I REBUILT my Cleveland 351 V8 to run on LPG, but I'm considering going back to petrol. Do I need to replace the anti-pollution equipment? Can I run it on ULP?
BY LAW, you must run the pollution equipment the car was built with, so refit whatever equipment it had when it left the factory. You can run it on unleaded, provided you have hardened valve seat inserts or add valve seat lubricant to reduce valve seat wear.
