I just picked up a 1966 520 for $200. The body is in great shape. No rust, dents and just minor scratches. The interior is also in good shape. The reason for the low price is no motor. Now I know the 66 520 is semi rare and so is the 1300cc motor that came in it (J13). So from looking around it seems to be the easiest route to get this on the road again is to find a j13 or a j15 as those will just bolt back in. Here is where my dilemma begins. The truck came with a spare 1600cc motor from the datsun roadster (R16). I don't have the tranny for this motor either. What do you guys consider the best option for this rebuild? I am not against trying something new, but I also kinda want to get it going as soon as I can. Performance/speed is all good, but not the most of my worries. I'm more so looking for the route that would allow me to find parts easily and install without too much modification (an oxymoron on I know!). In the end I'd just like a good reliable daily driver. I will post some pics this weekend as the truck is now in my dads shop.
