Yeah, they're kinda pricey, the lifters are even more pricey.

Duration is kinda low, but that could be due to the 108 LSA. Other than that, sounds GOOD to me! But with those numbers, the car is gonna "sound" like azz until about 3,000 RPM!

Only caution I'm gonna give you on a solid cam. Learn the RIGHT way to set valve lash, get used to it, get good at it, do it often!!!

And you'll have NOOOOOO problems with it!

Thanks for that info, the cam part #31-335-4 COMP CAMS Iam concerned about piston to valve clearance, Here are the pistons that iam useing, 6.5cc/Flat Top
Effective Head Volume: 6.5cc. with my 60 cc Edelbrock RPM HEADS Its going to be 10.5.1 Comp. With that cam do you think i will have any Piston to valve clearance? I would hate to have to buy it put it in cgeck it and send it back, Thanks CAR9FAN

You are aware that the cam you have listed has the old 302 firing order in it, right? Any comp cam with the prefix #31 has this firing order. Just in case, the old firing order is 1-5-4-2-6-3-7-8. The H.O. firing order is 1-3-7-2-6-5-4-8. Any comp cam with the prefix #35 has this firing order.

Your cam

I don't think you will have trouble with clearance. What size valves? 2.02/1.60?
