I have A 66 slick with A 390, c6 set up. The gas mi is below 10 short trips hyway maybe 13. Can't aford to drive it much with the price of gas now. I have A crown vic 89 model doner that I can change out the drive trainto the slick. It's A 5.0 efi withAOD.I know it would make a big diff. but how much .I'm sure a lot of you have done this swap . what kind mi can I expect with this swap also what about the preformace.The ol 390 is a strong runner . Kinda hate to give her up.

Where in Al are you?I ran a carbed 302 with mid 80s aod and 3.89 rear gears in my uni for 6-8 months. Got 20+ mpg. FI should get better than that.
