Not about equal...
It is about developing products for S and SS.
Those are capital systems...

You comment is off the mark.
You could say the same thing about Stockers using Roller Lifters making things equal..!

This was going to happen sooner or later.
Stock morphed from using all stock factory parts to custom built everything.
So much that custom blocks have to be made to keep things Equal!

NHRA now allows Solid Lifters...come on!
What is next?

Staying Pure Stock or Crate Motor are looking better everyday.

What do you call it today.. Junior Super Stock with 8000 rpm shifts
Or
Junior Modified Production Super Stock with 12000 rpm shifts
More safety gear and Roll bars and stuff pro level cars have?

Sooner or later NHRA is going to give these classes hair cuts.
Too much, too fast and more Insurance to cover risk!

That's a good idea Dan, stay Pure Stock and enjoy racing your car that way.

Hey Dan, if it was not for Veterans you would have no rights. Go play soccer!!!!!

[Alan Roehrich]

Fahey, you obviously like nothing about NHRA Stock Eliminator. So how about you stop trying to change it, shut your pie hole, and go race somewhere else?

[Lee Valentine]

Here's how I do it,I look at the rules and say that's the eliminator I want to run. I accept what I'm in for and don't try to change everything. If you can't accept the rules go do something else.

I have a question for whoever dreamed up the need for replacement heads for SBC engines. How do you think it is easier to find a 624 head for a 1986 350 truck than a 1979 Chevy car with a 350? How did you determine 62-79 SBC are the only engines affected? I also like to know how we are going to shrink an intake runner from 185cc to 172cc legally? MERRY CHRISTMAS & HAPPY NEW YEAR
