so i've decided to scrap the plans to rebuild my 2.3 16v engine, it's just not smart money at $6-8k, so im looking to do a swap of a M104 and i'm trying to price it out, i'd ideally like to get my hands on a 3.6..but a 3.4 will work just as well if nothing else then i'll get a 3.2. aside from junkyards searches, does anyone have any good sources for good used engines? my google search is not as lucrative as i'd like. most places want one specific car to search for..not a range of cars
