318 MAX fuel economy builds?

Maybe if they didn't castrate the 360s with dished pistons, huge combustion chambers and abysmal CR maybe I could feel better about 360s in general.

I am so tired of the 318 bashing, around here.

(my own experience anyway) I've had better service out of 318s over 360s. Also in my experience a 360 is more likely to be caked with sludge when the valve covers are pulled than in a 318. I don't know why that is. Just MY experience with them.
I've seen cars with big blocks easily out do 360s if mileage is a concern.
Ive also had Dakotas with 3.9s and otherwise identical Dakota's with 318s and the 318 was more likely to drive past the gas station than the 3.9.

I knew a guy a few years ago who had (sorry GM content) a 70 3/4 ton truck with a 292 inline 6. He's had this truck for years. Always complaining about mpg, no matter what he did with it. He got the hair brained idea to put a 455 in it out of an Olds wagon and was quite surprised mileage actually got better.... same rear end, same tire size.
So yes a bigger engine can mean better mileage and more power as well....
I've been driving since 83 and have NEVER owned anything but Chrysler products in my life. And not interested in starting to buy something different now. But if a vehicle came along that I otherwise liked, was in reasonably good shape but it had a 360 in it vs some other choice I wouldn't let that keep me from buying, but they're not my 1st choice.
