GAS Mileage with a 4bbl INSIGHT, ANYBODY?????

I am just as sick as everyone else with the rising cost of fuel. I have been contimplating buying a gas saver?????? Or build my 72 Z that i Have stripped at my shop. I plan on putting a four barrel(390cfm?) on it with the possibly a cam.

I have no Idea what these things got stock, I know a lot of guys do the 4bbl route.

What ever data I could get would be great!!!!!!

You could spend $400 on a manifold and carb, never recovering the cost in gas savings. I once had a Chevelle that got 6 mpg. I said it then and I say it now, when it comes to fun FTMPG!
