More Spica stuff

Who said he had just one profiled cam?  Wes is the type of person to spend
the time it takes to design cams for various applications.  It is certainly
no mean feat to do that, and make the car pass emissions.

I thought they already had equal length tubes!

I really don't think so, Wes wouldn't settle for that.  He uses his
Dynograph LED richness indicators to help straighten all that out.

Yow, sounds very initimidating.  Actually Wes is selling and configuring
Electromotive's EFI as well.  He did a Maser V6 twin turbo with it, and it
is the way of the future for hot rods.  He controls all aspects of the fuel
and ignition curve with a laptop.  I certainly don't think you could adapt
Spica for that, however.

Obviously I'm a fan of Wes, he's the person I go to for all of Turner's
problems, and I'm just completely satisfied with his values and abilities.
He's been working with fuel injection and complete race car prep since the
mid-60's, but will listen to anyone's ideas and give them due consideration.
