[Robert_5_liter]

I have stock ported heads but i see they are not good and i need better ones it is a 5-speed car andthe 1.999 60 ft was done on goodyear regular street tires with the stock intake on the car last week launching at 1400 rpm. but on my scanmaster it shows the computer pulling the timing back to 27 degrees and a ford tech said the computer is designed to pull timing through the massair readings and somebody on this site should be able to help me with that . my buddies 95 cobra wont pull over 5K and shows timing at 29 degrees I think pro m makes something for this and brothers has it in their catalog but i dont have one here to read thanks for the help guys.
