So I got a little more info on the cam today. Roller cam with approximately 488 lift and 306 duration. I plan to swap the cam and I have a local builder that is going to help me with it. I currently have 1.6 roller rockers he is recommending going to 1.5 rockers and a split profile 204 to 214 cam. Does that sound like a good recommendation?

 

1.5 ratio rockers? why would you go smaller than stock? stock is 1.6. 1.7 is the usual go to arm, if you pull intake that will be the tell tale sign, the will be a spyder in the middle with the hold downs, also there is a chance it has a retrofit cam, which has a small base circle for the lobes to make room for the linked lifters

 

no help right now but subbing!
