Good job Wifey, Not really all that hardWifey said:Bore = 4.03
Stroke= 3.96
Bore +.030 = 4.06
Radius = 2.03
Radius x Radius = 4.1209 x 3.14 =12.9396 x (stroke) 3.96 =51.2409 x 10(cyl.)
= 512.40 cu.in. Close as i can get with a non scientific calculator
The 522's are usually stroked or had custom sleeves made.
