I have a very similar setup in my '57. The cam has a longer duration and
not as much lift when compared to the C256 in my truck, but other than
using Weber carbs I have the same intake/exhaust. Very nice power at mid
to high range, and even down at 1000 rpm I can chirp tires in a turn with
the lsd rear end.
There are a couple speed shops out there that make a complete timing set
with no chains at all, just 3 gears in a custom bracket to hold them a the
right location. I've seen it for v8 application, and for old british car
engines, I wonder if a similar item exists for the 235 or even the 230-270
flavor?
Didn't see anything on stovebolt's pages.
