My future cobra will be mostly used on the street but occasionally at the track. I'm heavily considering a JBL. No, I'm not planning on using the Dart block or a Windsor with Cleveland heads. In 1985, Joe Fontana designed and built a "real" Clevor engine block out of aluminum having the best attributes of the Windsor and Cleveland as I stated in my earlier message. Clevors are still being manufactured today. It's surprising how many people have never heard of them giving their performance characteristics. The engines are typically found in sprint cars, track cars, and Panteras. They are designed for up to 1,500HP...like the Shelby 427 block. Fontana Automotive has a real nice brochure on their Clevor blocks. Call Joe and he will send you one. They are located in Gardena, CA.
