360 or 318 which would you rather have???

really now. so what your saying is a slant 6 in a 3500lb car will get better milage then a 318/360 in the same car?

on the hyway, yes.
more cylinders to feed, don't care how much work is being done and with how lil throttle compared to this or that.

if the slant nets 25 mpg and the 360 20mph, well...it doesn't ake a genius to figure that out.

and skip the cars, lets pretend they are mounted to a radio flyer.:toothy10:

better yet, give them both a 2 gallon tank of fuel to sit and idle on till one runs out of gas.
