Back when I was running V8 Pontiacs, I could get about 5 tenths out of methanol compared to 93 octane gas and that was just changing fuel. I didn't change anything on the motor other then the carburater. Biggest problem was keeping the engine warn in cooler weather! I did change the thermostat to a 195*. I had to change oil more often due to condensation in the block, I could drain off a cup of water a week if it was damp out when racing. Also, if you keep the fuel lines and carb full, you don't need to drain the system. We raced once a week and sometimes twice a week so I didn't have any problems with drying out lines. Each winter I would replace regulators diaprams, pump diaprams, filters, and some hose. I figured with gas I would have to do about the same anyway. Joe H
