This is not a stang, but it has a 600cfm edelbrock carb. and a manual pump. I have measured the FP, but I want to see what some of you think it should be. The motor is pinging, I am thinking low FP may be the cause. It has gotten gradually worse, and no work was done to the car. The car is not down on power and not running hot. The plugs are bosch platinum+4 and they are red in color, WTF is that? They looked normal 2 wks ago, but he has been running octane boost. Its in an 86 monte, mild 305 combo. Nice car, I drove it today. It needs some gears.
