Anyone know of any place to easily pick up 5-10 gallons of unleaded race gas in Phoenix? Preferably on the northwest side of town. I want to run some through the car before Saturdays meet at Speedworld. The car has too much timing in itr right now. Pinging pretty good in 2nd gear when it's to the floor. Can't get back to the shop before Saturday to dial it down, so I'll try some good fuel.
