roller cam or flat tappet?

With a degree wheel and some measuring equipment you could map out the cam and determine lift and such. But it probably is only worth doing if you want to try and sell it. Get the cam you need for your setup. To my uneducated eye, that looks like a FT cam and more mild than wild. Just a guess.
thanks buddy. i will look into a new one this week. and get it ordered. along with rocker arms too
