Just so those of you who have never run up on the mountain can appreciate how fast the '08 Cobra Jets are, the A/SA car driven by Chad Holzman ran 10.51 at 133 mph on Sunday in air that most of you probably can't appreciate. My Performair said the barometer was 24.15" absolute, temp of 70 degrees, 44% relative humidity with a vapor pressure of .33 and a barometric pressure of 8500 feet. This is actually pretty good air for Bandimere. Using the altitude correction factors, this is a 9.74 et at 143 mph at S.L. The et, while REALLY fast is nothing compared to the MPH. That's the real indicator of the HP these cars can make. Their 60' times were in the 1.41-1.42 range which is soft considreing the ET and MPH. My 'Paper Car' 64 Hemi could only muster an embarrassingly slow 10.92 at 122. That was a measly 1.25 under the index. Guess I just need to work a little harder on the car to find that next 11 MPH.
By the way Larry, I have two original '043' 64 Hemi intakes, the early one was aluminum, the later version magnesium. They clearly were the predecessor to the '66 Street Hemi intake. The 'Bathtub' intake didn't come along until early '65 and were run after the NASCAR ban on the Hemi and SOHC Fords were lifted in '66. They were the Long Track manifolds. Darrell Davis has published a book that details by VIN number the 64 Hemi cars that were built with steel front ends and aluminum scoops and high compression engines, and these were the cars that were shipped to NASCAR and USAC to race. Wesley Roberson spend a week verifying all of this with Chrysler and former NASCAR racers before the last tech revision was listed in the Stock Car Classification Guide. GEEZ, I hope I didn't just wreck the notion of these being Paper Cars!!! I sooo like the sound of it.
