440 Camshaft drive FAIL!!!
So our rebuilt 440 with only 300 miles (at most) on it, developed a problem when stopping at a traffic light, it wouldn't idle. It had lost 20 deg. of ignition timing, so we twisted the distributor, and it ran well again. Then a short time later it did the same thing again, another 20 deg. of timing lost. We couldn't twist the distributor far enough, so had to pull and adjust the drive gear, to get it firing at the right time, but this time it wouldn't run quite right, and lost top end power. We tried everything a group of us could think of, but in the end pulled off the timing cover, to discover that the single bolt drive with 1 locating pin had suffered a major failure! We hope no valves are bent, but are still determining that, 2 chrome moly pushrods are bent, the timing sprocket is trashed, and we are NOT Amused!!! These were all brand new name brand parts, so why did they fail??? We will be going with a 3 bolt camshaft sprocket retainer this time!

Preston Herrick's "Blown" 440 Duster - Initial fire-up
Highlights from initial fire-up. Assembled another '70 440 shortblock with lower compression (8.5:1) Speed Pro forged pistons. Topped off with 6-71 Supercharger and dual 750 Edelbrocks. Waiting for electric pusher fan to arrive - no space for anything between radiator and blower drive. Can already tell this will be a different beast from the NA 440 it replaces.
