So I want to get a fresh block and rebuild a 2270 street engine. I have always loved the look of horizontal fans and would really like to integrate this into the build.

I have seen a few, (even an electric one) but which would be recommended? Would it be worth looking into building a 90 degree coupling? (or would it be too power sapping) - I have access to lots of billet and machinery, so If anyone has done such a thing I would be very interested to see what you have done.

Anybody running a HF in a Fourteener? Would love to see pics if so.

Thanks in advance.

I think the sprung tensioner you were referring to is this one:
http://www.corvair.com/user-cgi/catalog.cg...AIN&page=15

They were never stock and this one is $109.

As for the fan, notice that mine has practically vertical fins. This was a change in 65 as the older fans, more like the squirrel cage, supposedly cooled too much. I find it interesting that a 2.7L 6cyl engine only needed a vertically bladed fan to keep it cool.

Didn't the 2.7's have cooling issues? (IMG:style_emoticons/default/wink.gif)

Yeah, I know, self-inflicted... Porsche intentionally made the engines run hot (5 blade fan) in order to make the thermal reactor work.

Let me clarify, all corvair engines were 2.7L from 65-69 no matter the HP. They changed number of carbs, size of valves, but the displacement stayed the same. The fan you see on my engine was what they also switched to. It has fan blades with no discernible pitch to them. Before this the fans had blades like our squirrel cages.
