Small block gas mileage DD magnum/LA ?

An Easy good mileage la 318 would be a roller block regrinded towing camshaft Advanced 4 degrees with edelbrock sp2p intake 500CFM edelbrock recurved dizzy whole lot of V-can with MSD ignition. Some 2.93 in the rear with a 904. or 3.23s with a 4 speed. or 3.91 with the O/D gear box.

Magnum motors also can give great mileage a well!

My Mild roller 318 wit 3.55 gears gets 14-15 Mpg city driving on the highway around 17-19 if i swapped to 3.23 highway mileage would increase but since i stay of the highways and drive red light to red light 3.55 it is! it currently has 3.91s in it now and i get about 10 smiles per gallon!
