Polyheads,
The HEMI to Poly engine modification is no mystery and I have known about
it for over 40yrs. (see the 1956 Fury Daytona Beach Race articles...) but have
not invested any time creating the package/mods necessary to bolt the HEMI
intake onto a 318 Poly. At that time Weiand still produced the #7503 and
plenty of OEM and aftermarket Poly intakes were affordably available at swap
meets and online. This has all changed in the last couple years and truly
requires the entrance of a viable and affordable alternative – the modification
option w/separate valley pan and water neck outlet mod or a totally new Poly
intake casting complete and ready to bolt-on. My personal projects have
deferred my time for this endeavor but as of late several more enthusiastic and
mechanically inclined friends have urged the previously “backburner” intake
project to the present.
This is a concerted effort that owes its impetus to Roland Osbourne of
Chrysler Power Magazine to whom the merits of Poly-power amazed him and thus the
enthusiasm grows to a roar with his many industry contacts. Gary Stauffer
of QEC Engineering (HEMI fame) is extremely talented in the technical realm and
brings much to the idea table in this project as well. I have the most
experience regarding the Poly engine and simply revealed what Chrysler engineers
did in 1956 to propel the 303 cid Poly in a 1956 Fury to over 143mph one way on
the beach that year. Couple the simple mod of adding a cast iron dual quad
HEMI intake to the Poly 318 engine and you can see what is possible now by
looking back to what yesterday’s engineers have done. The HEMI intake is
near dead on center with the port spacing compared to a Poly engine so this is a
very easy casting modification in my mind and the other “differences” are minor
– to my thinking – and should be a piece of cake for an experienced foundry to
take the Hot Heads HEMI intake and pattern a new 4bbl. Air Gap style Poly
intake. Our foundry meeting on Monday, Oct. 14th will determine
(hopefully) the affordability of casting a true bolt-on Poly intake or
necessitate the need for a “kit” to adapt the HEMI manifold; I am
lobbying/urging the creation of a true bolt on manifold – cost will determine
this as we want this to be affordable and easy for Poly engine owners. I
am more than hopeful this will transpire; either way, there will be a Poly
intake available that will be superior in every way over the current single carb
options. Yes, if a single four can be successfully cast, multi-carb
manifolds (and more) will follow.
I hope I have explained our current project status and answered questions
posed and other questions yet unasked.
Respectfully,
Gary Pavlovich

Subject: Re: Poly 4bbl Intake Gary has been working on this for a couple of years now I thought he
would have clued us in to new product and the necessary hardware to install it.
So we will have to bounce this off him and see what he says! If he says
buy I will be also!
