For sake of interest (if any)

D = bore x bore x stroke x #cyl x pi /4

or

D = bore x bore x stroke x #cyl x .785   ...also gets you there about as 
close.

thus, 3.438 \2 = 11.8198 x 2.94 = 34.75 x 6 = 208.5 x 3.1416 = 655/4 = 
163.7559


3.498 \2  etc etc etc = 169.5231 ci if you wanna nitpick and squeak it 
down to the Nth degree.   Call it about 170 ci.  or thereabouts.   You 
oick up almost 6 cubes.

Providing the engine is tweaked and is making around 1 hp/inch\2 that 
would add about 5 hp.   Not really worth the money to go to the trouble 
if power was the only reason for boring .060.  Easier and cheaper to 
whittle some of the fan for 5 hp.

Or, you could go to a K&N air filter ahead of it all and pick up an 
extra 5 hp AND let Nature bore your cylinders for you all at the same 
time.  :)


Please excuse my ad-hoc math function representations before some large 
brane sort points out that I'm using the wrong symbols.

Isn't math annoying?
