Oh boy...you have a lot to learn about camshaft design; agressive lobes are not required to make lots of power. Not every stocker cam grind works the same because there are lots of factors that need to be taken in consideration.

The reward : an engine and revs high and makes big power throught the range, resulting in Fast ET's, good quailfying stats.

Another falacy...there are lots of engines that do not need to be twisted to higher RPM's to run fast because they are limited on its design. Ask anyone that races a Buick engine or a late model Mustang 302 F.I....they cannot spin their engines due to breathing limitations.

You can have a guy in Tech have an on the car valve spring checker. He he pulls it on the car and the pressure is way over he's out.

Keep dreaming.

Guys back in the 70's and 80's had no Shubecks, or big valve springs. They survived and raced.

I do not know how old you are, but I have been doing this for a very long time. In the early days, even with the spring limitations and old cam specs, you still had failures.

What happens when engines are running super high RPM and they start coming apart, will guys start lobbying for lightend bottom ends because it's a safety factor???

Why do you think NHRA put weight limits on the reciprocating mass?

I'm sure of it. This is not an easy game, guys been playing for along time within the rules and being succesful.

Like I said, I have been in this sport for over 35 years and playing for a long time and have seen the evolution of the rules. When there is a rule change, you adapt to be competitive.

SOME of the racers of today don't want to make what they have works, so they Bitch and cry for rule changes because they ran out of talent, money and the will to make due with whats available. This is what stock is about.

Your statement is sort of an insult to many of the well respected engine builder in Class racing that are busting their asses. They have expereinced rocker arm failures too like everybody else. Just do a search, read the posts and edify yourself.

In a nutshell, if you read many of my earlier posts, I have made it VERY CLEAR, that the problem with stamped rocker arms is the QUALITY of the product. We live in a global world were parts manufacturers are outsourcing parts overseas. The process is not the same as in the early days, they are producing a lower quality product, with cheaper labor and processes. By the way, I know of two particular cars that are running a cam grind that was designed before the camshaft rule change and they are also breaking rocker arms too.
