ported e7's?
 

could i just have my stock e7's ported to effectively with my ecam, i was thinking porting and 3angle valve job. i've taken everyone's advice and not installed the cam yet, but i really want it installed. will my stock heads be suffice or do i really need to get some aftermarkets? tireburner i figure you probably have a good answer. thanx guys this site is great.

That combo works very well. Port the stock intake as well.

Cool!!....another local mustanger here!

Yes, it's been proven the E7 heads can be made to make to make lots of power. I forget the name of the website but (maybe someone here can help me out with that) but they are called "Thumper heads" and this guy ports & polishes your E7 heads and does optional other things with them and thses heads are supposed to really make power.
I don't know if you plan on porting them yourself or what but there is a machine shop in Catawissa called CROSSLEY'S that really does excellent machine work.

BTW, what year mustang do you have?

i actually have 3
an 89 gt blue/silver
a 92 black gt i just picked up
and a 9935th ann gt red/black

i'm trying to slowly mod the 89, on a budget mind you. i was thinking of laubach's in bloom. any idea on them.

Check out the above link and read at it at your leasure. It's got a lot of valueable info. Basicly you want to remove the emisson bump in the exhaust port, take off some of the material around the pushrod on the intake port, and work the vavle guides.

The e-303 cam will work pretty well with ported stock heads. Port the intake too while your in there.

Have you already bought the E-303 cam? If not I would advise aginst it and suggest instead you go with a TFS #1 cam. The e-303 is a tollerable cam and performs fairly well, but it's out-dated and often seems to cause a idle problems.


While it IS true that Thumper heads, Power heads, etc DO perform well for what they are (stock heads) the price puts them out of the question IMO. Power Heads are like $650 bucks for CNC ported stock castings. If you hit up the "For Sale" forums on some stang boards you can find used aluminum heads for around that much money, that flow much better.

Hell, Drew (FiveOhPatrol) picked up a set of BRAND NEW Pro Topline 200cc aluminum heads for $800 bucks from Summit (they were on clearance)

I cant remember the exact website, but if u still want the thumperheads website I will get it off my computer tom...at work now.

Lots of guys have run his heads with my ported lower and made very good power - 250-260RWHP and 300+RWTQ.

IMO, dont waste your time on E7's. I used to run ported E7's and I had more money in them than I have in my canfield aluminum heads.

I had them ported, polished, milled, 3 angle valve job, and trick flow springs. They performed well but pale in comparison to aftermarket aluminum heads.

JMO,

Re: local stanger
 

I'm pretty sure Laubach's machine shop is no longer. I take my machine work to Crossley's. He's good and good on prices.
Terra's speed shop is also good but expensive.

I agree but he's on a budget. I don't know his financial situation but I'm sure a set of Canfields would be way over budget.

I had my stock 351w heads ported/ploished, new guides,springsinstalled, and oversize stainless valves installed for a little more than $700...............not bad

For $700 you can find used, low mileage aluminum heads all over sites like the Corral, that will walk all over a set of ported stock heads.

No doubt that aluminum heads are superior than irons but I wouldn't feel comfortable buying a set of used heads on the internet.
My $700 got me fresh heads, new parts and peace of mind that they will last me a long time.
I'm sorry but if you are going to buy heads then buy new ones....iron or aluminum or have the ones you have rebuilt.
Paying $700 for used heads could get you $700 worth of junk.


bailey_57 , your best "bang for the buck" would probably be the thumper heads since you are on a budget.

ported e7's
 

thanks guys, i am in fact on a very minimal budget, from what i've been told the e cam i have will work great for now with ported e7's. i'm putting off on the afr's until i have the bucko's.:D

I also have debated buying used heads off the internet. Seems to me like a risky chance to get a set of $700 paper weights.

You just have to buy heads from a reputable person. You wouldn't buy a car from a shady used car dealership would you?

I like going fast for the least amount of money.

$600+ bucks for ported stock castings is a 100% total waste of money IMO. I just can't justify in my mind spending that much money on STOCK heads when there are so many more options that will net you more performance for less money. Ask any hardcore stanger here and they'll tell you the same thing. (dark 5.0, fiveohpatrol, bos55 come to mind)

The money you save can be put towards other mods that will ultimatly make your car even faster.

If your gonna buy stock heads then talk to Jeff Chambers and get yourself a set of GT-40P heads and port them or have them ported. That will save you several hundred bucks .






-Josh, aka the tireburner

Come take a ride in my mustang with ported stock heads and then tell me I wasted my money.
We are not all born with silver spoons in our mouths and can afford "Canfield" heads....oooohhhh:rolleyes:

Before I built my engine, I had a goal in mind, bought the parts, assembled the engine(myself BTW) and ended up with a product that was much better than expected.
I say that's money well spent!!
Sorry dude but you kind of pissed me off when you started telling me how I wasted my money...blah blah blah
As far as buying a car from a "shady" used car person, how does anyone know he's shady until they get the car home and realize about a week later they bought a POS?
I'm happy with how my engine runs and the money I spent on it and that's all that really matters.

BTW.....I'd love to hear you tell they guy that builds those THUMPER heads that he's wasting his time with STOCK heads and tell all the people who bought his heads that they too also wasted their money.
Hell...while you're at it, you may as well tell TMOSS that he's wasting his time on STOCK lower intakes.

I am not saying he should dump the money into his stock heads. I believe that with the vast knowledge on this board, people could help talk him through a few small self porting steps that could really wake the e7's up. Then he would have very little money in the e7's...but have a better flowing head to compliment the cam.

Anyone can buy a set of aluminum heads and bolt them on. He would probably rather do that. But y not teach him how the head works....what it is in his heads now that is holding him back....and let him work his way to the aluminum heads (when funds allow).

With a set of E7s that I ported, my car ran 12.70s @ 107. Now with the car gutted, a stock motor runs 12.40s @ 108. Just for the argument I woud love to see another junkyard motor with "Thumper" or "POWER" heads on it with cobra intake and a B cam. I am currently porting my Alum heads. I had a professional do one cylinder and I am duplicating the rest. This port job is way more shaping and changing to the runners than I ever did to my E7s. I would love to see a good set of E7s on my car now. Matter fact this has got me thinking about backing up the stroker for a few more months.

Some of my ported stock intake/Thumper customers have run those exact numbers.

Ding Ding Ding Ding - we have a winner!

Reshaping ports in an intake or a head is where the REAL power comes from, not just going in and hogging the runners out larger.

Whoa dude, calm down

I never said stock headed cars were slow. If you look at my sig my street/strip LX you'll see it has massivly ported GT-40 irons. However I only have about $375 in them, including the cost of the heads.

None of use were born with silver spoons in our mouth. I only make about 9K a year. This whole arguement about aluminum heads has been about SAVING money and going fast for less money.

Agreed

If you want to spend $700 bucks on stock heads that's fine. Lots of people buy Saleens every year. I think they're wasting their money too. I like going faster for a cheaply as possable, if that dictates buying used heads, so be it. The vast majority of the people on the web ARE good people.

Agreed, it's your motor, build it the way you want. I am mearly offering my OPINION in this thread.

I'm quite sure he's not wasting his time, I bet he's making a KILLING off of these heads. Thumper heads flow very well..........for what they are. But I still can't justify spending 600 bucks on stock heads when you can buy aluminum heads that not only flow better out of the box but you have the option of porting them and flowing even more. The Thumper heads are maxed out. For a lot of people just wanting a mild 306 mustang the Thumper heads are fine, but for hardcore people really looking for some serious speed they just won't cut it.

I never said anybody that had their stock stuff ported is wasting money. The heads and intakes on BOTH of my cars are ported. I'm just saying that it doesn't make sense to spend $700 on stock heads when you can get aluminum heads for the same price. Sometimes you can even get NEW aluminum heas for just a tad more. FiveOhPatrol picked up a set of Pro Topline aluminum heads for $800, BRAND NEW, from SUMMIT.

I hit fletch's carbed mustangs and looked at his flow numbers for iron and aluminum heads... those thumper heads and their 218/154 flows outdo a lot of the milder aftermarket and gt40 heads and do darn well for the $600 they cost. Plus everything will bolt right back up since they are, after all, stock heads.

Anyhow, after doing my own "porting" for a week or two, I say it is very much not beyond the abilities of the average joe. I've been using a drill and a rotary file on an extension and using the way too soft blue grindstones (at least it's hard to make a sudden mistake when you have to grind for 2-3 minutes to get an area smooth). Go for it. It will cost you a bunch of time but only $50 max in drill bits and maybe a burnt out drill. Have 2 drills and let one cool while you work with the other. Every once in a while, stop and switch to 80 gritting the runners and let both cool.

Most of all, it will be FUN and you'll feel like you're really taking the project in hand.

Good luck!

Josh, We love you man.

I had 700 bux in my E7's

I bought the Canfields for 600 bux

I couldnt get more than 200 bux for my E7's after all that freakin work went into them.

Last but not least do a google search on the thumper heads and look at the page after page of complaints;)

I would at least get some GT-40's.

I have been selling intakes to guys who used Thumper's heads for years and never heard a complaint, so I followed your advice. After 10 pages of Thumper hits with not one complaint on Thumper of Orange Park, FL, I quit. Lots of other "THumper" hits including a Mazda head guy, but not one on Mike Shultz (aka Thumper of Orange Park)

I think that the bare castings of the E7's I had were thumper heads. I belong to many sites. I dont remember wich site I was on when I was defending the Thumper heads and then someone posted a link to a massive complaint page. Basicly they were saying that the bare heads are good but the thumper valve train sucks.

I use to sing the praises of ported stock heads until I upgraded. Now I see I was just wasting my time and money.

BTW I seen the other day that you also post on DWFstangs.com....Seems to be a good site to buy and sell stuff on.

You are correct TMOSS I was wrong. I confused Thumper heads with Power heads.

:o

So here's a question:

Could an individual with oodles of time and common porting knowledge (and some fanaticism) end up with their own home made "thumpers" or are these CNC/computerized machined and out of reach for the home-porter to replicate functionalitywise?

And on that note:

Does the lower valveguide _ABSOLUTELY_ need to be there for 0-5000 rpm applications? I was thinking to just smooth the entire runner down and take all guides/bumps out altogether and have a smooth tube all the way in and out and then HOG out the intake and exhaust ports till it's glass smooth. Am I begging for disaster without guides or should I be ok?

I ported a set of stock heads for a buddy of mine. It's really not that hard. He made 365 ponies to the wheels with 8psi and the stock cam. I didn't think that was too bad (not to mention it was my first port job.) I would say if you're looking for more power on a budget...do it yourself. If you're willing to spend 600 bucks on stock ported heads then save a little longer for better heads.
-Ryan

thanks guys
 

you've all been helpful, i found a buddy with a set of e7's off a 94 gt that had new springs and a 3angle valve job, i'm not sure what else. for $200 bucks is it worth it? i really want to shove in my ecam(new in box still) without f'ing up my car. eventually i plan on afr 165's or 185's with an paxton. but right now this seems like the ticket. what do you guys think? BTW do you know anybody who wants to trade and aftermarket intake for a set of weld draglites. 15X8's in the rear, and 15x5's up front one of the skinnies is curbed pretty bad, i don't know if its repairable.
thanks josh and everybody else you guys are really giving me an edumucation
