I recently purchased my '52 truck and am trying to research all I can about the motor that is in the truck. It is an in-line 6 cylinder. It is not the flathead 'Super Hurricane', I don't think. This motor has a single valve cover and the word 'Hurricane' cast into the head. I have done some online research and I believe that the motor is an F-head. 161 cubic inch. I am away from the truck right now so I cannot post a picture but the reading I have done does not suggest that this was a motor that was even offered in those Willy's trucks. Is this correct? I am seriously considering an engine swap and would like to know the specs on this F-head in-line 6 cylinder [weight, length, height etc]. Thanks.
