Spray oven cleaner inside the air intake manifold too. It will eat all the gunk out of it. Saw it on Uncle Tonys. Good idea you got there.
I always cut the round "stack" off the floor jet (EGR) and grind away about half of the hex part where I can still screw it back in. Opens the port up substantially without leaving that gaping threaded hole! Love your no-nonsense mods and informative videos!!
Thank you! Yes, that stack will likely not have any bearing on this engine going forward!

What about just putting a plug in and completely blocking off the EGR ? I think that's what I would do, or just get a manifold from a junk yard that is before the EGR came out.
@@bertgrau3934 That's definitely the way to go, but I did that mod on a 440 TQ intake, which they unfortunately never made w/o EGR, they did offer the '72 400 TQ intake w/o EGR, but they are a scarce 1 year deal. A 318 2v intake from the 60s or early 70s should be an easy find, however.
@@318willrun Haha! I get that! But if you wanted to plug that giant hole with minimum flow restriction, it is an option!! Love the channel and believe me, I learn something from your show quite frequently, and I've been in the MoPar biz 40 years this year!!
@@rodneybyrd9516 shhhhh... it's plugged !! Ha!
This is interesting. Looking forward to the testing!!!!
It's got my interest too!!! I've timed and tuned 318 2bbls, but never try to "work" with one like this. Thanks for watching!
Yep very interested in your final results... And you already know the the 318 has always had fuel distribution challenges if you ever started one cold...factory solved that with port injection. Can't wait for more.
We are curious also. No guarantees for our camp !!!! Ha! Thanks for watching!
Looks great, I'll bet it does make a difference.
We're hoping.... in just a small increase overall will make us happy! Thanks for watching!
I have a stash of 2 barrel manifolds I might need to try this out on on one of them. I also have an older version that was used in the late 60's? that is a single plane factory 2 barrel that I have always wanted to try out on something. These old 318s need all the airflow you can give 'em and the BBD carbs run so good its hard to justify a 4 barrel
Thanks for watching! It ran so good before, and outside of our race with the Hoosier Garage van, this van will probably never race again.
That Manifold is a BOAT ANCHOR. It weighs a TON. Get an aluminum dual plane intake manifold. Your Engine will LOVE it.
This intake was to be part of race that is documented on this channel. Thanks
I had trouble with cylinder 8 on my engine always being a little lean. I tried putting new gaskets and various types of sealer used when I reinstalled but always had the same problem. I was forced to daily drive the car anyways and eventually the lean condition made the compression lower in that cylinder. When about the 3rd or 4th time I had the intake off I gave a much harder look and noticed the port on cylinder 8 had a spot that almost looked melted or pitted in a way. I took it to the machine shop and had it planned and checked for cracks. the guy told me that spot was a manufacture defect ad it looked as if it was a "factory repair" where they welded a defect in the corner of the port. He suggested I use the thicker composite gaskets and grey rtv. Said for what ever reason gray seemed to work best. Since then I have had no issues. Just something to be aware of.
Cool! I can't wait to see the results!👍
Us too !!! Thanks for watching!
Loved that video, I really like the way you think outside the box . Simple mods that anybody could do. Wish I was 18 again working on my buddy's Volare with the 318 with headers. It ran well and could of run even better. Thankyou for bringing back those memories.
We appreciate it, thank you !
Very...very cool mr 318, best engine ever made as you know just didn't get a fair shake at performance, i had a 67 notch back barracuda in high school and bought a 71 340 4speed demon, put a purple shaft in the demon and took the stock 340 cam and put it in the 318 2bbl cuda and you could not believe how woke that damn thing up, it blowed everyone's mind, crazy fast for an old 318, one of my favorite horse power story's I've always told but just wanted to tell you my story, love the channel Mopar brother 👍👍👍👍👍✅✅✅✅✅
Thanks! And thanks for sharing your story !
Legend has it that hes still out there in the heat waiting to get into the a/c, thanks as always for vids
Ha! Thanks!!
Great video and channel had a 318 carter BBD in a caravelle diplomat it was pretty tough if not fast
*ALL CYLINDERS MATTER!*

Absolutely !
oldschool tip,when you take the carb off,take 2 of the carb nuts and use them to remove the carb studs..
simply put them both on one stud and lock against each other with 2 wrenches and remove stud..this saves the threads from getting bunged up by some guy with vise grips :)
wink wink
i had a 318 in a lil Dart that ran like a scalded dog AND stayed together. I'd like to stroke a 360 into the 400cu range. like to see over 500ft, i don't care about hp. i like to feel the pull from takeoff. thank u for ur time sir and the tips u bring. never can know tomuch, again, ty for ur time
we appreciate it, thanks!
Don't stroke. All of your combustion and power comes from the top 20-25 percent of the cylinder travel. All you are doing is making the piston travel farther with no more force behind it. Look it up.
@@aperson3268True, but if all he cares about is torque, a longer stroke is the way to do it.
Neat stuff.
Thanks !!!
Back in the '90s I built a 1979 Mercury Capri I use the 302 fuel injection motor converted it over to carburetion.
The intake I used was a factory Ford 302 high rise single plane Aluminum Intake Manifold never seen another one like it.
I was still in high school at the time had no money built the car with used parts.
I drove it to the drag strip getting 25 miles to the gallon I ran a 13.98 at 98mph that was with a used clutch and used street tires.
That's really impressive! Thanks for sharing!
@@318willrun I wish I still had that car
A few things i have done with intakes. The EGR system only affects the engine at idle, above that it has little effect. What the system does is to introduce a neutral (non combustible ) gas so that the engine will function at a very lean F/A mix. Drawback: Those holes & the one fitting are obstructions to air flow. I remove the plug that is under the carb, tap the 2 holes for a pipe plugs and insert a pipe plug that uses an internal hex wrench to tighten. I can supply the sizes if you want. A big problem with those EGR ports is that they can often be clogged with carbon and if you don't plug them a sizable chunk of carbon could find it's way into a rebuilt engine. A manifold off of an engine that has been burning a lot of oil can have a lot of carbon buildup. If you have to clean those EGR passages: Plug both sides with something & pour paint stripper into the large hole under the carb & let it sit overnight. Another method that I have seen on U-tube but have not tried: Use a common hardware variety propane torch & heat one end of the passage until the carbon starts to burn then start blowing air through the passage with an air nozzle. The burning carbon turns into a blow torch as the compressed air is forced through the passage. I have watched the process but never tried it, seems to work. I have seen intake manifolds the had the entire heat crossover passage totally blocked with carbon. On those I start the cleaning process with long twist drills then proceed from there. On the cover plate at the bottom of the intake. There can be a bunch of krud buildup under that. The plate is held in place by 2 little drive screws, screws that have coarse threads and are driven in place by a hammer. They can be removed by grinding a small flat on both sides & removing them with a set of vice grips. They have right hand threads. Tap the holes with 1/4" X 20 tap, install short 1/4" screws or bolts, tack weld one side to keep them in place. That crud can find it's way into a new engine. If you should get a manifold that has been sand blasted it is imperative to remove that plate because there will be grit under the plate. On cleaning parts: Oven cleaner works well on large parts, even engine blocks. On heads & valve covers I use a different method. Get a good 5 gallon plastic bucket & put in a 4 gallon mix of 50% water/ purple industrial cleaner that can be purchased at Lowe's or Home Depot. You have to do half of the head or valve cover at a time but it works great. Drawback: The solution loses it's ability to dissolve grease & carbon at colder temps. You are doing the same kind of engine builds that I have been doing for years to keep my old vans & trucks running. Going to try & keep up with this 318 build. Interesting.
Or just toss it in the bin and fit an alloy aftermarket.
Nice mods!
Thanks!
I have used the huge threaded EGR nozzle and cut it flush then weld an allen bolt flush into it so it can be tightened. Then make a simple block off plate for the EGR valve.
Nice trick!
Damn you work fast. Almost like it was in fast forward!
I had to slow it down, should have seen it in real time speed ...... 😃
Great video!
Thanks!
So, yes there was a single plane two barrel used on the 360s with a larger 500cfm 2 barrel, and then the tbi intakes, you could try one of those. I have a video of porting out a tbi intake on my UA-cam channel, they have quite a bit of potential.
Thanks for sharing. yes, lots of intake possibilities for the small block mopars. On this particular project we are sticking with the original.
Good stuff man 👍
THanks !
Never done it. I have heard of people using a woodworking router & a end mill bit to cut the divider? Your effort looks pretty good
Thanks 👍
Why not a die grinder porting burr? Simple, faster, and can do all the smoothing you want. Plug off those egr holes.
Love the videos. I have a 1979 Dodge St Regis 318 I would love to sell you. Really solid. Runs and moves. Just might need a new 904 lol would love to see more videos done on R bodies
My brother had a '79 St. Regis w/318. Nice riding car! You never know what might pop up on this channel because ........ I do l👀k every day ! Thanks for watching!
I’m interested to see the final results! A friend gave me his old 318 2 barrel intake that he was gonna throw away. I might have to try this mod
Thanks for watching!
Yes you can Port it for 500 CFM 2 barrel Holly & Carter made some good carburetors two barrels. Step that that modification can be done with a gaskets.
Good suggestions! We are sticking with the stock bbd 2bbl for this project. Thanks for watching!
I also perform that dame mode on four barrel intakes
The only other thing I see you can do is
Plug off the egr and heat cross over ports and gasket match the ports
Thanks for watching!
Nice mods. Have you considered swapping with a non-egr intake?
Thank you! In most situations, I would be swapping to an aluminum intake and a small 4bbl. This project, though, we'll stick with the original intake.
There were different models of the Carter bb2 over the the years. Are some better than others. Mine is 1970. Is a newer one easier to tune? I hope you get into tuning them.
I believe there were some that had larger venturi's than others. The newer the carb usually means the more vacuum ports. Thanks for watching!
...so was even the 340/360 2 bbl intake the exact same intake? Too bad you couldn't build a 1.5" spacer for additional down low torque. Still eager to see how it performs!
Thank you! We are eager as well. All 340's were 4bbl, and the 360 2bbl would be an excellent choice but on this project we are sticking with the original intake. We may actually play around with a spacer, we'll see.
Great build! Taking notes as I am planning to rebuild my van's 318. Are you going with the 318 stock heads? Would 360 heads work better or just mess all geometry up?
Thanks man.
Thank You. We are using the factory 318 heads. 360 heads work great, then there is the "larger cc" on the 360 heads that lower compression. You can cut .040 off the 360 heads and they work good. Done that a few times.
@@318willrun Thanks! Im watching at this moment your part 2 on this take. Will go with 318 heads for now, and a summit 6901 cam. All and all, Im following closely your build. Thank you, great content as usual.
@@ChiruStone Best of luck with your build!
What you gonna do with that EGR stuff. Reinstall it or plug it off? Sorry if I didn't catch it. 👍
Thanks for the question, and watching! We'll make that egr stuff a minimalist !!
I did a quick test on a 318 intake, no exaust will get thru if egr valve is closed or capped, and the holes in the floor on both sides of intake act as a balance tube between the two sides. Are you capping off the holes in the intake floor on both sides?
Yes, you are correct ! We'll make it all a non-factor!
I would Match port with gaskets and heads, and weld a plug witouy the scew head and smooth the floor
Good suggestions ! Thanks for watching !
I used a short Carriage bolt on mine
I wonder how much they would charge to do an extrude hone on a two barrel manifold?
I don't know, I'm scared to price it!! Thanks for watching!
Hmm? I don't remember seeing those 2 barrels having such crazy egg systems on them, I'll have to get a Chan to look at an intake from an 1987 and check back. You could also get a tbi I take, or better yet a 360 2 barrel Intake, and it eould.flow alot better.
Yes, this intake is the original for this year of vehicle. Thanks for watching!
I want to see how this turns out.
Us as well! Thanks for watching!
Where did you buy the adapter for the mastercylinder on the d150. I'm in the same boat as you. I need the adapter to put the mastercylinder on the firewall
I actually bought that from forabodiesonly member that happened to be a subscriber to this channel!! He made it himself.
@@318willrun keep your eye open for another one. I need to remove the booster off of my truck.
That will surely not hurt the intake and I believe that it will help it out a good bit . So now that u have that done u can start opening up the ports on it big and wide 😂🤣 boy now that would take forever and the race would be here before you got that thing opened up completely😂 through unless you did have it extrude ported. I wonder how much it costs to have one extrude ported?
It costs more than this cowboy makes ! (wait! I don't have a cow) Let's hoping I just "lose" instead of get embarrassed by the Hoosier garage van 😂
@@318willrun 🤣😂🤣 No cows , now that's not good 🤔 wait I don't have any cows either, only 2 turtles and a so Im a curtleboy 😂🤣 Let's hope that all of these little things that you are doing will net you a big W or at least a big T which will still be a W being you're going in the underdog but I do believe that u will have done enough all over to squeak it out. Are u going to put plugs in the intake holes that pushes exaust into your intake because that cold air/fuel charge should help you out alot plus get those bulky tubes out of the way and plug the holes. Heck you already know all that anyway but Im just babbling but I bet you have took advantage every single detail that could be gotten but even though you will probably not race it again it will still be fun to drive with the extra power 💪🤠
You should look for the 273/318 factory single plane intake. They get even better power from what I heard.
Good suggestion! Yes, a lot of people on different sites have had good discussions on which is the best 318 2bbl intake! As for this project, we are sticking with the factory equipment and seeing what becomes of it. Thanks for watching!
@@318willrun if I could figure it out I'd send a pic of my favorite dodge I ever owned. My 76 B200 tradesman dealer pimped. Factory ev2 paint, shag rug benches/bed with spindle upper and solid panel cover lower walls and a bar with ice box cooler.
@@Mr.mopar71 you can send it through email
@@318willrun what's your email?
@@Mr.mopar71 318willrun@gmail.com
Waiting to see your results.
Fingers crossed!
I have a 5.2 that has two holes next to the manifold on the left side / passenger side, do you know what they are for?
The holes are in the head? or the intake?
If I only had a bridgeport ???
Wouldn't raising the compression just a little be better for a few mileage because it would increase power throughout the whole Power Band without the need for any more throttle notice those are open chamber heads so they can't be good for compression I don't know I don't have any experience with them just curious?
yes, you are correct. We are cutting the heads in hope to gain as compared to before disassembly
@@318willrun 😊
I typed thanks and it put a smile face its not a smartphone its not smart at all🤬
Interesting 🤔
To us as well ! Thanks for watching!
Great idea, but why not put a 360 two barrel intake and carb on it and do that to the 360 intake
On this particular project we want to keep the stock 318 set up. If I was to swap intakes, I'd just use an aluminum 4bbl intake and go that route.
i tried telling him that about a year ago....and use an aftermarket performance holley 2bbl carb...
What did you do with egr holes ?
we will make them a place of non-factor ! Cap, seal, and thanks for watching!
@@318willrun are you plugging and smoothing the holes under the carb?
@@hotrodray6802 it won't have the pipe in it anymore

How much power you gained ?
Thanks for watching! We have no idea if we gained anything yet, we are only hoping. Project still in progress.
Looks fun !
Brother, I care about you and your safety. PLEASE wear gloves when you use an angle grinder or any tool. After 3 surgeries, I finally have use of my index finger after an angle grinder disc exploded and almost cut my finger completely off. It happens in an instant. Just care about you!
I appreciate that, my friend! Safety first ! And I don't talk enough about safety, yes, I did wear safety glasses and always do! Man, I hope your finger fully recovers !!!!
Yup, me too.
A quick slip with an angle grinder exposed the inner workings of my index finger barely missing the tendons which looked surprisingly like thick dental floss.
Guys on the jobs jobsite almost threw up after I showed them.
I lesson learned for sure, a career manual machinist I am and have much respect for things sharp, spinning and potentially harmful but my first few times using the angle grinder were reckless in hindsight.
