what is the best small block and why ?
Walk? What did you use for main bolts/caps?
Ask the factory , both were factory fresh engines that lasted under 10,000 miles .
I f you start out with a 1971 down 340 or any year 360 , non magnum which is the better starting point ? 340 better crank , better intake , better cam , timing chain /gears , better piston and rods and heads . Just rebuild with better cam will smoke the 360 or 318 , unless you change a lot of the parts on the 360-318 , intake , pistons crank , heads .
Or am I missing something .
