"I’m sure a good many others here will be looking very forward to seeing you build thread on making a lot of power and getting high mileage. (Notice how I left that as a very broad ave. for you to travel.) Heck! If you can double the factory power output and retain the factory EPA rated MPG, I’m all ears!"
That's the thing...I don't care what MPG I get. But on the flipside, I also know that if I have a engine put together right, it'll get pretty good mileage. BSFC and all that.
Another massive step in MPG is to simply have EFI. The ability to control spark and fuel based on load is tremendous.
On my 66 Fury, a full-on loaded pimp car with power vent windows, I had 4.10's in back and a 526" Hemi under the hood. I didn't care at all about MPG, but it would still turn 17 MPG on the highway. I drove the car on 3 separate 350 mile trips so it didn't happen just once. I was also running tons of timing advance on 10.5:1 CR.
The MPG is icing on the cake. View attachment 1715579132 View attachment 1715579133
