Guys, a stock 302 from ford mustang runs 1 1/2 inch headers. Add 40% more cubes, more compression, and better heads. Now, 1 1/2 inch headers defeats the purpose, its like putting a 300 cfm 2 barrel on a 427 motor. 427 ci motors in 2400 pound cars don't lack for low end power even if you run 2 1/8 inch headers. Its the cobination that makes the motor go. Scott
