Ken,
Had to run up to Oregon to do Hepa filter certification for the VA
Hospital and at the same time exchange RandyGrubb's BLASTOLENE final
ratio from the 3.70 to a 3.55 as his Super Coach is only 6-7K lbs in
weight.
I have few more things to do before I fire up the 540.
Believe it or not, I'm planning to leave next Wed evening.
One way or another, I will be there in Shawnee.
I have Rob Muller and John Sharp standing by to pick me up at Houston
Airport and Dan Gregg at Oklahoma city just in case I have failer.
Frank Jenkins will be smiling like Possum eating S--T should I not
pull in with my coach. Now, I would have little more sympathy and not
do the Possum thing.
I learned that expression during my 5 years at OU in Norman, also
learned a lot about football to.
Hope you fix that weak ignition.
