Default E85 effects on operating temps

Hi all,
I ran my motor up today and it took for ever to come up to some sort of operating temp. I let it idle for about 7-10 mins with a couple of revs using about 10l of fuel. The temp got up to 75'C.
Now while this sounds like I am complaining about it, I'm not, just wanting to know if its ok.
Engine is an all alloy 555cui running 12.7:1 compression, tunnel ram with 2x840cfm pro-systems carburettors. Running on the rich side which could also contribute? The runners of the tunnel ram condensate up quite a bits too.
Any thoughts or could anyone lead me somewhere I could get some answers.
My major concerns with this street/strip motor was over-heating and if I don't have to worry about it, that's great. I have plenty of experience with methanol, but was unsure of the cooling capabilities of E85.
Cheers

E85 burns cooler than normal unleaded, that is probably why.

Yeah, I knew it would run cooler, but not that cool. Sorry Damo, I should have written my original post like this to include the bold text.
Cheers
