I was wondering what would be a good street manifold for a 5.0...I was looking at the Comp Cams upper intake...I've heard the box type manifold hurts your low end, but they promise 20hp with no loss of low end...You know how promises go though...lol. I was also checking out the pro.products manifold...My car has header back exhaust w/ no cats...The lower geared ford racing manual opcorn:tranny & 3.73s, MSD 6AL Ignition box & system...Also an intake...It's been rebuilt and I'm not sure if it's been bored or not...It has a stock cam also...I'm looking to go with a manifold I can bolt on now and then upgrade my cam later with nothing no more radical than an F303 cam or the Comp Cam I'm thinking about getting with the following specs...1,600-5,600 rpm...Duration Int.216 Ex.224 and Lift Intake .544" and Exhaust .555"
