I bought a complete running Chev 355 that was built for drag racing and raced for 1 year. I want to use it for a 69 Camaro im going to buy. The motor is 13.1 compression. Are there octane modifires or boostres that can be added to 93 oct fuel that my motor can run on. I plan to buy a good set of aluminum heads. Im dont want to buy $8.00 per gallon gas for 110. I know I can swap to E-85 but I want to do that as a lats resort. Are there other options? I dont plan to race the car. Just street drive. Thanks in advance.
