"Solid" seems like such an inadequate word when describing the Volvo 200 and 700 series cars, but even the turbocharged factory engines have a tough time grunting out the torque needed to haul all that Swedish steel with the proper quickness, especially when you're towing your bass boat. Swapping a good ol' Detroit pushrod V8 into a Volvo has long been a popular swap; so popular, in fact, that a couple of companies sell everything you need to make the job a near-bolt-in deal. You want a small-block Chevy? Talk to the folks at Jaguars That Run and they'll hook you up. If you like the smaller size and lighter weight of the Ford 5.0, Converse Engineering has a very sanitary (and Thor-approved) kit for you.
