I have a 6 liter with ls3 heads on it. We caught a cylinder on fire running with the plug out. When the piston came up and pushed the flame out of the plud hole it was spinning and fast. Seeing that was impressive to say the least.

Qcfm wise he is right on target for 700+ hp na

Looks like L. I. Charlie did a good job. I never understood why the manufacturers don't design them to make swirl. I bet we will see his car in the guys from New York you tube racing channels

The reflection on the exhaust is showing you why it's slow on the floor. You're getting a little recirculation from the valve guide. That's probably the noise you hear, at higher lifts the bubble re-attaches downstream but adds a fair bit of drag. At lower lifts there's not enough rotational energy in the vortex to keep the flow attached downstream.

That's quite interesting, it has swirl at low lifts then turns into a straight tumble port.

I hope you tried a radiused margin on that thick exhaust at some point, I guess I will find out as I continue to try to get caught up on videos. Nicely done certainly way better than when you started!

The gaskets dont line up because they put the holes in the wrong spot. This has been going on for a long time now and they haven yet to correct the problem ether. Also sorry im a year late to the party iv been watching from the beginning so if there is an answer in a future video i apologies.

Nice!

Thanks Charles, I'm always interested in the minor changes possible by using open or closed spacers and appreciate the detailed information you provided.

Its hard to explain with out showing a photo but ive also seen those open plenum intakes respond well to a modified 4 hole spacer plate. you cut out the + shape divider in the middle of the spacer leaving an open 4 leaf clover shape or half circles in each corner improving flow ect

Port matching, not gasket matching. Yes ! .030 smaller on the intake, yes ! The moves at the start of the runner, brilliant. Pretty much need a flow bench for that. I really need to get mine done. The visual appearance is only for sales, not performance.

What brand is your valve opening fixture?

The intake side looks great. Can’t wait to see how you fix the exhaust.

Please point me the way where I can buy some of that "superstock bronze" that you mention at 3:00. Also, please point me the way to where I can learn how to apply that. I am very interested in that. I am in the process of porting/polishing a 4.0 head right now. I have not started the intakes yet and have only smoothed the exhausts....so nothing major yet.

I think the wash of numbers on the ported airgap curve is because the intake is better.

do you have to be in the industry to go to pri and how much is addmission?

Me personally, I'll give up 3 CFM to run say 11:1 over 10.4:1 compression ratio, all day every day. A better atomized air fuel mixture is going to tolerate that bump in CR and swirl is what helps fuel mix in the chamber. Anything that helps that fuel stay nice and atomized will help you bump up CR, which ultimately means more power and efficiency within reason.

I like the swirl curve on the Wilson 1" spacer, that one probably would promote more consistent combustion. That would be my pick.

Hay Charles. I didnt know the history of the ford race intake. Shelby or the cobra variation. After looking more...i believe they also used a Q intake with a masive plenum. Sorta like a 2 pc plate. It was used on GT40 cars. If your customer is looking to match the same performance. That intake made by Shelby addressed the imbalance issue.

that last long runner is making you work for it Charles. I wanted to ask about LS cathedral and just super Vic and big single planes in general, how can u port them there so open anyways beside port match and plenum volume is there much in them? like what would be worthwhile for a amateur to do

Stupid question - do you flow test the manifold with a carb/throttle body fitted? My question comes from the air transition from the underside of the carb/throttle body into the runners, especially on the upper plenum long runners. Likewise, with/without the spacer.

There's a vintage Waterbury Hall unit for sale near me, going for very cheap. It is the version before this one. Seems like it would take a long time to do a set of heads?

how much would a job like this cost?

Interesting. I'm in the middle of doing a Weiand Stealth.

Would there be any benefit knife edging the plenum divider without reducing its height?

Looks like an advantage ,,, !

I wonder if extrude honing would help further balance the runners? Nice work and very enlightening as always. "Stay out of trouble." Thanks for sharing. You and DV are definitely helping up my game.

Tough , time consuming work. Good job

what a gagle of snakes! who knows what wet flow is going on in that bunch of bullshit!

Do you try to equalize the port size to each being the same ?(ie… width all 1.19 height all 2.02) Are you planning to bolt intake to head to show airflows thru ports ? Keep up the sharing of your knowledge

I knew it had to be hard to port a dual plane. I know I can gasket match pretty well. Is there power in opening the plenum up as large as it will go?

🔔😎 👍👍👍👍YeeeeHaaaaaw!!!

Hi, I was just wondering if you had an email or a way of contacting you about some flow work… thank you

I have one. $200 excellent bargain, plus the casting is exceptional. I just bought a used 351 Eddy air gap intake and its casting was inferior to the BluPrint.

Attention crap alert!!!!! You cant use any V12 HE Jaguar because they have india made heads and drop valve seats!!!!!!

Thanks again Charlie good video

It's a shame that the Impossible 318 project never materialized after all of the work that you put into it.

We know you can make it talk !

Very interesting tnx Charles

Pathetic technology 😢

? Would the engine draw balance this out a little with an out of the box speed master intake,is there a way to do balance holes ? In an intake

Can’t wait to see what you do because I bought that intake for my 347 build

Crossed over short runners to get some length is the proper way to make a dual plane, that other thing was a shocker.

Charles Servedio, u have got the Cobra intake looking real good!

Hey Charles got a couple of off topic questions . have you messed with using a drill bit and putting slight dimples on the side of the intake valve that see air flow into the chamber ? if so does it work or waste of time and no benifits ? Also unless you already know check this channel out = 1WILDsMoPARtech . he did a several parts videos on how to improve flow on mopar 302 casting heads . im planning on following his mods for my 302 heads 😎 ✌🏁

I am sorry, but I can't agree with this making any low speed torque, especially below 3500 rpm. I have yet to see that large cutout in the divider make any torque, and only a few more horsepower at ultra high rpm. Every dyno test I have participated in with dual plane intakes had a huge dip in the torque curve with that cut down. My EMC engine making over 613hp made the best torque with a regular divider in the dual plane intake at 592hp, and 613hp with single plane intake. I hope you can prove me wrong.

Awesome progression on the manifold! I think most people (me included) underestimate the intake manifold as a restriction on a good flowing set of heads. I also wanted to point out something that i noticed on my 454 Marine engine, the shallow side of the plenum (upper runners) has only like 1/2" of vertical depth from the top of the runner to the carb base ( top left of 3:10 is good example ). My quadrajet secondaries are huge and hang down into the plenum over an inch, effectively blocking a portion of the rear upper runner. A spacer is definitely a must to bring the butterflies up and out of the port.

Where do these come from? I’m a huge 289 guy would love to have a set done .

You Sir are a virtuoso of the carbide. 👍👍

Great video
