I have a 1963 chevy K20 4X4 with a Dana 60 front and a custom extended cab it weights 6300lbs and I have had a 4bt in it since 2000 it gets 24mpg average combined over years of fill ups.
It is similar to a good 350 power wise empty and closer to a 454 loaded pulling a grade, it was a cheaper option back when I built it and I would not change it, but if I were to do it again I would use a 6bt or an LS.
