header help

fenderwell vs full length headers. which one would pump out more hp.

the car is a 55 chevy. 327.

Thanks

 

It depends....the size of the tubes and length is more important than where they exit

 

Most fenderwell headers are Full Length. Tube diameter is the most critical for setting the RPM range of the power band length will then fine tune it. That's an over simplification, but you get the idea.
