Torn between 360/408 and 440

Car will be mainly cruising through mountains and side roads. Maybe go to the strip a few times a year just to see what it will run.

if thats all you are doing with it i'd go a very mild 360 with a 2.94 or 3.23 gear and be done with it..

that being said, there is nothing like a big block abody. they are awesome.. but for your intended use i'd go with what i posted above..
