content: I found this book to be very informative and easy to understand. I had been looking for sometime, for any information reguarding the chevrolet inline six cylinders, 250 and 292. It really help me with the knowledge and unstanding of this inline six cylinder motor, that i find to be very inpressive and highly underated by most small block V-8 chevy motor heads. I just wish I could have found this book long before I finished building my motor. But that's ok, I already have plans for the next motor and I will be refering to this book when building torque and horsepower.
