The Poly can gain over 60 HP simply by changing from 2bbl to 4 bbl, and that is in the stock configuration!
The Poly I built for FrankyB gets close to 20 MPG on the highway, but it get's worse fuel economy around town than the 2 bbl.
Pulling around a 5,000 lb hunk of un-aerodynamic iron, with 4.10 gears and 4WD makes 20 mpg a pretty nice feat.
