

I already have a pair of exhaust ported e7s sitting in my garage awaiting transplant. I was thinking of getting a valve job and valve springs putting the heads on and getting a cam.

Any advice on what cam, even where to go to get a basic valve job/cleaning/magnaflux done at would be appreciated.

What type of driving do you do with the car? Power adders? Daily driven? Trailer queen? The 303 cams from Ford Motorsports are old designs, but still popular choices. With stock heads (regardless of port work) you're best off not going more than .500 to .510 lift. If you're going to use a power adder a split lift/split duration cam with a 112LSA and around 222/224 duration will work great for you. What are all the mods on you car?

It's my daily driver/weekend warrior, it see's track use once every couple months on average.

It's just exhaust with gears basically. Probably going to go the nitrous route within a year.

Well, I am with Helmut on this one. I know a lot of people that are going with custom grinds, but the E303 is soo cheap ($175ish new) and proven. The cam has the following specs;

Advertised duration: 282 intake/282 exhaust
Duration at .050 in. cam lift: 220 intake/220 exhaust
Gross valve lift: .498 in. intake/.498 exhaust
Lobe separation: 110 degrees
Peak horsepower rpm: 5,500
Peak torque rpm: 2,500
Good idle

I ran this cam with my stock setup and it was great. The only warning I have is this, while you are getting the valve job, upgrade the valve springs. You will be fine with clearances, but if you change the rockers, the stock valve springs are not going to cut it. Other than that, the cam gave good idle and was daily driving friendly.

Edit... You are mass air.... Right?

just make sure you don't also have the 86 flat pistons, some of the very early 87's had leftover 86 engines in them, wouldn't be the first time I've seen this.

My engine is frankensteined, so we won't know what kind of pistons it has until the heads are off. I'm hoping for some flycut forged pistons ... but you never know.

And yes I'm mass air. I saw a b303 in domestic for sale, would that be good, or do you think that might be a little weak?

Yeah, I was planning on getting valve springs. If I get valve springs I have to get all new springs/retainers as well, right? Sorry if that's a newb question, but I don't know

I also hope you find some nice Forged Pistons in there as well!!

B303 Cam Specs...

Advertised duration: 284 intake/284 exhaust
Duration at .050 in. cam lift: 224 intake/224 exhaust
Gross valve lift: .480 in. intake/.480 in. exhaust
Lobe separation: 107 degrees intake/117 degrees exhaust
Peak horsepower rpm: 5,100
Peak torque rpm: 3,300

With the Springs, you can buy a complete kit that has everything. This kits aren't that much more, but I don't believe you have to replace all the pieces, unless there is a problem.
