Hello from Iceland
I have a 911 motor from 1973 911T I have taken apart. My proplem is I am not sure what motor I have after I have mesured the cylender and head.
the head has the number 911.104.302.0R on it .
The ports messure is Int:29 mm Ex 33mm
The cylender bore is is 90 mm and KS854/2A writen on it
I have here the book: How to rebuild and modify Porshe 911 engines 1965-1989
And I can not find motor with that bore and then that head in that book.
It does not mach up with the model year or the port size
Can someone help me clear this for me.
