Who has before and after Mileage when one of these systems went in place???
There is a nice Edelbrock system for about 2k. I thought it might reduce my gas mileage and provide better driveability and power.
The car is a 1965 with a 1971 302-2bbl. Just rebuilt to stock specs (a slightly more aggresive CAM than stock).
C4 Auto
2.73 Rear Gears.
Average Gas Mileage 16-18 on regular unleaded.
I also have a 1970 Mach 1 351C 4-V with a 5 Speed Tremec. It only gets 13-15 but I drive it harder too.
