Re: Hemi Head Ruling

RPM is the killer here....i may be wrong but if the intake rule had been enforced then the need for such crazy head flow would ouf been lesser..
wonder what the cars would be running if we went back to real crossrams...and would it affect the rpms that seem to be the norm now??? david???charlie???....need a rule like farm boy pullin tractors have???rpm telltale ...limit to 8800

The rpm their running probably has much more to do with the valvetrain innovation than anything else I think. Between Charlie and David, they have gotten the valvetrain much better in recent years.

On another note, is Super Stock another world where your only going fast if your cheating(knowingly breaking/stretching rules)?

Re: Hemi Head Ruling

The biggest problem with this rule right now is the way it is written. It leaves way too much room for interpretation! With the creativity and $ in AH right now, it may start initially as a 1 inch manifold spacer, but how long until the spacer is 3 inches with the inner had studs being utilized and it actually serves as the rocker stand! The only thing stopping it is the combustion chamber and its just a matter of time before it becomes a section of that. That will make cc'ing a Hemi head in tear down fun!

Re: Hemi Head Ruling

I remember seeing this done by Richard Maskin with his pro stock Rambler (hornet) before the 500 inch rule came into play. It transformed the port from useless to a player. This was brilliant ( i thought ) at that time

AH Hemi heads don't need this technology to go fast.

Cheaters and Losers"

Re: Hemi Head Ruling

Bringing back the crossram might solve the controversies of SS/AH.
What do you think?

I was a rookie with a fairly fast car (R&M’s 1st attempt), number six Q I think behind the Hatfield & McCoy team cars. I went red in round two against a young “Top Gun” driver for the McCoys. I was actually faster than him on that run. That’s why I support the win on a red light rule mentioned in the first post. He was Maverick and Ice Man all rolled into one. The Hatfield cars had left the night before as gravity had relocated their #1 intake valves to unwelcome areas of their motors. So I just watched in awe as the young driver mowed down one side of the ladder while their other McCoy team car “took care of business” on the other side. They were destined to be in the final. The young man was rapidly becoming my idol and hopefully my mentor one day. Then right before the semis a small riot seemed to be starting at his rig. I scurried over to see what was happening. Someone shouted “Where the heck did he get that tall hood scoop, from the movie CARS??” The young man calmly said “Fellas, fellas wait just a minute.” He moseyed (we mosey in the South), he moseyed into the stacker and came out with ANOTHER (YES ANOTHER) perfectly painted matching hood with a legal 4 inch scoop to CALM the masses and finish the race. NHRA said NOProblemO. WOW! I had heard stories of an old hemi car in the Northeast called “Two Scoop Lido” but I was standing in the presence of none other than TWO SCOOP DAVE. Man, I would be honored to pay to letter that on his many famous cars. I asked my car builder John why I didn’t have two hoods? Did everyone go to Indy with two hoods?? “NOPE, not needed if you have the correct 4” scoop” he said .
Now on a serious note Two Scoop, you “kicked this skunk” starting this “holier than thou” thread calling people cheaters. I have never seen Charlie or his Dad changing hoods in a race. Their arbor was somewhat hidden. My chrome bolts were not as this was a car show and a drag race broke out. As for me, I have my cheater letter and ya’ll can call me “Screwhead Steve”. Welcome to the fraternity.

Stephen, nice story. You lost me in a few places but I get the gist of it. The only problem is your facts are distorted.

#1 - Your dates are mixed up. It wasn't the year the Westcott's left. It was 2009. How do I know that? Because I raced Westcott Sr in the final and I'll never forget how the car died when I floored it. It was also the last time I saw Paul Wilson, who really made a big deal about this whole hood scoop thing. Which I was completely fine with because it was bringing some excitement into the pits. I believe Bales was pretty fired up about it as well.

#2 - The other big hole in your story is the fact about the hood scoop. The whole idea behind the different hood was to see how narrow we could make the scoop, not how tall. The whole idea was to grab less air. Going taller is the opposite of what we were trying to accomplish. You really think I'd be dumb enough to try going taller? That was tried way before you came along. I'd have to say the craziest one I ever saw was the one Sid Bonnecarre had on Teuton's Dart. I'm sure it was more to prove a point.

Last I checked there was no rule stating how narrow the hood could be. Since I've been racing I've seen NHRA measure those hoods every way possible but they fail to put in writing just how big or small they should be.

Anyway, somebody noticed mine looked different. After 3rd round Bruce asked me what the big hype was about the hood. I told him ours was narrowed a little bit. I asked him how narrow it was supposed to be and he had no answer. He then asked if I had another hood. I told him yes. He then asked if I can replace it to get everyone off his back. Out of respect I said no problem. I figured if everyone was so fired up about it, I better not win the race with it. And by that point I felt it was no gain anyway.

Can't we just be friends, Stephen? I don't like when we fight like this.

Re: Hemi Head Ruling

This all reminds me of the 70's pro stock twist/tweak of the heads and rules of the week. Then again in 90's with PST. If it still had OEM part numbers then it must be legal. LOL

Re: Hemi Head Ruling

Of course we are friends and the bolts (screws) in my head have me mixed up on things for sure. Shoot man, I am OLD. I guess this means you guys are RSVP for the KKFC $10k deal?? Finally get all this out in the public.

PS Just edit my story for year and hood width vs height. I apologize for being incorrect. Stephen
