I will catch flack but here goes, Flathead Ford V8s are cool and nostalgic but not very powerful or sturdy. The connecting rods are long and break easily when leaned on. Valves are shrouded and don't flow good unless you spend a lot of time and/or money to relieve them. They have cooling issues and oiling problems. All that said, a clean Model A with a multi carb flathead will always make you smile.
