318 MAX fuel economy builds?

360? High mpg? Does not compute. Sorry.

In my case on my b body fury's 318 it will be getting a lean burn ectomy as it was starting to act goofy the last couple of years of crusin season (about 1500 mi/ year. A whole different engine is out of the question in my case, it may be a lil slow off the line but it'll cruise 70 happily all day long, as is, is really good on gas, (surprisingly so), and is the original engine in the car which has 56k original miles on it from new..... No way is that engine coming out of the car.

Larger engines don't necessarily mean more fuel plus he's looking for a power mpg balance, say it takes 20 hp to move your car down the road, it's gonna take a narrow range of fuel and air to make that 20 hp, so it depends on how efficiently you can make 20 hp at part throttle neither engine 318 vs 360 is using vastly different amounts of fuel and air is why you don't see huge differences in mileage.
