I have just finished ordering all my engine upgrades for now. The list includes: dual-out pacemaker header package from fordsix, 2 flowmaster super 40 series mufflers, h/w carb from stovebolt with stovebolt adapter and linkage, a new High Energy 252H cam from comp cams, a dual roller timing chain from fordsix. I am pretty sure that is all of it for now. I hope this produces some more fun for me in the car. I have a '66 mustang with a '68 200, the engine has been in the car for about 6 or 7 years. It's in alright shape. Any suggestions on installing some of these parts would be helpful.
