Gives a slant 6 a run for the money

Interchangeability between years is also very good. Had a 81 Volvo gas engine, 5 speed standard,body rusted badly. Purchased 86 Wagon, good body, but had the diesel with an auto. Of course, previous owner did not do the timing belt on the diesel, so motor ad damage, Within two days had both drive trains out and gas engine with 5 speed in the newer non rusty wagon. All nut plates etc where on both vehicles, so clutch cable hole, fuel tanks,motor mounts, radiators, air cleaners, dropped right in. 5 years between them, also the 4 cyl block bolt patterns are the same, heard a guy put a mid 80's Volvo turbo 4 cylinder into a older Volvo 544 ( looks like a 40's Ford) , supposedly a easy install.
