I currently have a Lexus SC300 5speed with a 1JZGTE swap that I've been having mechanical issues with for a while. I'm not mechanically inclined enough to know how to fix them and I think it's time to give up on it. I placed it on craigslist and got a reply from a guy with a 1974 260Z that I'm pretty much in love with. The body isn't perfect but I wouldn't expect it to be on an unrestored Datsun so that's no big deal. Another up side is that it has a claimed 59,000 miles on it. However at some point someone swapped in a carbed L28 and apparently even though it runs at the moment, it smokes at high RPMs and the owner feels it will need a rebuild soon. I've always adored the Datsun Z since I was a kid watching Transformers and to be honest it's my dream car, I simply lack any perspective when it comes to getting it because I'm skewed by my daydreams. I'm not aware of where to get a new engine or even a decently priced rebuild kit for it so I came to the experts hoping for some advice as to whether this is a good deal or if I'd be an idiot for making the trade. I know due to rarity that my car has some value and the swap was done well by pros, I've just run out of money and am chasing gremlins. Any at all would be appreciated it
