I think I need to just ignore 5th altogether when running around in the 80-90mph Houston madness. I have heard that its a $1000 to swap the .64 for the .82, definitely not worth it, I'd change the rear ratio first.
I do like the way that torquey 294S cam takes over at 2k/70 mph mark and just pulls and pulls and pulls. And by the way, I pounded the absolute snot out of it today for 200 miles with the final timing and carb settings you and I discussed and with that new fan, it never got over 90*C water and 105*C
oil. Runs great.
