I dont see a problem. So is it 160 or 180? Is the W/pump Fan still on the car?

I think if you are running an aluminum rad than you can use a 180 stat. Might need more cfm from fans. what type of water pump are you running. If you are running and E intake make sure the holes on the water cross over that bolts to the head are gasket size. I have a 4 gen fans 160 stat 4 core brass copper rad aluminum w/p divider cleareanced holes opened on the intake and my 406 runs 180 degrees. So I think yous will run cool too.

I know we've covered this, but i dont recall a clear answer. Can you run too cold (within reason)? I had the 428 running at 165. How cold is too cold?

Hopefully the 462 is the same way.

It needs to get warm enough to evaperate moisture out of the valve covers and crankcase. No thermostat or un-restricted systems wont alow the radiator sufficient time to do its job as a heat exchanger.

Cort I think a engine that runs between 180-200 is a warm enough temp to do what B and P is talking about.

So 170ish should likely be fine if you're doing longer drives and not a lot of quick runs where the car never warms up, i would guess.

Blowflyg, we need some feedback. I think your question is, how much more heat is produced by adding 61 cid? I would guess 10 %
