Comp cams xe268h for 318

It's not a bad cam............. with a 2800TC, and at least 3.55s
But with an 1800TC the rpm is slow enough to keep the intake in reversion, bleeding cylinder pressure back into the intake, making it sound like a top-fueler, while making the engine gutless............. and the 2.76 gears keep it in the gutless zone until near 25/30 mph.
And when it finally starts building pressure, it is still just a 204/214/112 cam. Just about 1.5 sizes bigger than stock. You'd be better off with a good used factory 360 2bbl cam. IIRC those were 252/256/112, and can be installed at ICA of 56 to 59*, right on target; and that cam will make great fuel mileage.
