NOTES<br />
For the best performance, an S&S carburetor, performance<br />
cams, and performance exhaust are recommended.<br />
Do to the increased displacement and compression, cams<br />
with longer duration are recommended for easier starting.<br />
If replacing the pistons in a older 77" stroker engine, stroker<br />
plates are required, and all clearances must be checked.<br />
S&S offers machine shop services through the S&S Service<br />
and Speed Center. New pistons can be fit to your existing<br />
cylinders for a reasonable charge. See Section 10: Dealer<br />
Services, page 10-6.<br />
