Royce, if you ever need one of these or the STREET BOSS, let me know. The fellow that has them cast is a friend of mine. He sells them through Bush performance in Ft. Smith. They also do all of the head modifications. Some company in Tulsa casts them, but Gary did the design and has the patent.
There is to my way of thinking no good reason to spend a lot of time and money making a 351 Windsor slower by putting a set of Cleveland heads on top. There are Windsor heads on the market that will outflow and outperform the Cleveland heads of twenty and thirty years ago. Technology is a good thing! I can't fault someone for wanting something different, that's why all my stuff is FE powered. I could easily make more power cheaper with a windsor motor. But FE's are where my interest lies.
If he's running that good it's because he has put alot of time and money into the engine and its development.
At my local strip the fastest car every Saturday is usually an old big block Chevy front motored rail that runs 7.80's on gasoline. The second fastest car is a Fox Bodied Mustang with a 331 CI 302 Ford, windsor headed that runs 8.01's. He is running a single four barrel too. His name is Gary Rohe, the car has been national NMCA champ a couple times and has passed numerous teardowns. Scary Fast!
I just wish I could afford to make one of my FE's run as good as Jackie Tarner's 390 powered Falcon. It ran 10.90's last year with the single 4V Edelbrock Performer RPM intake in the 3300 pound '64 Falcon with a C6. All it takes is cash!
