Pully Question
 

Guys:

Need some help.
My engine is buried in storage and I'm about to buy a second hand trigger wheel/Crank pulley kit for dual plug ignition I plan to buy down the road. I'm buying packaged with set of ported heads drilled for dual plug.
I want to make sure it is same diameter as my current pulley. Would take me 1/2 day with fork truck to get my engine out of storage at our warehouse.
Does anyone know what my stock pulley size is?
And actually, Does anyone know if it is is not correct DIA, if I would have any interference or clearence issues by going larger or smaller and if there are varrying fan pulley sizes available to correct the ratio? (if not, I can machine my own)

My Engine:
69 2,0 E MFI

Thanks for the help,http://forums.pelicanparts.com/uploa...1093476465.jpg

From 1969 to 1975, the pulley was 116mm (911.102.017.50). It then went to 131mm wich just makes the fan spin faster. Either size will work.

Where'd you find that pulley?

Hi John:
Was buying a set of ported twin plug heads from a classified on 914club. The guy had this trigger kit as well so I bought both.

Clewett Engineering sells them.
