I came across that same Photo in the past

Yes.

Mike wanted to no: What is a Superspeedway and what makes it different from regular speedways?

The beauty of NASCAR is the different types of tracks that they visit on their schedule each season. While most of the tracks are speedways, there are also road courses and the beloved superspeedways. Just what is a superspeedway however?

A superspeedway is a track that is greater than two miles. In NASCAR, the most memorable tracks are superspeedways, including Talladega, Indianapolis and Daytona. What makes the races at these larger tracks so exciting is the high speeds and wide track.

With higher speeds and wider tracks, some of the most exciting finishes in NASCAR history have occurred at superspeedways. There are also safety measurements put in place at these races as well.

With high speeds and driver safety of the highest importance for NASCAR, these races are generally restrictor-plate races and therefore the speeds are reduced a bit under what they could be. Despite restrictor plates being used at these races, there have been some crazy wrecks over the year and it’s led to more restrictions.

The long tracks will live in history and they take plenty of experience to master. Superspeedways offer the best challenges in regards to fuel strategy and even the best drivers have fallen victim to not having enough fuel in these races.

There’s just so much involved in these larger tracks, that it really makes NASCAR all that more intriguing to new fans looking to get into the sport.

Keith, is that Mac McKellar in the hat standing next to the Car in the Photo?

Yes.

Jeff Denison brought Mac and his car out that day for what would be his last Widetrackers Dustoff.

That is funny that you posted that picture of the Pontiac Grand Prix Steam Car. My dad worked on that project at GM Research. This was in 1968 and 1969. It actually ran under its own power around the lake at the Warren Tech Center, in Warren Michigan. The car is still around. The last time I saw it was in the GM Heritage Museum. GM Research tried many other crazy and different ideas for vehicles in everything from powertrains to technology. Once in a while they have a night where they let a limited number of employees and guests tour the museum. My dad saw it and immediately went over to it. He was telling me stories of it being built and a crowd gathered and everyone was listening. That was the first time the museum people had someone who worked on that car come in and know details about it. He worked at GM Research from 1960 until 2009. He almost got 50 years in. I have been there since 1986.

(A) I have the 1966 Rochester Tri-Power (3) large Bore Flange Carbs. over the cast Steel Intake Manifold, what is my CFM?

(B) I am "not" as familiar with this process (Super Duty Project) although I down loaded the sites that you are working with, I have "not" had a chance to read how all this works. Goes from Drafting to Models to Prototypes then Testing then Billet man makes his own SD Intake off the Model. "What is a Pattern that is needed to continue in making the SD Intake Manifold"?
Given:
Base (bores) - Venturi - CFM 2bbl (4bbl equivalent)
(1) 1.25" (1-7/16") - 1-3/32" - 278cfm (197cfm)
(2) 1.25" (1-7/16") - 1-7/32" - 311cfm (220cfm)
(3) 1.5" (1-11/16") - 1-3/32" - 278cfm (197cfm)
(4) 1.5" (1-11/16") - 1-3/16" - 352cfm (249cfm)
(5) 1.5" (1-11/16") - 1-1/4" - 381cfm (269cfm)
(6) 1.5" (1-11/16") - 1-5/16" - 423cfm (299cfm)
(7) 1.5" (1-11/16") - 1-3/8" - 435cfm (308cfm)


Given:
CFM is Measured @ 1.5" HG for 4 bbl Carbs. , CFM is Measured @ 3.0" HG for 2 and 1 bbl carbs.

Note: I hope the information is correct from the internet?


Note: I remember 1200 when you add each carbs. CFM up, I did not actually measure the Venturis, just going from memory in the past.

(C) By using the Information above, my center Carb is # 7 and the two outer Carbs. are # 5's, one should be able to figure out my approx. CFM using the correct formula (that I can't remember).

Mike needs: Questions A, B, C and D answered please.





Given:
Mike Learned: By watching a video Wagner was speaking about the Tri-Power Progressive Linkage adjustment especially about its flexibility. I set mine according to information at my disposal at the time. We adjusted the Throttle opening for the secondaries at 70 percent.

Then we set the Passing Gear Detent solenoid to activate at 90 percent opening according to the instructions that came with the B+M Switch. Here is what happens: The Vehicle is moving at 60 MPH I step hard on the accelerator and the car reaches 90 MPH and throws me back into the seat up to 120 MPH and slowly moves up to 130 tops.

Now Wangers said in his video that I can re-adjust the Linkage if I have manual linkage, and I do. Then I read on the Forum that member sets his Linkage to 40 Percent. So, I want to set the linkage back to operate in a normal street- able setting because my tires are only speed rated to 80 MPH consistent speed.


(D) "How do I set my Tri-Power Linkage adjustment for best performance in a street usage and Highway driving"?

P.S That speed listed above was with the old worn # 886 Cam, I now have a "041" Cam installed with the Cam timing set @ 109 degrees C/L plus a new HD Torque Converter from Hughes.

I Flushed and serviced the TH 400 Trans., while I was at it and installed a new B+M shift kit, plus, I added three different types of additives to the Fluid. We added a second remote Trans. Filter for added protection. I use the Radiator Trans. cooler as well as a remote air cooler to keep my fluid temps. down to about 160-180 degrees F.

Padgett : "You don't count the Carter built Quadrajets"?

I am not sure what the question is here, I just learned that Carter subbed out Rochester Quadra jets from the Factory myself, I think. Remember, I get this stuff on the Internet and post it. Now, if you're talking about the list that is an ongoing forum thing and people add to that list. It is by no means finished nor did I edit everything so I can post the Text in the future. I will delete all the bull and narrow down the meat of the subject when I can get to it. If there is something you need ask and I can look through the long forum stuff I downloaded and had not read yet. As I said, I am not sure what you're asking for, your message is too vague or short for me to comprehend. Mike out.
