It consisted of PURPOSLY creating vacuum leaks on 2-b 265 and 283 Chevys using numerous techniques. Some 273 Mopars also benefited from the crafty trick. The vacuum leak/s were (necessarily) accompanied by MUCH-RICHER carb jetting, which created (practically) the net-effect of a 3-b carb. The most blatant method I ever saw was on a 61 170/283 where a garden-hose spigot, complete with handle was installed on the intake. This allowed for a last-minute wide-open 'adjustment' right before a run. Tricky folks, those Junior Stock racers!
Best one I heard was a guy who's no longer with us, had about a 5/8 heater hose running to a vacuum gauge just under his dash. He'd leave the line, then reach down and pull the hose off! That trick works with 4 GC carbs too, by the way .You would richen up the secondary about 10 thou. Once in the staging lanes, you would reach around the back of the carb and take the 1/4 pipe plug right out of it. You just would have to wait until everyone else started theirs up to move forward in the lanes...It made quite a whistling noise. Worth about a tenth of a second. Of course this is all unsubstantiated rumor here...
I remember when the tech guys started spraying either around the manifolds to see if there were any air leaks when the engine was running. Another trick was keeping your air filter in a cooler with dry ice until you were ready to make a run. The air filter was full of poly propylene and once the engine warmed up it sucked it through the engine. Jimbo
I don't remember any GTO running in H/Stock. They had a high rating and bogus light shipping weight. B,C, D, E Stock maybe
I'm thinking that's Doc's Black Arrow 442, Woodland & Andresen's string of 442's were all painted the factory Burgundy color... Dyno Dave
Yes, and Doc's cars were all painted white...but that's where he got it from. Notice the Tubular Automotive headers. I suspect the Chrysler deal was over at this point, especially without Jenkins. Remember ,W&A were dealer sponsored and got a new car every year.
If my memory is still working I believe that Doc Burgess was a veterinarian in Dover Plains area of New York State. I think it was son Richie Burgess raced in the old Darlington Dash Series in NASCAR back in the 70's and early 80's Some people don't remember that Bill Jenkins raced the old "Black Arrow" car. Just my opinion. Jimbo
Junior Stock cars looked just like cars many of our parents had and that is part of what made the class so popular. tommyd a million thanks for all the great photo's Jimbo
