Daughter needs Gas mileage from 273 commando

Rumblefish360 F.Y.I. - Not just because I have one, but the Offenhauser 360 split plane Intake is the best Intake I have ever used for bottom end torque. I bought it for this car but bolt angle was a problem for me.(found this out later) "Wallowing" out the bolt holes to make it fit was not an option for me. I was into offroad heavily years ago (still love it) and it was THE Intake to have along with a offroad Cam and Kit on ANYTHING you wanted torque low down. you can tell Seat of the pants difference with intake only change. Hope that helps, Tim
:D
