So I picked up a set of heads the other day with a set of 1.6 full rollers on it. I then just wondered what the deal was if the desire was there to put the 1.6s on the SC with a larger cam. I mean, with my 351, I checked the lift. With my 1.7s, I had .001 higher lift with my .498 cam than I would have had with a .512 cam and 1.6s.
So, can you run a larger cam with 1.6s and have better valve stability from a lighter overall rocker weight?
I believe the factory ratio is 1.6:1. So, lift the cam to what extent? Is it because the lifter is too high in the bore at max lift? Is it because the 1.7s can have a better (cheaper cam profile) cam than can be obtained with the 1.6s?
Discuss.
