how much hp would I have with my E7 heads with the air bumps taken out and shaved a bit? Could I run this with the B-303 cam or would I need to upgrade the valve springs? If so what so I go to? Could I run this cam and 1.7 rr? does anyone have anyclue how much power I would have? I have a '90 5.0 ho block stock bottom end, Edelbrock proformer intake, and a holley 600 cfm vac. secondaries, all connected to a C4. sorry for all the questions
E 7's are your weak link. I finally just upgraded my crap E5's with Canfield 195's.

well see the problem is I dont have any money...would they be okay im not looking for alot of hp just some more then stock. my plans are to have the heads done with a 3 angle valve job and take those bumps out. would I have to upgrade the valve springs for a bigger cam like the B or E cam? and which one would be better? I wanna put u/d pullies, a cam, headers, o/r h-pipe, and flows what should I be at in hp? Would I be close to around 250-260 rwhp?
+1, just go GT40. By the time you add up all the time, effort, headaches, and money you spend doing that to the E7's it'll be worth it. Just make sure not to get GT40P's, as they require different headers, among other things

dude i told u, u dont have e6 heads ur not an 86, unless u put a 86 block in ur car. u have e5's they are the same as e7's except they are not efi. only the 86 5.0 has e6 heads.
but +1 on the gt40 heads. and the e7's can make power but u HAVE to port them, if u dont port them they wont flow and no power shall be made. if u port em pretty good, go with a trick flow stage 1 cam and that intake u will have about 260-270 wheel. good luck

i would just get a set of gt40 heads the e7's are worthless you should just be happy you dont have e6 heads like mine talk about crap
what if I just added a cam and left the heads alone would I need new valve springs? would it be better then the stock cam? then I could add gt40's later on?

Did you port them yourself or did someone else do it? I went over mine w/ my Dremel....I port matched the intake side first then opened up the runners some. I opened up the exhaust runners and removed the thermactor bumps as well. I agree that GT40's are better, but if you don't have any money you can't get a set, so....... your E7's will do decent ported, but don't expect huge gains. Before porting, I took my heads to a machine shop and swapped them out for a set that was magnafluxed, new valves (and my Crane spring kit), and had 3-angle valve job. This was when I was a noob and didn't know about the GT40's....but I only spent 140 on them.....
I would definitely upgrade the valve springs, regardless of cam choice; but especially over .500 lift!!

why spend 600 to get a thumper job on stock heads when you can just save up a little longer and for 600 and get some of the best heads you can buy with the AFR 165s

Dont look at the ETs or the mph... just the increase in performance before and after, If the Edelbrocks or Trick flows dont seem to be making the performance you wanted.... port work "could" be the answer !! GT40s... and thinking of up grading and spending 1000.00 + in new heads?? Port work !! Those E7s suck!! Port work!!
Check around, see what the new heads are costing AND all the add'l "stuff" to make those heads work ( push rods, headers ect...). Maybe the only thing you need is to have the existing heads Ported and Polished to knock off that 3 or 4 tenths !! or get that extra 30-50 RWHP !! ( HP numbers are heads only and may vary, more mods will equal more HP, the higher the quality of the Ports, less the improvements )

I wouldn't bother with a cam until you've got some other stuff that will really draw the potential out of it (i.e. heads, intake). For the price of the cam I'd just go GT40, if you can find a pre-'97 Exploder you'll have the heads and a nicer intake as well. The other thing about a cam is that you want to replace lifters at the same time, that would be another $130 or so that isn't really necessary right now.

NOT true, my brothers motor outta a 88 Crown Vic, block was markes E6SE, and the heads were too, so i dont know what you talking about really. I agree on not spending 600 on port work, if you, or someone else is doin the work they hell yeah, and ported head is better then a non-ported head, hell mine are ported, and yeah im pushin about 250rwhp and yes new cam= new vavle springs, maybe even with new roller rockers too.....
well I do have an intake and headers right now so would a cam be worth it i mean it has to be better then the stock cam right?
Right... But for the money you spend on the cam, you really won't be able to draw the full potential out of the cam swap until the engine can breathe better, the main component being heads. I would spend the money on the heads first though, LOT more bang for the buck. But that's just my opinion, up to you
^^ [in response to 90lxstanger] I think he's just saying the 86 Stang was the only Mustang to come w/ E6's (and flat top pistons for that matter).
Anyway, if you don't have any money the E7's will be okay ported out. Don't expect to make what you would w/ a good set of aftermarket aluminum heads w/o some extensive (and expensive) port work. Opening the runners some and removing the thermactor bumps is definitely an improvement over stock though and is free if you already have a Dremel or die grinder.
EDIT: What they've said is correct. You will notice some difference w/ the cam, but it isn't worth it IMO w/o better heads. Having said that, I'm running the E cam w/ my ported E7's, but I had the motor rebuilt (hence, everything apart anyway). You'd be more likely to see better gains by slapping some 1.7 RR's on the stock cam.

^Good point, like he said...thats whats been done to mine-thermactor bumps removed, and intake ported matched to GT-40 gaskets(i guess that be basically the Cobra lower?)

man dont argue, that is true ford only used the e6 heads one year, in 86. if ur bros car had e6 heads it was a replacement motor out of an 86 something. why would ford be that stupid and go back to the heads that were perhaps the worst they have ever made.
