help my slant 6
If you want 30 m.p.g then stay away from the cam/intake/carb I mentioned.
Instead:
Keep the headers and exhaust system except this time go with a 2" or 2 1/4" pipe max.
I would still go all out on the head.
Look into a cam built for low end torque
5 speed transmission
Drive like you have no balls...
Or you could build it like I mentioned before,and deal with the 15-20 m.p.g you would get in exchange for one bad little street slant...
