I got a bunch of buddies with front engine dragsters and some door cars that are all injected alky.All the door cars have blocks filled with water/water wetter(just for corosoin),but no pumps or radiators.Charlie's roadster has a flathead,blown injected alky,he runs and entire cooling system.Found it (flatty)wouldn't live without it.But the guys in the rails all run their blocks DRY.If you break something and then drive thru 200 degree water,it sucks!!They pull all the freeze plugs,thermostat housings,manifold plugs.... leave everything open.Noone has had any problems with it ...yet.Don't sound right to me.Just passing along what I've seen
