Quick question, I was thinking of adding headers to me and my dad’s ‘67 mustang. I’ve done a bunch of research on headers already, but I’m unsure if I need to change anything out before I add headers.
No work has been done yet, but we’re looking into a double barrel carb to help with its hesitation.Why do you want to put headers on it? Has there been work done to the engine or something.
Obviously we’d do what needs to be done before putting on headers. Our plans right now for power are a 2 barrel carb and we’re looking into an electronic ignition since we’ve been told that can help the engine with its hesitation.headers are not going to be much help, unless you are going to rework the head by porting the exhaust, and opening up the intake with more than just a two barrel conversion.

Is it even possible to make good power with a 200 6 without spending loads of money? At the end of the day it's still a 200 6. For what it's worth I'd keep it all stock. Just give it a good tune up and enjoy it. If you want it to have more power then start putting together a plan to pull that old 6 out and replace it with a V8. Any V8, but I'm partial to the 289 in a vintage mustang like yours.
Sorry for all this confusion, we’re new to owning a classic car and want to at least get some power out of the 6 because it only has 19,000 miles on and it’d kill us to have a low mileage engine just sitting in our shed. Also, I’m especially worried that doing the V8 swap is going to cost either as much or more than the car is even worth.
I am a little confused....
The OEM components that you are trying to replace have [all] been designed and tested for optimum performance on the engines that they were installed. Installing larger components at the nose and tail of your combination [will] result is less performance unless the engine combination is built to such an extent that it can make use of the extra capacity.
Noobz, I think you greatly overestimate the engineering, power output goals and testing of 60’s Detroit 6 cylinder engine designs. They were usually durable, but power was not really the goal. Economy (for the factory and car buyer), and some torque were the goals I saw.
A cast iron exhaust manifold is far from optimal for power. Clifford has made many improved intake manifolds for the engines without the cast on intake logs. Porting (or replacing) the head will help, as will a turbo and T-5.
A V-8 will help more.
I appreciate all the replies. Everyone seems to say we should do V8 swap and I don’t blame y’all. We’ve decided to start with an electronic ignition as our first little engine upgrade. We got a Pertronix Electronic Ignition Igniter II from CJ Pony Parts.
