Ported E7 Or Stock gt40s

rockylammon · January 8th, 2012, 05:53 PM

a friend of mine with a machine shop says he will charge me only $50 to port my e7's...but i can get a set (gt40) off an explorer for around $100! im going with the x303 cam and know i have to change to 1.6 rollers and the springs in the e7's! but will i need to do the same in the gt40's? and which one will perform better? thanks

06GreenMachine · January 8th, 2012, 06:01 PM

Id go e7s if you want bottom end and Gt40s if you want top end. And you have to remember if you want to get the full power out of the gt40s youl want to get them machined anyway. Im asking myself the same question right now because i have a set of e7s already machined, but idk what i want out of my 85 right now haha.

I don't understand the E7 for bottom and GT40 for top. That makes no sense.... If you have a well matched combo, it will make more power throughout.

Don't waste your money on E7s. The GT40s are a better head overall, and I'd look into a different cam. To be blunt, letter cams really SUCK. A Comp or Anderson grind would be MUCH better.

ALEXLOPEZ62188 · January 8th, 2012, 06:22 PM

Gt40s.
Definitely not a ford racing cam.

baine21225 · January 8th, 2012, 06:32 PM

why not have him port the gt-40s?

Because that makes to much sence.. lol i agree, i have no clue why thats not an option

What title of this thread should be..... port e7 or gt40 ,only difference is 50 bucks

StangBanger302 · January 8th, 2012, 07:36 PM

Wow lol. Spend the extra 100$ on the gt40s and have your guy port them for 50$. But, for 50 bucks, I'd question what kind of job you're getting. The ported E7s would most likely only flow a little more than stock with a crap port job. Hell, you might even kill flow. Just my. 02

FastStang91Lx · January 8th, 2012, 08:43 PM

Gt40's for top end? Yeah those explorers couldn't pull anything but boy would they scream at high rpm

06GreenMachine · January 8th, 2012, 09:56 PM

What im trying to say is that ported e7s make more power throughout the low RPM's then Gt40s do. They both add power throughout the whole RPM range, but the E7s more to bottom end then the gt40s, where as the opposite for the gt40s. You can look at dynos and see that.

Only if you have shit for a combo. A better head will make better power everywhere in the RPM range, with the proper combo. Even with a bad combo, thats a blanket statement that's just not true.

06GreenMachine · January 8th, 2012, 10:28 PM

nah man, im talking a factory bone stock 5.0. The E7s WILL and make more low end power.

*Im an idiot and didnt see he was talking about buying cams also. But i do agree with everyone else you could have a better setup then that.

69fastback · January 8th, 2012, 10:30 PM

Ok, please explain how a better head will make LESS power at lower RPMs?

06GreenMachine · January 8th, 2012, 10:33 PM

E7s with a good port job have better flow numbers then stock gt40s or gt40p's

69fastback · January 8th, 2012, 10:35 PM

Not going to happen. A better head will make better power thoughout.

06GreenMachine · January 8th, 2012, 10:36 PM

Ok man. Im not on here to argue. Im just stating what ive seen. Thats all.

Take it easy

not everyone knows as much as others. I still don't know why people think shittier parts will net more torque though, lmao. "Stock intake would make that have killer torque" oh yeah? What makes torque in an intake? Then they say idk...people talk to talk. That's all.

06GreenMachine · January 9th, 2012, 01:15 AM

So wait you think e7's with a professional machining them have worse flow numbers then stock GT40s? Im sorry but youd be wrong. Now in the case of the original poster, id go GT40s because i doubt the guy doing the machining is a pro, and GT40s you have ALOT more potential with. But im sorry E7's can have better flow then non machined GT40's if you know what you're doing.

That's not what you said. You said E7s are better bottom end, and GT40s are better top end.

Regardless, one head is not going to be better in one area, and not the other. If its better on the top, it'll be better on the bottom.

ryanw · January 9th, 2012, 01:58 AM

But it would be a waste of money to have e7 ported by a proffesional, the money spent on that could have bought a good set of aftermarket head

The only reason id see in porting e7 is if the class of racing some one was racing in required you to have them

ALEXLOPEZ62188 · January 9th, 2012, 05:15 AM

Just get the gt40s. Coming from a guy with experience, my cousin never once had more torque with his e7s than I did on my gt40p heads... Ford didn't put gt40s in explorers if an e7 was gonna pull a bigger boat
