This isn't a perfect museum piece Volvo, but the asking price is favorable and most of the hard work has already been done. Anyone looking to shove a Ford V8 into the front of a Volvo 240 will need to source a kit from Converse Engineering (or Jagsthatrun) and they aren't cheap. Even if you get a free Volvo and free 5.0 V8, the total cost of the conversion can easily exceed the asking price on today's feature.
Ford's 5.0 liter (302 cubic inch) V8 is rating somewhere in the low 200 horsepower range from the factory (depending on donor vehicle), but aftermarket parts are available that will easily boost the power into the 300 hp range. This one could probably use some high compression internals...but that would be after you swap in a T-5 manual to replace the AOD slushbox.
