Thanks. I'm really liking those taller tires upfront.

With the ambient temps around 65 today I took the GMC out for a nice back road cruise. I'd say the avg speed was 45 with some slower and some higher speeds and a couple stop sign stops.The entire route is approx 60 stress relieving miles. The cooling fan did not come on once during this cruise.
The temps avg'ed 170-180, never getting above 185. Since I don't have a heater yet I'd say this isn't high enough to provide adequate heat in the upcoming colder days so I may up the thermostat to a 180. On the front burner is deciding how to heat the GMC. I may move the Chevy's Arvin recirc over to the Jimmy while I do it's engine swap. I dunno, still ciphering this one out as the Arvins blower motor is still 6V. Course the Chevy will become 12v on the engine swap so I'm going to have to deal with it anyways LOL. It's always something.....
Man, it was a VERY relaxing cruise, that 350 SBC has a nice low rumble at 1500 rpm.....
