A lot of data here, Thanks.
3800 miles on a rebuild, tanked and cleaned. Mild Isky cam & mild shaved heads. using all new high quality 12v gauges, elect fan that covers the full size of the radiator. I am going to start with high flow thermostats, up-graded water pumps. larger expansion tank and dump the 4lb radiator cap and start with a 7lb then a 10lb. see if that helps. keeping the alum rad for now and see if that helps. Before I invest $$$$ in a brass radiator. I'll keep ya posted, It will be a while till I can get to it.
