- Compression ratios listed are approximate and are calculated using the correct length cylinders as specified by S&S
- Requires the use of connecting rods with a rod length of 7.440"; Use of earlier connecting rods with a rod length of 7.470" will result in a slight increase in the compression ratio of about 1/2 point, and may also result in clearance problems (check all piston to cylinder head clearances carefully when using the early style rods).
