True Horsepower Classes in NHRA

Yes there is a class for you to go faster. It is called Super Stock. That's where special built factory racecars that were never legal to be licensed for the street belonged in the first place. Stock eliminator does not need 8 second/160 MPH cars chasing slower classed cars.

Correct me if I'm wrong, but I truly fail to see the difference in factory involvement now compared to factory involvement in the '60's and early 70's...... Didn't they also build limited production, factory racecars then that dominated stock?
I understand that "traditional" Stock Eliminator racers don't seem to care that much for the newer cars. It seems to me that they would welcome them and the new racers and fans that they attract with open arms. I do see the need to keep the indexes fair in order to keep the older cars competitive, but beyond that, see no issues.
I guess 40 years from now, the guys still racing the currently new crop of factory cars will be complaining about the 4 second nuclear powered factory race cars having no place in Stock Eliminator, lol.


Rant over.

Let's look at the limited production early factory racecars and where they actually ran.

63 Z11 Impalas ran FX, 63-64 max wedge Mopars ran S/S, 64 Thunderbolts ran S/S, 65 race hemi Plymouths and Dodges ran S/S, 68 hemi Darts and Barracudas ran S/S, 69 AMX with crossrams ran S/S. None of these limited production factory racecars were legal for stock classes yet they had serial numbers and although it was not recommended, did get licensed for the street in a few cases.

Can't do that with todays limited production factory racecars that have been allowed to run in Stock. They should be running in S/S only.

I am never sure what the HP rating is all about. Only thing I can imagine is a reason for someone to buy a new car. Newer factors are always a guess. (Usually off by 100 or more HP).Even the old cars lurking in the books are found to be off by many hp and that's why people day dream of dominating by building them. Once they are built and paid for a different combo surfaces and many "perfect combinations" become also rans. This is the long term fault of the lb/HP classification method but it is the only way to get apples, oranges and bananas into a class system to race together.
Many people miss Modified where is was lb/cubic inchs. This took away the fact your combo was falsely factored and that's why you lost the race. Some complain that money affected these classes but maybe people should look again at the costs of a new Stocker from the factory which cannot be licensed if it fails to win.

How many Hp does a new 427, 425 hp rated Copo motor make? Anyone? Might that be a wonderful motor in an old car?

[Mike Keener]

Every dyno is different Dick but a reasonable figure for a 427/430 COPO is in the 810 range. A shootout 427/450 version is around 880 ish.

There again every dyno is different

[Mike Keener]

These figures in my previous post are for true Stock Eliminatior engines. A Super Stock motor may be worth another 75 or so if it is maxed out.
