Obviously not a new idea but it seems manufacturers don't practice it. One would ask how can you make better fuel economy if your also making more power. Here is how i sprung upon this.
My gf 2008 mitsu eclipse gt puts out 265 hp and 230 lb. ft. of torque, in a 2600 pd car. i might be a little off but thats close, coming up with a 14.4 second car. Window sticker said 25 mpg on highway. Struck me as quite a low figure on this light 6 cylinder 3.8 liter with 10.5 1 compression ratio, most likely static cr i dont know how the manufacturer measures it. I run this thing in 6th gear @ 2200 rpms and acheived 35 to 37 mpg. Thats going up 2 mountains on my way to work.
So here is a quick, light car getting decent gas mileage when u want, and go like heck if u want. In my head the inline 6 can kill this number due to our great amount of torque. In my work at caterpillar i'll rerate guys from 475 horse to 550 horse and guarentee a jump in fuel mileage. The driver doesnt have to gear down to 17 or 16 going up the hill, keeping the rpms down burning less fuel.
As for the ford 6, a sealed, good running engine, throw a carb, cam, exhaust, dui distributer, maybe even some flat top pistons. Get a 5 speed and a rear to match and see if it'll pull the hills without gearing down and check ur fuel mileage. Its not the fix to massive fuel consumption but the parts are available and what u save now in gas will put money in your pocket for more sweet parts.
