Engine of the Day: Volvo Red BlockS

Even though I just replaced a perfectly good Volvo B23 engine with a Ford 302, that doesn't mean I lack appreciation for the tough and versatile OHC slant-four Volvo engine family, which powered the majority of Volvo cars from the late 70s through the late 90s. Available with 8 valves or 16, naturally aspirated or turbocharged, the Red Block was the direct descendant of the early-60s-vintage pushrod B18. [Wikipedia]
