Is anyone familiar with this intake ?

[hemi_cuda71]

This is an intake Ive had in my collection since the 70's. I used it for SS/D racing. It has the same casting numbers as a stock intake but no pentastar. In the side by side photo, its the one on the left. I thin the logo is DCPD (possibly early Direct Connection Performance Division ?? ) Any insight would be appreciated.

Thanks

I don't know anything about your manifold, but the DCPD logo doesn't stand for Direct Connection Performance Division. It stands for Dodge Chrysler Plymouth Desoto and was around before Direct Connection even existed. It even predates the pentastar logo.

======================================
First off , '393Heminut' is correct about the "DCPD" casting mark standing
for "Dodge-Chrysler-Plymouth-Desoto". Secondly, about the intake itself. It
appears that the only difference between it and the standard piece is
the open plenum. There are two possibilities. Opening up the plenum by
grinding away the stock 4-hole carb flange and removing the divider was
a very common 'race' modification back in the 60's and 70's for otherwise
stock Hemi intakes. Doing this, combined with re-jetting the carbs a bit
richer to compensate for the somewhat weaker signal to the carbs caused
by removing the divider, significantly increased top-end horsepower. but
at the expense of some low-end torque. The modification became so
common with some racers that I think Chrysler, for a while, even offored
some intakes for sale, over the counter with this modification already
done. Your intake could be either a home-brew, owner modified piece,
or one modified by Chrysler and sold over the counter. Either way, not
much difference.and probably not possible to verify one way or the
other.

Isn't this what is commonly referred to as the "VANKE" manifold? It was a modification originally done on some manifolds for the '67 WO27 racecars.

Yes that is the Vanke mod, named after Arlen Vanke, one of the factory sponsored drag racers, who was the first to modify the intake. I don't think there is any way to determine it's origin as it was a pretty common mod back in the late 60's early 70's. The DPCD logo is an early intake pre-68 and the pentastar intake is later 68 and up I think.
