Hey guys i'm a newbie to the site and I was wondering if anyone was willing to provide a little help. I got a 67' w/ a stock 289. The engine has already been rebuilt and the only non-stock things in it are a K&N air filter and a 4 barrel carb from edelbrock. Now the question I have is can anyone make any suggestions for some headers, manifold and exhaust or anything else that could help w/ the horsepower. I don't really know too much about cams or anything too technical so I thought I'd ask the experts. Any help to appreciated. Thanks.

 

you could look into companies like hooker, and hedman for headers, and edelbrock for the intake

 

if your going to pull the manifold, might as well do the heads while you got it apart......i recommend some afr's

 

If your going to pull the heads, Put some 10 to 1 flat top pistons in. Where does this all stop? Your pocketbook!

 

Yeah right now i'm looking into getting some headers and a full exhaust, possibily flowmaster 2 chamber not 100% sure yet. But yeah I really wanted to start investing in my mustang i've already taken care of the interior now time to add some muscle to it.
