Has anyone changed their cam on a SP700? I was wanting to find some more performance.
Need to know if I need to plan on changing valve springs or anything else with the added lift and duration of a new cam.

And also is their much improvement over the stock cam?

 

I got one in my 700 carb and it really adds some tourqe. I'm not for sure but I don't think they make one for the EFI.
