Xfbodyx, I built my 77 360 back in the early to mid 90s.... it's .030 over with 9.5:1 compression, designed to run on basically ExxonMobil 93 octane.... it's basically a 340 but with the bigger main crank journal in a360.... still running 1.88/1.60 valves (don't ask lol) but with the heads fully ported and polished to 80% of the values... yes I need a bigger cam but..............
I drove it all the time and even drove it on a 200 mile each way trip and it has never overheated....
I did however, after lots of research, took it to a machine shop for total prep before I built it.... the machine shop built promod engines, and overall bad ass engines .....
I did install ARP rod bolts in the resized oe rods......
