Sam  wanted to know where to buy one. Not sure, I googled and its not clear 
to me.  Maybe one of the suppliers on the list has them, (your best bet). 
Mark D? Ron  S? Jim T? Any other vendors on the list? What cha got?

Also I noted on  the google search, the 356 pulleys don't have a bushing. 
Buy a mounting  bushing, be sure it has the threaded end to fit your nut. I 
happened to have  an aftermarket VW pulley where the bushing was not welded 
into the rear half  of the pulley. Took it apart and the bushing fit 
perfectly into the 356 parts.  Don't forget the shim washers.

Good point Clara,
Since I have CHT and I can  also monitor oil temp. I can keep an eye on 
that.

BTW, I will  have to do a few more runs swapping the pulleys to get the oil 
temp  difference.

The Porsche pulley is smaller, which mean the fan runs faster and blows  
more air.

At hot weather this could be good.    But not when it is cold.
don't get rid of the stock pulley  and belt.  
When the weather cools down in the  fall you will want to change back, or 
the engine can be damaged by running too  cold.

So you are saying that with the fan  running a little slower ? the engine 
ran cooler ?

Is  this a fan load/resistance issue ?
