Glad to see you're an honest man Curt. When I hear claims of 20
plus mpg with a stovebolt, I have to laugh.
I've put 15k on my truck now and kept a log of all the mileage.
The average is 14-15mpg. The stock 216 engine had complete
rebuild by a major engine shop that is a large marine engine
rebuilder. Original stock engine had about 55k on it. The
mileage dropped off by about 1 to 2 mpg after the rebuild.
Can't explain that other than it was bored .030" over. I was
getting 15+ before it was rebuilt but pushing a lot of oil.
Oh...SM420 with a 4.10 HO52 rear.
