I was looking online to purchase some headers and I am not having any luck.

1973
Ambassador Coupe
360

I looked at Jegs, Summit, eBay and a few others with nothing listed.  I know the Matador is similar, but the front clip is shorter and I don't know if the steering box etc would be in the way.

Does anyone know what will fit this application?

Thanks in advance.

Anyone?

Crickets!

Has nobody ever put a set of headers on an Ambassador?

It looks like the Headman 500-98310 fits a wide variety, but of course the Ambassador is not mentioned when you search them.

I used the Headmans for the Matador on my 69.  They were the best fitting set of headers I've evr used.  Didn't even have to ding a tube.  That is a 1969 trunnion car. They should fit fine on yours but I can't guarantee it.  You have ball joints upper and lower.  Also a different trans.  If they fit a Matador, they should fit yours.

Dougs lists there #D109 for 66-69 Ambo's. I don't know Ambo's that well so I'm not sure how different a 73 would be. Confused

I found the link to Dougs catalog.  Thanks for the tip.  I will try to find out if these will fit my '65.  Anybody know?   Also how about some opinions on this upgrade.  Although they are not cheap, by any means, do the AMC gurus think they are worth the bang for the buck?  Sound and performance...slim

They won't fit the early 57-66 V8, you have to custom build headers for those vehicles.

Looks like Lucas is right.  Total number of headers available for my 65 seems to be  ZERO.
I'll keep looking...slim

If I eventually get around to fabricating some for my classic I will put some photos up and possibly a file to get the flanges laser cut, it's a long way off now though.

Did you ever get those headers installed? I actually own a 72 and a 73 Ambo and I'd like to put headers on both but I'm running into the same problem as you. Nothing lists the Ambo on the details.

if you have a 70 and later Ambassador or matador  use the
cast iron free flow headers from the 390 or 401 engines and
save yourself a lot of problems
grind and clean up the header to match the ports and they will make as much or more HP as a leaky ill fitting header
and any good muffler shop can make the  front pipes to the original
AMC specs if you do find a set of headers put them in the trunk
and enjoy driving  your car  , I know the hassel with headers from past experiance

The advantage of headers when connected to a full exhaust system is mostly neautralzed by the exhaust system so if you just use your freeflows already on the car with a low restriction exhaust systems the performance difference will be negligible. Where headers make a significant difference is when you they are tuned and run open.

My plan is headers and straight pipes out the back. The Ambo is just too quiet sitting next to my 67 Rebel. :)
