Headers for Ambo

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.

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.
