Best Pontiac Powered Super Stockers

[oldskool]

OK, I got another dummy question for you guys who know what the rules were for AHRA & IHRA.

I seem to remember several differences, from NHRA rules.

I have some pics of the 1970 Knafel GTO, nat record holder. It appears to be running in the 2-FA or FA-2 class. So, exactly what is that ? Is it a Stock class ? SS ?

We attended the World Nats race in Amarillo, in '76, IIRC. We saw a car there named "Packin Poncho". It was a '69 GTO, with a hood scoop. Looks like it ran in the SS3 class. Can someone here clarify the AHRA/IHRA rules, for Stock/SS ?

The Knafel GTO was probably running the AHRA Formula Stock class. AHRA considered this a Stock class but was more like Super Stock, hood scoops, aftermarket intakes, any size tire that would fit in the stock wheel well, etc. Formula 1 was for cars with multiple carbs, Formula 2 was for four barrel cars, and Formula 3 was for 2 barrel cars.

IHRA was Super Stock, I believe they were based on the same formula as AHRA Formula stock but had also had a SS/4 class that was for NHRA legal cars.

Thanks ! Don't recall "Formula Stock". Don't think any of the tracks we ran were AHRA.

Questions:

(1) In the multiple carbs class, does that mean you could run either 2 fours, or 3 twos, on cars that came with only 1 carb ?

(2) Does it also mean that you could run a single 2 barrel, on engines that came with a 4 barrel.

(3) Was there any limit as to what brand or size the carbs could be ?

(4) So the Knafel car was probably running a Holley 4 barrel & aftermarket intake, maybe ?

(5) Cam rule for that class ?

Having dabbled in dirt track racing, I can imagine all sorts of big 2-barrel carbs. There were the hogged out 2-barrel Holleys. Then there was also running 1/2 of a Dominator 4-barrel. Would be interesting to know just how quick the 2-barrel cars were, & the exact specs of the carbs used on those quick cars.

Monte Howard was nice enuff to send me some pics & info from the time when he was driving the Ken Shawver '78 SS T/A.

"Indy USNationals class wins 2007, 2010
Norwalk class win 2007
JEGS sports nationals class win 2007
Rt66 Lucas Oil Div win 2008
Indy Fall Classic win 2007
Clay city KY IHRA div Pro-Am win 2007

"The 2010 US Nationals class win was a pretty good story.

We went to Indy with a fresh engine, after our first run it was not quite as fast as I would have liked, second run it was slower. I cut the oil filter apart to find the filter full of bearing material. Not in a very good mood. I sat in the trailer thinking we were done for the weekend, I came up with a idea. Thinking my first qualifying run would get us qualified for the show. I decided to head home and put our spare short block in the car. Left the track at noon on Thursday thinking I could have it back together for first round of the eliminator on Sunday. With the help of good friend Dean Davies we started pulling the engine around 2:00 pm Thursday afternoon. By midnight we had the engine and trans out, pulled the heads, Intake, Cam & Lifters, timing chain, oil pan and pump off the hurt engine. My friend was tired and went home at midnight. He asked how long are you gonna work on it. I said well I am gonna work as late as I could. Knowing that if things went smooth that I might be able to make it back to Indy the next morning for class eliminations . I drug out the spare short block that consisted of a block, crank, rods and pistons. Cleaned up all the parts, degreed the cam in, assembled the rest of the engine and had it in the car and fired up at 3:00 am. Loaded the car and all the tools, went in the house took a shower and slept for 45 minutes and then left for Indy. With only 45 minutes sleep we ended up winning class on Friday with a spare short block that I had to scotch brite the rust out of the cylinder walls.
My friends that I parked with at Indy knew when we left Thursday that our plan was to be back Saturday night or Sunday morning. They where shocked when we pulled back in our pit spot Friday Morning. Bill Rink walked over and asked where I went. I told him the story and he said “you are nuts”."

Wow, I've had more problems with pics on this site than any other. MOST, have to be resized 50% or more smaller. The 2nd pic below was clocked 90° to the left. So, I clocked it 90° to the right, & now it shows up 90° to the right, exactly as it is on my computer. So, I tried it straight up again & see what happened. Anybody know why a pic that is correct on my laptop would show up clocked to the left, when all other pics upload correctly ?

Anyhow, this Bird is definitely one of the most competitive Pontiac powered SS cars ever.

Is there any info on the black 69?
Does it still exist?
My favorite car of all time 1969 GTO. Need to get one again someday.

We saw it at Amarillo back in '75 or '76. It had "Royce Fowler's" on the rear fenders.

I've found other pics that show what appears to be the same car, with someone else's name on the fenders.

A Google search turned up this article which claims the car is a 1-owner car. So, I don't know what the real truth is.

I saw the car at KCIR in 1971 and it had Royce Fowler lettered on the quarter panels. I do not remember the specific class it was entered in, but it ran well.
