Overheating 360 new engine

I bet I could make 5 pretty simple changes and you’d make more power and it would run better at 160.

An 8% grade is pretty effing steep. I say EGT’s should be MANDATORY in cars so you can watch the exhaust temperature as the car is driven. That’s why God made the transmission. Sometimes you have to downshift.
Yeah that's 8 feet of rise in 100 feet. 8 miles of rise in 100 miles. That's a HUGE grade. I'm a model railroader so I know grades. lol
