Hello, I was getting ready to order a set of Dougs headers for a customers car (a 1972 Plymouth Duster with a 318 magnum engine)
In the foot notes is says that the headers won't fit if you are using a 727 or in my case an A-518 transmission. Can anyone tell me if they have a 727 behind there 318-340-360 in there A-body and it fits o.k. or?

D453 - Doug's Headers for Dodge/Plymouth Passenger Cars


Notes:

.Fits with Mopar mini-starter 312-P5249644AB.
.Does not fit with 727 transmission.

does not.

I'm using summits full lengths install was a pain. The headman shorties are nice too, nice plug access compared to the full tube summits.

Might be time to sell the 4dr 4spd 3.23 323". might dump it. Get a honda fit, Xa, or other tiny car.

I also saw the Hedman Hedders..
#78056 - Hedman Street Hedders ...
in summit...does anyone have these on there A-body?

I have the Heddman headers on a 72 318 duster. power steering, manual brakes, 904. Bought them used pretty cheap (i thought). Guy i bought them off of said that a friend put them on and then decided not to run them. Was a dent in a tube,told me the pitman arm hit there. What i found when i put them on: clearance around steering box was fine, #3 tube hit collar on steering column, tubes were very close and/or rubbed on center link, pittman arm , idler arm. up against RH torsion bar. I thought maybe it was just the wrong application. Looked them up and found that they fit A,B and E bodies so they are correct i guess. Maybe i just got a bad set. the tubes that go under the center link will be pretty close to the ground. Something to deal with, with these and the Hookers. I am big block B body guy, this is the first small block A body i have really messed with. It hasnt been too nice to me so far.

Thanks for your reply on those. He already has a set of Hooker competion headers on the Duster and the headers hit the steering linkage in a few places. I guess the Hedman hedders are no better. I guess we might be stuck with buying the high priced TTI hedders...$$$$$$$$$$$$$$$$$$$$$$$$$$

ask crackbacked.

He just posted somewhere that a Dougs A-body fitment listing was wrong. I don't remember the details though.

I looked but I couldn't find his post

D453's fit A's with 727 transmissions. I have two friends driving cars with just that combination, SB/727. Keith9192 over at FABO is one of them.

They also say they don't fit 73+ spool mount cars. Hogwash, they fit fine.

I have the D453's and a 727, fit is great. You need a mini starter with the 727's. I believe that is the only requirement for the D453/727 combo.

Thanks Bob and Tom... for the posative information on Dougs and the pictures mean a lot too!
Where is the best place to buy them Summit? Jegs?
Gary

those are some good looking headers. the flanges look a lot thicker than my hedmans.

I think i have Heddmans on my 68 Dart 318/727 , plug access is good, ground clearance suck's.

Good morning!
I hate to ask but
Tom...can you take a picture of the ground clearance that you have with your Doug's hedders?

I would also like to see what the Hedman hedder ground clearance is like.
Thanks Gary

Ground clearance will be affected by ride height.

Tom

FWIW I have a deep 727 pan and it and the headers are same height. This is an old pic with the 904 actually. I can snap better ones if you need.

My car sits pretty low and have navigated my fair share of speedbumps with them successfully.

Thank you Tom,
They do look good on there. If it's not too much of a problem taking a picture of the passenger side of the 727/header clearance that would be great!
But I understand if it's going to be a pain...
But Thank you for all of your posts/pictures you have sent.
Gary

Here's some pics I grabbed for you.

Tom

I'm liking the look of those headers for my '74 Duster, $580 from Jegs.

Damn! States will not work with column shift, can anyone chime in on this?

Firstoff Toms car is a e-body so fitament is going to be different,my buddy recently put a set of Dougs on his '70 318 dart they come real close to the oil pan,and i believe he had an issue with the steering column..when he saw how nice my tti's fit he wished he had bought them instead...
