bullitstang1313 said:As far as cam, you might call a cam manufacturer or cam machinist to see what kind of custom cam would be a good setup. As far as foller rockers go, you'll need to make sure that you don't have any piston to valve clearance. 1.6 are the stock ratio. Good luck with all of this and welcome to Stangnet.
So is this ratio directly related to the heads/cam I use or is there different way to measure or know which one you need or if you could reuse the stock ones?
, cause I have seen some sigs with explorer parts or explorer 31spline rear ends...
