Robert said: <<Well, Have you checked out any T1 engines and the horsepower they make when they are built right?? 150+HP and they are street machines. If careful attention to known weak spots, and then strengthen them, a reliable engine with a power increase can be done and it live a long life. Gene Berg has increased HP engines live well past 100,000 miles.>> However on Gene Berg Enterprises Web site at www.geneberg.com I found the following: "The more we tested, the more apparent it became that too high of a CR is the major source of the heat in the heads that causes failures. We found the volumetric efficiency of the engine is also another large factor to life and power. When all parts and CR are correctly matched to the engine, so the volume of proper octane fuel and air is what the engine requires, the engine runs cooler, makes more power and lasts longer than the stock engine did. For long life, we recommend conservative compression ratios, especially since pump gasoline quality has deteriorated so badly. GB 801-CR is mandatory reading. We lowered the compression of our own 78 x 88-bus engine from 8.5:1 to 6.9:1. We leaned the Berg 42 special carbs two jet sizes, advanced the timing 4 extra degrees and got better performance. The engine ran over 50 degrees cooler, with 3-MPG improvement in economy. This engine had over 187,000 miles on it when sold and is still running years later. Be clear that head/guide maintenance must be carried out at regular intervals as prescribed in our copyrighted instructions that come with our heads to prevent a valve from breaking."
