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.

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.

Fans of the Cleveland engine now have an aftermarket block based on their engine's platform but with many improvements. The Titus block from MME looks to deliver many of the features available previously to only Windsor block users.
