power plus gas milage

I'll agree with awines, decide on a goal first or you'll never get there :) One issue that you'll get into is that most of the performance stuff wont get you to a "wow" factor.
On a slant, "wow" = turbo or head work.

I daily drive a turbo slant. Turboing is not an easy undertaking and it's even harder if you are working on a shoestring budget with scrounged up parts...definitely not easy on gas if you drive like I do :lol:
IMHO the best bang for the buck is a 2bbl intake and a bigger exhaust, and if you have a solid mount cooling fan, switch to a clutch type or electric fan.

With the 2bbl intake ( carter BBD ) and the electric fan I was getting 24 mpg on the highway running about 65mph
