Re: cooling my 406
It was mentioned above, you will need the head steam holes to keep the coolant from boiling. As south as you are, no anti freeze is needed, use an alloy radiator, water wetter, electric fan mounted behind the rad and you will be fine.Even the best fan blade will cost you 20 H.P., I've always used a 160 degree stat with a few small holes drilled in it,no problem in the summer.
I drag raced a 415'' with pro action heads and no steam holes, and no problems, big power.I just picked up a new radiator from speedway for a 'chevelle, $140.
