Re: motor swap!
thats a pretty loaded question. Speaking for me personally, length of time depends on who and what I'm doing it for.
If I'm doing it for myself or even someone else and its just going to be a daily driver or sold, I wont cut any corners but I'm not going to go crazy cleaning things up and replacing things just because they are dirty or rusty.
Now on the other hand, if its something I'm looking to keep and/or make better than factory, I'll spend some time redoing (paint, wiring, gaskets, etc.) everything to make it perfect, in which case it could take years as stated earlier :lol:
