Basic Header install on Plymouth Duster or Dodge Dart

Sometimes the header may need to be "dinged" in a spot or two for clearance. And, the easiest way is to install the headers BEFORE installing the engine. Good Luck on your install

When I raced a Super Stock Duster in 1973 we had 1-7/8" JR race headers. They were a close fit but still not to bad to install. The cheaper the header the harder as quality control isn't so good. There's two transmission braces that run from the center of the block just above the pan rail that bolt to the bottom of the transmission housing at about 5 and 7 o'clock. Running without them you might crack your transmission case. It happened to my buddy's 69 Dart 340. Use them if you have them. Most guys forget to put them back on. The headers normally work with them.

Awesome job brother. Every Chrysler A-body has got to be saved, period....

[@JustMoparJoe]

Ordered Doug's ceramic coated for the Roadrunner today. I'll get a video install on them! I'm stuck between them and TTI for the purple barracuda. Thanks for the recommendation. Get Ready for a shout out soon!

[@318willrun]

Hope they fit as well for you as they did for me!

[@shaunhoisington3423]

i currently have the cheap headers on my 73 charger... on big bumps they hit of course, but i gave a nice set of NOS 1977 Doug's ready to go in when i get time to tackle the project.. i hope they fit above the center link....

[@aaronpal2955]

I put a set of Doug's in my 67 dart. Wish I had a picture. Had to basically pull the whole motor vertical to get the driverside in

[@axlegrind4212]

thanks for showing the top view of the driver's side header the entire video. do you have the other side?

Headers are a PITA on A body unless you get the " behind the linkage" design. I swapped my 340 back to manifolds after years of dicking around with passs ernger side collector crush etc.

[@will7its]

Headers are a pain on any car nothin but headaches......

[@irishfanrock3494]

Wish it was this easy to install some on my 1970 duster with a 383. I cant see how I'm gonna get any on there. I k ow they say TTI makes a set but I dont see those will fit either. It was originally a 340 4 speed but it's now a big block with 727. I'm wondering if it is even worth it. If anyone has any suggestions on what they did with my same set up please let me know.

[@DubiousDom]

Are your headers coated or will that paint burn off?

[@318willrun]

just painted, it will in time burn off....

[@robbyddurham1624]

I've got a 74 road runner with power everything and ac. I don't think I want to even try and put a set of headers on it. W/o seeing someone else do it first.

[@Reynaga2012]

Mmkay Got it

[@michaelball760]

The Doug's headers on my 70 duster 340 hit the drivers side torsion bar, did you have any problems with that?

[@318willrun]

nope, no dings at all. These cars tolerances vary so much, I was lucky i guess.

[@williamjwarren3735]

I have hooker 5901 for my 73 duster 318/904 manual brakes power steering.I will be pulling my engine to reseal and cam it. Will it be easier with engine out?

[@318willrun]

yes, almost always easier with the engine out

[@mr.k2200]

I’m guessing you have to remove your transmission to engine braces as well? I got some Doug’s headers but honestly I don’t wanna remove those braces lol

[@318willrun]

I don’t know if you “have” to, but I always do

[@keithsims86]

I need ask question I did V8 K member swap on my Duster come found my slant 6 motor mounts bolts are shorter. Are the V8 mounts bolts are longer?

[@318willrun]

you may need longer bolts... just use grade 8 and you'll be fine

[@guidosarducci3047]

I see u don't have power steering. will that be a problem if I do? thanks, I liked & subbed.

[@318willrun]

I've installed headers on Duster/Darts with power steering. Makes the install a little more painful but most headers are designed to work with power steering.

[@guidosarducci3047]

Well, I guess I'll find out. Thanks for taking time to respond.

[@kingairman1]

Did you have to reroute trans cooler lines or put a heat shield around the steering box?

[@318willrun]

no heat shield, maybe small tweaks to the tranny lines

What's an oil filter? Just kidding Good video. What's the paint code on your duster you got there?

[@318willrun]

car was originally silver....

[@dangeroreilly2028]

I recognize it as what Plymouth called Powder Blue. It is the color I had on my '76, 360 Duster.

[@kingairman1]

Are those the Doug high temp paint headers?

[@318willrun]

no, I thought that but they were just coated to keep them from rusting.

[@TheAmericanfisherman]

I have a 71 dart I ordered headers and couldn't make them work after watching this video I regret sending them back what brand do you suggest

[@318willrun]

The ones in this video are Doug's 453. A great fitting header ! And, you can replace the starter without removing the header.

[@MrCareerplanning]

What kind of Headers are these on your car?

[@318willrun]

dougs

[@ezelk1337]

Good video. I need to pull the engine on a 72 scamp witha 318 end a 904 automatic transmission to fix a broken flex plate. Maybe this would be a good time to install headers? I have a question for you about oil pressure on this 318. The oil pressure is good, 40 to 50 psi upon startup. Then after say 40 to 60 seconds later it's down to almost zero. Installed a new oil filter and oil. No change. I shut it down but no knocking sounds. Any ideas? Thanks Eric

[@318willrun]

stock small block mopars should run at least 50+ cold idle, probably 60 psi would be better. Fully warmed up, 16 - 20 psi at 700 rpm idle would be normal. Don't have enough detail on your motor..... Has it been rebuilt? Forabodiesonly.com is a great source of info

[@nathanjames7970]

I own a 1964 dodge 440 with a poly 318 wide block in it having a hell of a time finding some if anyone can help with what will fit would be greatly appreciated!

[@nathanjames7970]

Or if anyone has poly 318 parts for sale let me know 😁😁

[@billward4418]

? I have a 1968 fury 3 318 2bbl what headers would you recommend. Thanks for any advice.

[@318willrun]

First, let me say i have not installed headers on a C-body. Some say the B-body headers will work. I would check with a reliable source like Dougs or TTI just to see on fitment. Then, you can select a header according to budget from there..... 299.99 up to high end headers. As of brand, I love Doug headers, but also hedmans have always been a good header as well for me. Good luck !

[@billward4418]

@@318willrun thanks for the reply I'll check out your suggestion.

[@stevencarter4297]

I have the same engine and headers. I keep having a header leak out of the top of cylinder 3 and 5. Tried all sorts of gaskets and no gasket with rtv. Any tips? Thanks in advance.

[@318willrun]

Make sure the headers is tightening against the head. IF it's hitting the torsion bar below, or some other obstacle that's keeping it from going flush, it will always leak.

[@bradleypatterson4759]

Remflex gaskets is the only thing I use! Worth it I promise!

[@guskovarna3885]

Would this be the same or similar install for a 87’ d100?

the D100 with a small block would be much easier.

I would set aside 4 hours, a lot depends on your cars options and the exhaust you currently have on your car.

@@jayvalentin018 I have not installed those headers. many times you can encounter unforeseen circumstances with headers. The Dougs fit nicely, and that's what I installed. Hopefully your headers fit like a glove as well.
