Think I found why my car's a gutless turd.

The modern 'high rate' cams are not the problem; they have been around for decades. The problem is the crap lifters, poor metallurgy & inaccurate machining.

I've see several people test various modern lifters against decades old NOS, and they're the same as far as hardness. Machining, however, a different story. A number of lifters were surfaced very poorly, wrong angles, and inconsistent surface. I used to regrind lifters just out of highschool, and for the life of me, I don't know how anyone can **** it up unless the machine was so worn out the lifters were wobbling around.
