big block was over 4 inch pistons.. small block was 4 and under.
chevy had a 400 small block and a 396 big block.
and 2 types of big blocks.. tall deck and standard deck.. both were 427... tall block was a truck engine.
up and coming engine... variable compression engine.. with turbocharger.. do out in 2017 for cars.
big engines will be a thing of the past.. we are running out of oil..MAYBE.
current big engines are considered small block. even over 4 inch pistons.
mostly due to block weight.
my opinion.
as to the gas and diesel...
just like Chevy and Ford
Black and White
Cat and Dog.
pointless.
WHY are there NO gas 18 wheelers??? because.
high torque at low rpm.
higher energy per gallon of fuel
and I am NOT a diesel fan.
just a better platform for pulling.
