LOL.. The old motor wouldn't pull the car along in 3rd gear it was so wore out, and 2nd gear would lose power on a 1% grade. I'm also thinking that since the engine was bored out .80 over, it will have thinner cyl walls and not as much iron to work as a heat sink.. I'm going to try dropping the coolant to 20/80 (was 50/50 as i drove it all winter in below zero conditions at times) and see if the 'thinner' mix works better for summer.. Worse case is that I'll have the radiator rebuilt.. Have rebuilt just about everything else on the old girl
