I just put another 40 miles on a combination of highway and street. I drove to the local town went to the self serve car wash, did a minor retune of the carb, lowered the idle down to 900 rpm and I also richened the idle mixture slightly.This engine is just as smooth or maybe smoother than the old setup. Down the highway it is great you could drive it 65 to 80 mph all day. Around town its a different story..still pretty smooth but without tailpipes this engine just booms and must shake every window.
As far as engine oil temps with the hardblok shortblock, I really don't see any issues, down the highway the oil temp reads 190 degrees. My thermostat is a 160 so that is right in line with what I have read about oil temps being 30 degrees warmer then coolant temps. In town it creeps up to 210..which still isn't an issue. I'm assuming less volume being pump at lower rpms causes the increase. From what I have read I shouldn't have any issues unless I'm seeing 250 plus for extended periods.
