Hey Blitz, I just now found this...Nice work, good to see you're very sensible in your approach...Love seeing that you didn't try to reinvent the wheel on such a tricky manifold, you're just mainly trying to equalize the flow of the worst ports to the best ones...Excellent video for the home porter in us all!!...Major Kudos, keep up the great work!!...
I appreciate your comment! I love the simplifying things, yes there are people who can completely reshape a port and improve it, but the majority of the people (even most professionals) do exactly that Im doing here. I also have a video about porting E7 heads that seems to be getting some appreciation, because I made it as simple as possible without using any of the lingo and confusing words that professionals usually do 🤣. Thanks again my friend!
That looks pretty good I would imagine that flows considerably better and considerably more evenly. I'm considering doing that to the GT40 induction system I have on a 351 in my 89 bronco. I did Port work on the heads GT40 heads before I put them on but I did not mess with the intake and it could clearly use some straightening out and blending. Thanks for the great video.
Luckily for you the lower intake on the 351 has a slightly less severe bend at runners 1 & 5. You can straighten them out nonetheless, but you will have less work to do compared to a 302 lower.
Thanks, this is the manifold that I ended up putting on my brother’s car along with some gt40 heads and a summit brand B303 plus cam, the car did pick up some power compared to stock 😂
Great video! I have been on the fence about trying my own port work. I have a GT40 tubular upper and lower and just got my hands on some GT40p heads. Still hesitant to try my own work, these parts were difficult to come by( I live in Canada) and expensive for me. The GT40 stuff is rare up here. Keep up the videos, I like how detailed and informative they are.
You definitely can! You would have to be very conservative while removing material since the pieces you are working with are very rare and valuable now. I completely understand why you are hesitant! You could also source out an explorer lower manifold cheaply and port that one instead! I think I would probably leave the original lower intact and save it.
id say just get the surface smooth at most if you dont wish to get crazy with it. at least get rid of the little imperfections, nothing to fear about that.
I've only ported one head (4AGE) so I'm a newbie. What advantage did you feel came from doing a trench first (as opposed to opening it evenly as you went) was? Just kind of a guide vs free handing it?
Yes that’s exactly right, it is only a guide specifically on the Ford manifolds so that you can know exactly how much you are cutting to avoid breaking through! Other manifolds and heads without the dogleg you can free hand 😎👍
I broke through bro... obviously im on my truck intake which I believe the 1 and 5 are even worse dog legs then the 2 and the 7 ... then went with epoxy. so seal it again. JB weld. At least now I know it's at basically the MAX. Ive seen the truck dog legs flow at like 160 cfm 😆 then ported Ive seen them flow 250+ So not bad really. but 100 cfm is crazy what a bottle neck haha.
@@MrBlitzkrieg1987 yeah i put some aluminum shavings in it too.. I thought about opening it up more but was worried about losing port velocity being for a van and all need that low end grunt. a TON of metal came out of those and kept the same shape. But again thanks for the video. should help hitting the power goals esp with the plenum matched up and opened for the BBK
I guess you missed the part about some runners flowing less consistently than others… I guess you missed the part about removing a restriction to improve air velocity and reduce turbulence… I guess you missed the entire point or why anyone would do this but ok 👌
On this particular intake it doesn’t. The injectors boss sits on top of the port and the injector bottoms before reaching the port. You can also just match everything around the injector and leave that section alone if you are nervous about that. In my opinion the roof of the port never gets pushed high enough to make a difference on how the injector sits
Thanks for the video, I do heads, but hadn't messed with the intake. I have a 5.0 truck intake dog legs are pretty bad... but yeah it was easy to trench it out... I estimate my wall thickness to be about .125" and I opened them so far to about .66+ more, decent trench to start and can see how much more flush the wall is to the port opening and how the window opened. I am making E7 videos on my other channel .. but not everyone so helpful with DIY people on intake stuff because they run a business.. 5.0 info should be free lol . Have you run or flowed the ported ones yet at all? how are they if you did?
Hello, I’ve never flowed one of the intakes Ive ported. Mainly because I don’t modify all of the runners much, basically just 1 and 5, and the rest get little more than a gasket match. I actually paid a professional to port an intake for me many years ago, and noticed that they did exactly the same thing I did in the video. One thing I can tell you for sure is that the car will pick up some power. Not as much as with ported heads though! I would like to check out your videos, are they in this account you are using now?
@@MrBlitzkrieg1987 funny just noticed the response. Yeah I just looked at a pros video and I mean thats basically all they do is cut back the dog legs .. This is for a built 306 with a decent Lunati 3/4 cam so im hoping for high 300s BHP. I took enough out as a start that makes the inside port wall near flush. I think those runners are just over an 1/8 of an inch so cutting them back 50% or a 1/16 of an inch is safe but could probably go more. But yeah my upper part? theres not much to do. I have the big truck plenum with the dual TB.. all I did up there was open the plenum runners to the lower ( big difference) then opened my TB tunnels to make room for the dual 61mm BBK. But I'm betting doing what you did probably is where its at. oh one second I'll comment with the other account lol
@@MrBlitzkrieg1987 okay this is my more auto related channel for my van lol with E7 head porting. yeah I'm still working on the other head for a full length how to video .. its a bit tricky with the camera to be able to show everything but most of the videos on there are mostly information. Or showing things after I've cut or whatever. I've just gathered as much education as I could to make the best possible heads at home I can without flow bench ( same as the intake)... I had already ported a pair but they need machine work and a couple of holes re threaded so I bought a buddies for 100 bucks and started again. These ones are definitely better just from having more knowledge. I tend to talk A LOT and ramble on but there is a lot of good info. I'm not sure when the full length video will be done, I've got a few more things to film.
@@MrBlitzkrieg1987 Just so you know "D S " is my auto channel lol . I finally got my aluminum cut burr and worked on those dog legs... too bad you cant post photos here.. I may upload and after video on my DS channel but.. I noticed that basically the dog leg when cut back just kind of smoothly blends into the wall toward the top of the intake ... thats basically how far I went... still a TON of metal that came out of there and the pinch is definitely that much more opened. i wish i had a sonic tool so I could know exactly how much metal could come out but its better than nothing i guess
The assembled intake flows 210+ stock. If your heads don't flow 210 or more, what have you gained by opening the intake? Flow balance? Ok but if the heads don't flow it, what have you gained, really??
I have a whole whole Ford Explorer GT40P had an intake set up... And I have a trick flow street heat And take I'd like to know if someone has ported one of those and bolted it on to GT40P heads
Hello, the trick flow intake is one of the best designed manifolds. That intake is made to compliment high performance aluminum heads and will usually flow more air stock than a Gt40 or Gt40p head could do, even ported ones. i would recommend leaving the intake as is unless you are planning to run very large aftermarket heads
Hey sorry I didn’t think about that, I did take noise into consideration, I lowered the volume and fast forwarded through most of the grinding. Due to the nature of this video, some noise was gonna get past my editing.

great video well explain and demonstrated
Glad you liked it! Thanks for checking it out
Love it dude!!! I plan to port my gt40 upper and lower this summer, great info
I’m actually going to be bolting on this intake on my little brothers car tomorrow! I’m glad you liked it
Good job compa!
I appreciate you watching brother! Gracias 🙏
Looks good
Thank you for watching 😎
Nicely done! definitley will see some flow improvement!

Yeah the epoxy will hold well, I’ve seen people use it on cylinder heads without a problem! Like you said, now you know where the max is 👌

Nothing.

does the fitment and placement of the injectors in the injector holes get affected when you did the port matching? Just curious.
On this particular intake it doesn’t. The injectors boss sits on top of the port and the injector bottoms before reaching the port. You can also just match everything around the injector and leave that section alone if you are nervous about that.
