Crate Motor Pure Stock

Figure a stock 4v manifold could be easily bolted on.
Replacing the 2v and move up a few classes.

Maybe Crate Motor was not the best way to start the conversation.

My intent was to consider doable combinations, or upgrade.
Still would have to meet all the other Pure Stock rules.

The advantage you already have existing engine data.
Plus how it would perform.
Would not want to see BB put into a car that came with a SB.

For example always thought Ford lost an opportunity to put a 4v on the Mavericks and Mustang II's.

Think it would be interesting installing a Corvette Triple or Dual Carb on a 350/255 using a stock PS cam.

A 409/425 in a 1969 Chevy...!!
Has to meet Pure Stock cam rules.

It would make things look interesting to the public who like to look at our rides.

Dan,

I like the idea. Sounds a little like the old Formula Stock classes of AHRA/IHRA some 35-40 years ago. You could put different combinations of engines or transmissions in cars that never came with them.

I remember Bunker Hill here in Indiana had a series of classes that allowed you to change intakes and carburetors on stock engines. This was in the early 70's. Guys got carried away with cam changes and such. Was hard to police.

Like the proposal for a watered down version of the old Super Modified class that was bandied about here last year. It would have to be done at a local level. NHRA isn't going to add more classes. IHRA already has a bunch.

You can't run old cars in stock gt. I think 82 and newer body. Rule didn't get changed when they did away with year rule in super stock.

1980-newer cars; 1979-older engines in IHRA Stock GT. That was the original intent of NHRA SS/GT, which has since changed to any year car and engine.

A rule change like that for IHRA Stk/GT would likely bring in a lot of new F/X motors into it. Be careful what you wish for.

No to any new classes in Stock is my vote.

Since the non-VIN F/X cars didn't show up until 2008, how about this:

Any 2007 and older Stock engine into any year vehicle in the classification guide.

That way none of the new F/X CNC ported cylinder heads, huge throttle bodies, and big roller cam combos are allowed.

I know IHRA will probably never do it, but it is fun thinking of the possible combos.

Honestly who in IHRA can still check a pure stocker camshaft?

[Mark Yacavone]

Do the IHRA Crate specs include duration and overlap?
You would need them for something like this.

Some are common such as ZZ3 cam

Me but I retired about 12-13 plus years ago.....LOL. I taught Hank Blakenship but he passed away. I think your dad used to do it??? Jim Woods has emailed me a few times to get together for a teaching session but he never followed up on it. Its not hard to do but its a giant pain in the butt. Especially on newer cars. I look for classes that need this done to go away soon. It seems that no one cares to do the job anymore. To time consuming and to much work. NHRA stopped in 1986.
LIMITING VALVE SPRING PRESSURES WOULD PUT A LIMIT ON HOW WILD DURATION AND OVER LAP COULD GET AND STOP THE CRAZY EXPENSIVE LIFTER BS.......EASY TO CHECK BUT I DOUBT IT WILL HAPPEN. Its all ancient history.

Where did the "Pure" go?

And what exactly would be STOCK about that? Since the closest IHRA track to me is over 10 hours away, I have never ran any IHRA races, so I personally don`t care, but when I look at my Nitro Joe stats, it seems to me that IHRA already has far too many classes in their interpetation of Stock Eliminator, and far too few racers that run in Stock as it is. I can`t see ever further watering down of the class being a good thng.
