First of all I apologize if this has been talked about. After an hour of searching I thought I was would just post it. I was browsing http://www.broncohio.com/tech/ebvins.html and for 1966 only they have the two availible engines listed as 170 and 240? Is this just a typo? I have seriously considered swapping a 240/300 in to replace the tired 170. But it sounds like several have tried with lots of effort and regret.
