This is a cam that i found spec r Duration is 216/224 RPM range is 1500 to 6000 will this work on a 4.8 with 918 springs

 

yes it will work but i dont know how good.

 

it will work but you are going to have to do some good tuning on it. whats the LSA?

 

I think the LSA is 112 or a 114

 

What is the differents from a 112 LSA AND 114 I dont know
