Small block intake

Wow guys I'm truly overwhelmed at the information posted up so quickly, thanks a bunch. I'm on break at work now, when I'm home I'll go back and try to digest what's been said.
I know this is an A body site, but I figured here would be the best place to find the knowledge about LA engines. I do have a factory cast iron 4bbl intake and a thermoquad from the early 70s I could use, but the thought of dropping a few pounds appealed to me. This 1972 Monaco is 100% stock 360/2bbl/727/8.75. At this time some simple bolt ons to enhance power without sacrificing mileage is the goal, as it's mainly highway driven.

love that wagon , hope you get it running the way you want . Great car , you don't see many that is for sure . so much better than a mini van . with a few modifications it will be the ultimate highway cruiser . what kind of mpg is it getting now ?
