I'm confused??  I have used 231 cubic inches per gallon for many years, when
did it change and why??

You are absolutely right Mr. Hogan. I was just trying to find out if
anybody reads this stuff :-) Just kidding. I don't for the life of me
remember where I got that bad number. I checked my reference chart and
it 
was 231. I checked my TI-86 calculator and IT was 231. Looks like
231 is it. 

Maybe that is an imperial gallon. Yes that is it. 277 cubic
inches per imperial gallon. Those English can't do anything right :-)
