Indeed, the GM and Ford small-block pushrod V8s are typically torquey
beasts, and they deliver gobs of it over a wide range of RPMs. The
chain-driven pushrod valvetrains generally aren't designed for high
RPMs, but within their limits, they do provide very reliable service,
usually without need for periodic valve lash adjustment. I love the
likes of aluminum Honda DOHC engines, but this is more complex
machinery, it needs more maintenance to perform it's best, and the one I
had produced most of it's torque at higher RPMs, and a much narrower
range at that--it'd be a terrible engine for off-roading, I think!
