Why the /6

Got so lucky and found a '75 slant engine on CL for $100. The '75 has the peanut plugs and hardened seats, but still had the forged crank. Exactly what I wanted! Got my 1.70/1.44 valves. Now trying to figure out how to retrofit my B&M blower to it!

I got slant sickness! Somebody stop me!
