<DIV>Bill, if a good strong sport engine is what you want, the OS160 is the
ticket. With a perry pump and either a Hatori header or a Mueller RTC, and a
cheapie" Macs pipe, you will have a very good, reliable, pattern type set-up.
Relatively inexpensive with only about a 4-5 ounce "penalty" compared to the
full blown pattern set-ups. As easy to adjust as the MOKI is.</DIV>

low noise, durability (2C), and<BR>>reliability (2C), I think they are
doing pretty good.<BR>><BR>>Dave</FONT></BLOCKQUOTE></DIV>
