Actual mileage, about Albuquerque to Las Cruces.
What is the engine displacement?
IIRC it's a retrofit of GM's standard 350 engine. (link)
Is it normally aspirated?
Yes. To drag that huge hunk of steel around with mileage figures like that, you must drive very, very slow.
Though I do try to keep it under 75 due to some overheating problems (I have a busted overflow tank I need to fix).
My 23 mpg car actually gets 28, if I drive it right. But I paid good money for 306 hp, so I use itoften! :-)
True, you can get a lot of difference in the style of how you drive.

Oh, OK. That explains a lot. I could get 38 mpg on that drive. What do you get around town? That’s where I got my 23 mpg figure.
