My 81 W250, when I got it had a stock 318 from 1974, 2brl, with headers. Honestly always thought the headers were dumb on it. Few years ago put a 68 340 intake and 600 Carter AFB and tuned it for max mpg. Headers were rusted out so I stuck early 318 pickup manifolds on it, thinking it wouldn't make a difference, lost enough power to feel and MPG! Same exhaust system. Truck has a 273 with new Hedmans now. Went from a header skeptic to a header user. Four barrel on a stock 318 makes a difference too!
You are so correct. I have played some with the manifold and headers in the dyno, and the results are pretty evident. Doesn't matter what power the engine makes, weather it's 150hp or 500 hp. With smallish primary headers, you typically see about 10% gain in peak and low end torque, and 5% peak horsepower in mild build ups. Using the same mufflers and exhaust pipe size with both. I have found that the smaller primary headers give better gains in mild engines. Typical 1 5/8" headers are on the big side for a mild 318, but still a gain everywhere. For something like 200 or 300 hp the rest of the exhaust doesn't have to be that big either. 2 or 2.25" duals will be more than enough.
Having spent a lot of money on tires since 1979, it amazes me that there is now a competition where people intentionally destroy their tires as fast as they can.
That makes more sense, instead of those guys that spend big bucks on the new tires that make colored smoke. Colored smoke, is that racist ? @@318willrun
I was able to buy and install a drivers side cast iron manifold on my daily driver 73 Duster that you recommended about 3 yrs. ago on a question answered video that you made. Easy access to plugs and no burnt wires. Thanks
Excellent info. Yeah. It seems like it’s worth the trouble regarding fitting them amidst the torsion bars and steering components. Nice to have come pretty solid confirmation of that. 👍🏼 I’m beyond envious of that van and it’s just awesome to see that it’s in good hands.
In my opinion there’s a big difference in power.. My 87 w250 has a stock 2 barrel 318 and it use to be a manifolds and single exhaust.. when I switched to headers and duals it woke up like crazy.. But that’s just my opinion
A long time ago, about 1992 I think, there was a dyno test in one of the Mopar magazines I think HPM, where they tested a mildly modded 440 with HP manifolds and headers and the difference was 75 HP. I probably still have that issue.
As I get a tad older, I will go for reliability over performance. I own a 72 Duster with a 69 340. I use the 69 HP manifold. I custom built 2.5 down pipes and exhaust cutouts. When I go to the track for vintage bracket racing, I run a consistent 13:00’s and that’s ok with me with a car that weighs, with me in it, 3,650 pounds. I will never put leaky headers back on.😅
Love headers on old muscle but my dailys in the 80s were stout sbc....they all had manifolds even smog stuff. Ran just fine wasnt worth the $ for light to light traffic, fwy etc. No way would I fool with headers in a van too much hassle to fix potential leaks, plug wires etc.
Both have their advantages. Manifolds are great for being quiet and maintenance free without burning up wires and parts nearby. For the street where you're 90-95% of the time under 3000 rpm it's a good deal. No doubt headers work. I've used many sets. My chief complaint now is how expensive they are. I remember when you could get Cyclone, Blackjack, or Eagle for right around $100 a set give or take.. Now $500-700 a set. Nearly EVERY set of headers I ever had needed some modding. With 'A' engines it's really more beneficial. Those manifolds are pretty corked up, more so than the 'B' engines. Your van is a great example of using headers. Why not? It's so easy to slip those in there. It's a no brainer, especially when doing a custom exhaust.
@@318willrun That sure is a sweet deal for some USA made headers. I would use headers on my daily driven street vehicles for expediency. I'm on my 3rd exhaust system on my '87 AHB Gran Fury and just had to cobble/fab mig together a wye pipe 2 years ago. Most of the 'replacement' parts aren't available anymore.
I had a 318 in a Dart but with the factory single plane 2bbl intake but a single system exhaust. I replaced my exhaust in the exact same circumstances as you did with 4 into 1 twin system with a balance pipe. I can report the difference was utterly unbelievable even with the stock Ball & Ball/Carter carb. The throttle response, the bottom end torque, the mid range torque, the upper mid range torque, the fuel consumption was so improved I couldn't hardly believe it. If it didn't pick up about 100ft/lbs of torque I'd be very surprised LOL. Next I had made, a custom single point distributor with vac advance and a better curve, that used reliable Bosch 534 points. I had no money as I was a poor first year apprentice mechanic at the time and one of the other mechanics that was a Mopar nut told me exactly what to do and mentioned you'll be very happy with the results for the cost and ease of installation. It was good advice. Made another good improvement to a stock 2bbl engine. The thing is, it went really well on the single exhaust. For a 318 it was great fun first car. I miss that car so very much.
Tried this myself and yes, Headers with dual exhaust is a remarkable improvement on an A Body considering it retained the 7 1/4 Rear, 2.76:1 setup. It ran 120 mph, no problem.
I remember in one of my mopar muscle magazine issues it was the battle between stock manifolds with dual exhaust clear up to the largest long tube headers on a stock 318 magnum engine . better flow from manifolds to shorty headers and between shorties and long tubes wasent much if a difference like maybe 5 HP . Also if you take that insulator gasket on the intake and trace around on the inside and cut out that divider you gain up and flow . charlie that has a youtube channel that does flow tests has a video on modifying that 2 barrel intake you have 8:05
Had a 1969 Dodge Coronet with a 318 2bbl. carb. I added headers and gained 10% fuel economy when driving normal. I did experience a noticeable gain in power and it sounded great.
In 2019 i bought a 1990 dodge van , it had 68k miles. Covid hit in 2020 and the priice of gas plummeted, so i went up country. Form colorado to the imperial sand dunes to the red wood forest and the upper peninsula of Michigan. Fuel pump going out was the biggest problem. If i kept it 60 mph or so i got close to 20 mpg. All stock throttle body injection. Simple to do all the regular maintenance. Always started right up. Was still running when i sold it this past January. Used 1 quart in between oil changes

In the mid-1980s, when I was living in West-Central Texas (Ford & Chevy land) I had a 1974 Dodge Dart, 318. I put on headers and dual exhaust, but it still had the factory two barrel carb. It sounded nice but there was no noticeable seat-o-the pants improvement in speed. It took a four barrel conversion to feel like it was doin' something. It was almost impossible to find speed parts for Mopars in that part of Texas, at that time.
Me , a 1998 Durango 4X4 , 318 230 HP stock . I put on shorty headers , a 360 throttle body with shaved lips on the ventury , I did that , a throttle body spacer . Denso double platinum plugs . The truck would do 130 and give me 24 MPG . Headers can help
I've got an 85' prospector 4x4 with a 318 two barrel I switched to a set of Hooker long tubes (only 250$ brand new by the way) and 2 1/2 inch duals with magnaflows and it woke up power wise very noticeably,not to mention it sounds amazing!! Then added a 71' 340 four barrel intake I paid 25$ for and a used 450 cfm Holley I got for 50$ and rebuilt it and put one size larger jets in the primaries and it's like a diffrent truck!! Next step cam sawp any suggestions on that?? I use my truck as a truck but also like to have fun when I want to so I'm not sure what size cam to go with?? I appreciate your videos I've learned alot!
Thanks! Sounds like you have accomplished a lot on a little spent! Keep the cam close to stock in the truck unless you plan to swap torque converter also. I'd suggest something around .440 lift and 208 duration @ 050
Was thinking about headers on my 318/2bbl Dart. More for the noise. So a little more chooch doesent hurt. I just dont want to fight to get them in there.
I had headers on a 318 in a '70 Challenger with a 2-barrel and although it did seem to have more starch in its shorts, I still thought it was sucking through a bent straw with the 2-V. I wanted an AFB 625 so bad I couldn't see straight!
Telling you right now, theres plenty of ways to make power, but headers are always louder than the manifolds are, i run 3 feet of dual straight pipes and its loud, but not tickets all the time loud
Pretty cool! Another variant, if I may ask, are you running a stock fan, or a clutch fan? If no, I wonder if it would make any noticeable difference on your 60' times with NO fan to rob any miniscule power. Hmm... I like the way you think! Love your videos!
I have always found that to be true. I have always found mpg went up also if you can keep your foot out of it. The spread bore Holly also makes a difference if you can keep your foot out of it too but has to be the mechanical secondaries. I don’t know why. Could be just my luck or just don’t know how to setup vacuum secondaries for some reason. Nice job on the van! So what was the muffler you got in the end? Was it to loud?
Thanks! The muffler was a pair of Jegs turbo mufflers that I had laying around that came with a kit I bought years ago. Yes, they drone some and I'm going to change them out.
I have a c10 with 350 that had headers and true dual exhaust ( no cross over) Went to a ram horn corvette ( 2 inch collector) with y pipe and single 3” through a turbo muffler and runs so much better By the way the dual exhaust was 2” with turbo tube muffler
Headers increase alot of heat under the hood. Problems with vapor lock warmer engine temps. That's with a towing vehicle. Headers open up power. And sound good. But make excessive heat.

swapped 318 single exhaust in 1985 to open very small headers and e.t. change was over a second. You are showing TRUCK Manifolds which was considered better then Production car manifolds
You may know this great video by the way, would those headers fit on a 75D 100 pick up truck with a three speed manual I’ve heard that headers might not fit with a manual? Thank you.
These headers used in this video are for vans specific. I've seen headers on manual shift pickups. I do not know which ones for sure fit. I think the hedmans I put on our truck look like they have room, but you'd have to confirm with them. Good Luck!
Are you running the stock cam? Maybe look at stock 360 2 bb cam. Don't know if 318 2 bbl and 360 2 bbl cam the same specs. If different try 360 2 bbl cam with a 2 bbl 500 cfm carb.
Van? Leave it alone just tune it well In the gas crisis neighbor would buy purple Challenger R/Ts for his dailies. Commuted 150 mi a day fwyin Ca FIrst day the 383 came out, in went a fresh 318, Isky supercam blackjack headers, hush thrush and a well tuned 2 bbl Still sounded good spun tires and got pretty good mpg. Drove it when I Was 13
Lmao 😂 I have a 14 R/T Challenger Classic bought new. I get 13 city and 15 freeway. The gas here is also up to almost 6 dollars a gallon. Newsom does nothing but help us here in CA.
@@thomasthurston6656 Inflation is insane here in Ca never seen anything like it in my life. If I was still working Id have to get a 2nd job just to afford gas for the 1st.
Is your 318 already rebuilt ? Why stop at just Headers ? If you're going to do Bolt ons, go 4 bbl. If you're happy with the results, get another 318 and repiston it using KB Flat Tops, Hughes FT Cam, Johnson Lifters and 65 cc heads. But if it were me, I'd swap out the 318 for a built 360 for your SWB Tradesman.
I really didn't even want the headers on it. It was the easiest way for me to put the new exhaust on it. We are happy with the 318 2bbl in the van ! Thanks!
I said 2 1/4 in the video. But actually it’s 2.5” exhaust.
Nice results, great to see real world results. Thanks
Thank you!

Got just about the same results with my '87 W-150 difference is I used Dakota headers because of collector placement.👍👍🇺🇸🇺🇸

My question is running long tube headers into " super single" exhaust. The truck is a w 150 with a mild cammed 318. Your thoughts?
It would work, sure. Not saying that's the best way to maximize the use of headers, but it will work.
Are you running the stock cam? Maybe look at stock 360 2 bb cam. Don't know if 318 2 bbl and 360 2 bbl cam the same specs. If different try 360 2 bbl cam with a 2 bbl 500 cfm carb.
yes, stock cam. Not sure if I want to do any performance upgrades to the engine. I love the way it runs.

Probably lower 17's would be a fair estimation

yes, they do well

Lmao 😂 I have a 14 R/T Challenger Classic bought new. I get 13 city and 15 freeway. The gas here is also up to almost 6 dollars a gallon. Newsom does nothing but help us here in CA.
@@thomasthurston6656 Inflation is insane here in Ca never seen anything like it in my life.
If I was still working Id have to get a 2nd job just to afford gas for the 1st.
@@gordocarbo Inflation is just the excuse they used to take your money.
👍🏻💯🇦🇺⛽️
Is your 318 already rebuilt ? Why stop at just Headers ? If you're going to do Bolt ons, go 4 bbl. If you're happy with the results, get another 318 and repiston it using KB Flat Tops, Hughes FT Cam, Johnson Lifters and 65 cc heads. But if it were me, I'd swap out the 318 for a built 360 for your SWB Tradesman.
I really didn't even want the headers on it. It was the easiest way for me to put the new exhaust on it. We are happy with the 318 2bbl in the van ! Thanks!
Your Asian too? Hmmm oh aging
Excellent video idea! You’ll be spotting mustangs out there in the 1/8th! 🫡

Headers are noisy
