The carbs are kinda blubbery @ 4 lbs and wake right up with a few more lbs so my thought was if W/M does as they claim I would be able to run 6 or 7 lbs with pump gas on the street without worry.I have melted a few pistons!

Al........a 9 second car shouldn't be melting pistons. How much timing were you running when those pistons were in the motor?


I personally don't think he melted pistons, those pistons were damaged by pre ignition. In other words not good enough gas was used. I bet the rod bearing was beat up on that cylinder. IMO
