Hysteric..yikes...
Lol he thinks placing quotation marks around made up statements makes them real. He must work for the new york times or cnn...now i'm waiting for the stories where I allegedly piss on hookers and quid pro quo a foreign nation...

RB, I wasn’t going to reply. (Running out of piss and vinegar.) I was asking you questions like I was a dumb *** know nothing about this topic person. Many people come here to read up and learn something. So your comment you made about “your not here to teach me.” Is a sorry full one since that now means others are included in your statement. Earlier you kind of made some insulting remarks. While I’m not personally offended, it was the reason I took the approach and it was a dip from you I didn’t expect.

You gave me (and the forum) a video. Here is mine in return that answers the question more than you did. The big problem here is you assumed and did so on a huge level.

First thing is when the OP asked the question, you assumed your answer was correct and it was, from a certain point of view. What was the OP’s point of view? What parts is the OP using? These and many more questions you don’t know the answer to but yet answered the question as if he was doing what you thought he was doing.

When I repeated the question of how much of an offset of mismatch there was, it was for a reason. Starting with what head and cylinder the OP intended on using. But you know what parts he has on hand to use right?

In the future, before you throw stones and get pissed off like a little girl and ask me to find where you made a statement that you think I said you wise or otherwise twist the words and meanings, take a breath and walk away to calm down.

You yelled at me that I should learn something first and not come back until I do. That is one awe inspiring show of arrogance of one’s high and mighty self. I have bad news for you, this and other forums are here to not only shoot the **** and brain storm between people that have been there and done that but also for others to learn something.

Please proceed to 1.31:00 of this video. And the. Again @ 1.48:00

Wow, that guy knows his stuff! I once had a teacher that said the smartest people in the world weren't the ones that could use big words all of the time, it was the ones that could explain those words in layman's terms so that you can understand what they were saying that were the smartest. This guy can do just that.
 
I never thought that my question about port matching would lead to a 9 page discussion. A while back I mentioned it when guy's have the cylinder heads milled 0.040" and more, how that would affect port matching and intake manifold bolts and if my memory is right the reply was it won't hurt anything. I don't believe that milling the heads 0.040" plus doesn't affect flow.
 
Some here think/come off like you should just take others word as fact and never think about it yourself...
..oh no.. don't question it...just eat the **** served to you and share it with the rest.lmao

The complete picture is the stock head gasket was around .019-.021 thick.
The replacement stuff is anywhere from .039-.054 thick. .040 is really .020 or a hair less in the end after the new thicker head gaskets go on. When you mill .060.. then you'll need a minimum of roughly .030 to be in the range of bolt on 'in regards to edelbrock ootb manifold', though there is a formula of what to mill from the intake face per x amount from the deck. 360 open chamber is iirr .0048 per 1cc and something like .0098 off the intake face for every. 010 milled off the deck...but check that yourself. You can google it. Its everywhere.

It's not just here, seems that's the world we live in today. Sadly. Open dialog and meaningful discussion are a thing of the past, what I say is the truth just because I say it.
Now what do I want to identify as today? :rofl:

What I see is a lot of is this.
"Fred" ridiculing "Sam" as a fool for believing what "George" has to say. Then "Fred" tells "Sam" that what "Fred" has to say is in fact the truth. Usually accompanied with a lot of personal attacks about how much smarter "Fred" is than "George". Followed by personal attacks from "George" about how much smarter he is than "Fred". Then "Carl" and "John" each pick sides and join in.
All justified as trying to help Sam make an informed decision.
Why are so many people angry?

So Darin says that the smaller peanut port increases the average air speed filling the cylinder and increasing the VE? Bam 30 foot pound increase in torque! Who would have thought? This is the port difference he's talking about right?

That's a big difference in size. **** that would destroy all that flow it was getting.......:rofl:

Thanks Darin.

It does but a lot “Depends on the engine combo” as well as what your doing with it. I say this all the time. The things you do for one thing are a great thing but a horrible thing for another build even if ignitions same engine cid, cylinder head and cam. AKA What works here doesn’t work there.

What you’ve posted Reminds me of working on a construction crew years ago, bunch of different companies crews slapping up houses in a subdivision. One crew taking a break looking over at another companies crew on a house criticizing, ridiculing and mocking amongst themselves how that crew was doing things, even though it was legit, yielded the same results. Human nature. Sometimes the posts here are akin to drive-by posting, road rage posting, guys throwing snowballs at the cars passing by, dropping a Boulder from an overpass...:steering:

Earlier you kind of made some insulting remarks. While I’m not personally offended, it was the reason I took the approach and it was a dip from you I didn’t expect.

I’m not here to teach you or anyone else. I posted exactly what I did because the OP has no reason to pick up a grinder. He needs to do a bunch of study before doing that. Like so many others, he seems to think the exercise of “port matching” to be a simple one. Hence why my first post says not to bother with it.


You gave me (and the forum) a video. Here is mine in return that answers the question more than you did. The big problem here is you assumed and did so on a huge level.



First thing is when the OP asked the question, you assumed your answer was correct and it was, from a certain point of view. What was the OP’s point of view? What parts is the OP using? These and many more questions you don’t know the answer to but yet answered the question as if he was doing what you thought he was doing.

The only assumption I made was that you would be willing to set aside your wrong understanding of airflow. You are not willing to do it.

When I repeated the question of how much of an offset of mismatch there was, it was for a reason. Starting with what head and cylinder the OP intended on using. But you know what parts he has on hand to use right?

I addressed this several times, but the PRICK a in you refuses to get it. The correct answer is MAKE THE PORT IN THE MANIFOLD AND THE HEAD LINE UP. Are you not getting that? That is of course, best case. Sometimes you just can’t get that without welding or using filler, which by the way is far above the level of work the OP should be doing. I base that on the original question he asked. To that end, if you can’t get the ports lined up, the manifold needs to be bigger than the port in the head. It’s that simple. And, there is no magic number. It’s not .020 or anything else. It’s the least amount of mismatch you can get. See how simple it is?



In the future, before you throw stones and get pissed off like a little girl and ask me to find where you made a statement that you think I said you wise or otherwise twist the words and meanings, take a breath and walk away to calm down.

Right back at you. You are the one who needs to take a breath and calm down. Arguing with a simple mind doesn’t excite me. Not only are you unwilling to learn, it’s becoming apparent you can’t learn.

You yelled at me that I should learn something first and not come back until I do. That is one awe inspiring show of arrogance of one’s high and mighty self. I have bad news for you, this and other forums are here to not only shoot the **** and brain storm between people that have been there and done that but also for others to learn something.

And I still say go learn something. Like go stand in front of a flow bench for 40 hours or so and see what you learn. In 1 hour you should learn that most everything ever printed in magazines and 98% of what’s posted on forums is wrong. It’s just regurgitated bullshit. You don’t know that because you’ve never done it. Therefore, you and I cant have a sensible conversation. You aren’t capable of it.

I will go look at it. Since I’ve watched most of his videos and webinars several times, I doubt you saw what you think you saw.

Do you even know what that word means?

Dan you don’t k is what you don’t know. You can mill .040 off a head and not have an issue, and you can buy a new intake and have to mill it to get the ports to line up. That is vastly different than what you first asked.

Again, unless you are willing to put in the time to at least get a basic understanding of airflow, don’t pick up a grinder.

Seems to be happening more and more here on FABO.

I think we should have pools on each thread for how many posts it will go before it turns into a **** show .

This guy can do just that.


I explained it as simply as I could. And that teacher was an idiot. You have the discussion at the level of the student, but the goal is to get the student to learn, increase his vocabulary and to learn on his own.

Let me dumb it down some more for you. Do not make the port smaller than the head, ever. The goal is to make the port in the manifold the same size as the port in the head. If there is a mismatch, make the manifold bigger than the head, just enough to get everything else lined up.

Was that simple enough for you?

It’s funny, I watched that webinar live. I also asked a question or two on that one.

The first example you wanted me to look at was the 351C. I suggest you go back and look at all my posts in this thread. First I will remind you we aren’t discussing the 351C or the BBC. The OP a was asking about SBM. Secondly, I said there are a few, very few scenarios where the intake can be mallet than the head. In fact, in one post I said back in the mid 90’s a guy in Arizona published an article about doing that very thing. In that case, yes it helped. But...pay attention here...had the guy used the PROPER SHAPED AND SIZED HEAD he would have made more power.

So the hypocrite is you. I answered a very specific question with a specific answer for that question. Then I suggested you watch some videos to learn. All you did (which is what the sub moronic dolt Hysteric does) was to pull one example of a time when the manifold could be smaller than the head and ran with it. It’s not even close to what the OP is working with.

Now I’m off to watch the second part of the video to see what else you’ve taken out of context.
 
I just watched the second section of the video and you again didn’t pay attention. Darin said to make it line up. That’s exactly what I said. He also said that the air will shear off the sharp edge. I said that very thing. And doing that won’t cause vortices to form.

Darin says a .050 mismatch at the roof is too much and he said why. We’re you paying attention RF? I suggest not, or you still wouldn’t be arguing a wrong point.

Darin didn’t say a damn thing I didn’t say.


For the OP. Don’t do the port match unless you have a better understanding of air flow.

Also, if you use a head with ports that are poorly shaped and have too much cross section you CAN help it (its a CRUTCH for sure) by using a manifold that is smaller everywhere. That’s certainly not the right way to do it. But it’s what you do if it’s what you are working with.

Dan, if you watch all the videos I posted and you think you are ready to do some port work, I’m all for it. Other than that I say pass on it.
 
It does but a lot “Depends on the engine combo” as well as what your doing with it. I say this all the time. The things you do for one thing are a great thing but a horrible thing for another build even if ignitions same engine cid, cylinder head and cam. AKA What works here doesn’t work there.



LMAO! And once again, application dependent. What works here is a disaster over there.

Once again it all comes down to how well you fill the cylinder in terms of quality and quantity. What happens in the cylinder is not always a direct reflection of what you think is going on in the port. The word "combo" gets used as a catch all for when a group of parts do or don't perform like we think they should but I've seen too many "combo's" that punch above their weight according to CID to HP/TQ to CFM to VE to simply dismiss them as outliers.

There's more to this than just airflows to making power but when you only have a hammer or flow bench.......The Smart guys are looking at what's happening in the cylinder and how the port affects that.
Anyway back to the "It needs more airflow narrative" :lol:

More bullshit from the guy who builds nothing. No one is ignoring VE or the quality of what’s getting into the cylinder.

That’s your straw man you set up. Valve limited (almost all inline wedge heads are valve limited and overlap limited) engines are far different from a head like the 351C that has way too much cross section.
 
Also, if you use a head with ports that are poorly shaped and have too much cross section you CAN help it (its a CRUTCH for sure) by using a manifold that is smaller everywhere. That’s certainly not the right way to do it. But it’s what you do if it’s what you are working with.

Is that why that shitty street master intake with its tiny plenum and tiny ports only lost 10 Hp to the airgap at 5600 RPM?

You going there again? Grow up. Any beginning engine builder could build something that would show what garbage that intake is.
 
Nothing you say addresses the FACT that it was only 10 HP down @ 5600 RPM ie maximum airflow demand. Is that because it contradicts yours and others dogmas concerning what it should have made? The fact that it was only down 10 Hp against what is recognized as the best dual plane on the market for smallblock mopars is nothing less than hilarious.
Maybe just another outlier event to be ignored........Or maybe just another one of those "combo' thingy's :lol:
