"... i am going to get an 068, mainly cause of the lower lift for my pressed in studs..."
This is a quote from the OP. So, which of the modern cam grinds will work, SAFELY, with press-in studs ?
I think that is the question. I don't think anybody doubts that there are LOTS of cams that will make more power than the 068. BUT, if you use enuff spring pressure for these newer grind cams, will a stud be in danger of pulling out ?
Can you get by with 100lbs + installed and near 300 open ?
And, some guys here recommend using a stronger spring than you really need, because they will lose some pressure, with use. A pulled stud, on a running engine is no fun.
