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

Triple Black Attack: 1970 440 6-Pack 'Cuda - /BIG MUSCLE
Each and every muscle car enthusiast has that one experience that has
helped define the way in which they view the automobile. For Northern
California's John Cross that experience came by way of riding in the back
of his cousins 1970 440 6-Pack Plymouth 'Cuda when he was a kid. It was a
car that provided him with memories, stories and of course, a goal - that
being, to one day own the very car which got his engine running all those
years ago. It's now 2012, 42 years after that first faithful ride in the
very 'Cuda you're about to see. This time however it resides in John's
garage, not his cousins, which can mean only one thing... Sometimes dreams
do come true.
