Mike, and as you know, 3500rpm is nothing for a small block Chev. Smart move though to "go easy" on it. Still, foot to the floor, it "could" have done the hill faster. But what's the hurry....is it a race ? Not really.
230 degrees, yes, for many years GM has decided that "running them warm" is routine. Even back in the 80's, they like to run their car engines at 210 or so in everyday use. Likely to get cleaner emissions and better economy.
Nissan on the other hand, still likes to run them below 200. My Frontier runs at 193 to 198, towing or not. (as reported by the scangage, which is always the truck )
They all work and last a long time.
The six speed GM trucks have a little bit of an advantage over the four speeds for towing.
Yup no race for me... I was a long way from home...Why beat it... I dont take it much over 3500-4000. 1st gear is low on the chevys. I was barely 1/4 throttle. I never have my foot in the floor. I just let it work.
But 1st to second is a 41% difference the 4L60 trans needs to overcome. so second is a long long long pull graduating RPM's up to 3rd.
Temps run 190f on chevys not towing... Every chevy I have had the t stats were 190f's
