I currently have Sanderson shorties in my 67 f100. The collector on the passenger side is right up against the cab mount/firewall, which makes tightening those bolts extremely difficult. Looking at long tubes online and while there are lots of options for 73-79 with 460, I'm not sure if the 67-72 engine bay and front frame section is different. L&L makes swap headers for this generation also. Looking for the best fitment, even if that means more money. What is everyone else using?

 

It depends on if you have the factory frame mounted auxiliary fuel tank. If yes, forget the long tubes.

 

Nope, just have the in cab tank.
