Another D/Dart 275/273 question???

Back in early 1966,

Chrysler Performance also tried out the Holley #3116, 600 CFM (1965 Race Hemi) carburetor,
before going to the Holley #4778, 700 CFM unit.


The Holley carb number is #3778.

Also, the actual Chrysler cam drawing indicates the lobe lift was .32773/.33433 which equates to .492/.501 valve lift. On a second cam drawing it indicates the valve lift as .493/.503.

Per the notes on the 24 time slips (test and tune sessions) that I have from my car, Ralph Costa shifted to 2nd and 3rd at 6700 RPM's and into 4th at 6800. He went through the traps at 7000 RPM's. Tire pressures were from 9 to 14 lbs. Distributor was run from 36-39 degrees. The testing was performed at Milan, Detroit Dragway, and National Trail Raceway. The best ET numbers on the slips is a 12.92, and a best MPH is 105.
