ok my car has been getting pathetic mileage lately. When i was running my open exhaust the mileage was pretty good but when it go fixed it got alot worse than it had been. anyway i was wondering if putting on a quadrajet would give me back any gas mileage? any thoughts would be appreciated.

 

a q-jet might help a bit, due to the small primaries, but your vacuum secondary edelbrock should be fairly good...

tuning it better would be easiest.
