After getting our Windsor baseline, we installed the Cleveland heads on our 347 short-block.

We spun up the Clevor hybrid on the engine dyno to see if Cleveland heads still reign supreme.

Cleveland heads have always had an advantage over Windsor heads from the factory.

We find out, does that still hold true with today's aftermarket?

Back in the day, the Clevor engine was the hot ticket for OEM Blue-Oval performance.

This build proves it's still wirthwhile today, especially with aftermarket components.

You can't go wrong with building a classic Ford Model A.

John Hilderbrand's 1931 Model A is one rad ride.

In another vintage Blue Oval vs Bowtie dyno showdown, a pair of 1969-spec 302 engines are pitted against one another.

With the same bore and stroke, they took two different approaches to the same problem.
