Let me understand the logic here. Your spending $2500 for cams and at least $1500-2000 in labor, tuning and dyno time to get everything dialed in for 20-25whp at best. You can find a used ESS 535 kit for 5-6k and install yourself in less than 8 hours and gain 100whp. I might add ESS has had zero failures on all their kits! Need we discuss this any further....
