I took a Dove cast aluminum overflow tank and modified it to fit a small block. I wanted to match the look of my valve covers and air filter which are also cast aluminum, plus I didn't want to get into the headache of the leaks associated (rightly or wrongly) with the brass units.

We cut the bottom off of the casting, (that was a gut-check!) and machined a new thermostat cover out of a piece of aluminum and welded the whole thing back up.

The Dove tank is pretty pricey; guessing $375+ and I'm not sure what a local machine shop would charge you to do the new thermostat cover, but I think I still have the print at home and would be happy to send it to you.

I'm very pleased with the result, other than having the occasional onlooker yapping at me that I'm trying to fool them into thinking I have a big block... there is a picture of the new bottom on the tank in my gallery.

Actually, I was thinking of doing another one for my 66 Mustang, but common sense keeps getting in the way.
