guess you have to define cruiser better. my 360 ran 12.17 on super pump gas and i drove it on numerous 2+ hour highway cruises. now it only got about 8 mpg and even with tall tires it would be screaming at 65 mph. but the car did it time and time again. was a real simple combo too. 360,eddy heads, 508/292 mp cam, dynamic 9 1/2" converter,904 trans and a 8 3/4 rear with 3:91 gears. i constantly bitched i wanted a better cruiser. then when i finally hurt that 360 i installed a stock 74 360 and put my rpm intake and headers on it along with a stock converter and a 2:94 gear and love driving the car more now then i have in years. i can cruise at 80 mph at under 3000 rpm. the car got 16 mpg on the way to carlisle and hopefully will get a little better then that now that i put a better suited carb on it. so it really depends what you consider a cruiser.
