Steve,
It's great to hear you've rebuilt the original numbers matching engine
and trans. It's also great to hear about the race engine and
transmission. I'll be traveling to SSCC in a few weeks and don't know
how that lines up with the SOVREN race coming up, but if it doesn't
interfere with that weekend, and if I've got the time, Sam and I might
be able to make it. Keep us informed on the where and when. :) Sam
turned 15 this summer and he's already doing a little driving around the
property.
Thanks,
Asa Jay
