Designed and manufactured by Cleveland enthusiast and Mechanical Engineer Mark McKeown, the Titus Performance Aftermarket Cleveland Block is the largest cubic inch capacity Small Block Ford - bar none!

The 'New Classic' takes the 351 Cleveland to the next level. With the best of both worlds, the redesigned block maximizes power potential – ideal for street-rods, high-end sports cars, drag racers, muscle cars, amateur and pro racers, classic cars, boats.  You name it, a Titus can do it.


Our goal is to manufacture and distribute any part needed for a Cleveland build. Whether we make them or not, the products we sell are are tried and true–tested to endure top quality. 

We know how to get proven results with a countless number of combinations and will always recommend the parts and components for your build.

Just like a strong block is the foundation for any strong engine, so is John 3:16 for the foundation of our faith.

"​For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life."
