LA ( Medium Rise 2×4 Intake )

Medium rise? No.

Edelbrock made a dual plane dual quad. 2 versions. 1 for the early small screw/odd angle heads of the 273 and then the later normal 318/340/360 head bolt angle.

Offenhauser made a low level split plenum dual quad. The carb pads were low and high as per there description. The runners didn’t move. Just the carb pads.

Ten 4 thank you
So both makes were low rpm like 6500 max ??
