3M Engines

[wgalligan]

Jerry,

Get with Karl Mueller.  He has been making headers for us for the O.S. 14.0
and they will also fit right on to the 3m  1.40 and 1.70.  we have.
Seems everything about this 3M is nearly compatible with the O.S.   OR use
any other brand that would fit the O.S. would be fine too.  I have found
Karls headers to be of exceptional quality and durability.
What a beautifull weekend here in Texas.   Todd Blose has been putting on
his annual contest and 38 pilots have shown up.  Large group in advanced and
masters this year in districy 6.

Well back off to the contest....

Wayne
