Had an HP2 440 in my 300J with short rams when I purchased it, 3.91 sure
grip. Got up to speed real quick, but revved it's nut off above 70mph! Often
wondered what one of those new crate 500 inch wedge motors would be like
with a set of short rams, and cast extractors from a J or K. Anyone tried
it?

Karl,
It all depends on the specifications of the "performance" cam selected.
Most "performance" cams have longer duration (valve open time expressed in
crankshaft degrees of rotation) than stock factory cams. This accounts for
their rough idle, loss on low rpm power, and lack of intake manifold vacuum.
The cam supplied in your long ram engine had a rated duration in the 260
degree range. The cams supplied with the short rams were in the 292 degree
range. The longer duration enhanced the ram effect at the higher operating
ranges of the short rams. The lift at the valves was similar for both cams.
What you need for improving your long ram motor is a cam with about the same
duration, but with more valve lift. Opening the door (valves) further will
improve cylinder filling at the rpm range in which the long rams work well
without the undesirable side effects that longer durations impose. Going
from .440" to .540" lift will certainly wake the engine up. Contact any
reputable cam grinder (Isky, Comp Cams, Crane, etc.) and they should be able
to help you select a cam and also what other changes you may need to make to
accomodate the increased lift.

All,

If you weren't able to attend meet in Louisville, you missed a great time.

This was Janet and my first Chrysler 300 Club event and we had a wonderful
time. We wish we had arrived on Wednesday instead of Friday, so we could
have had two additional days of fun and learning. All of the people we
talked (and drank) with, were hospitable and incredibly knowledgeable about
their particular year car and the Chrysler 300 marque in general.....and
what impressed us most is everyone is willing to share their knowledge no
matter how trivial the question might be.

Maybe some of you don't realize, or take for granted, what a unique
organization and wealth of information you have...it took us newcomers about
five minutes to see that this group is worth spending time with. And we plan
on doing just that.

Congrats on a great meet. All of the work and time invested by the various
members was worthwhile.

Ed and Janet Hermes
Cincinnati

The factory that produces Hemi crates Roger!!
p.s. Chrysler is well known for underating the HP on their motors and this
one is rated at 550 from the factory ROGER!!!

Hughes Cam ( http://www.hughesengines.com/cams/bhydflatlist.asp )
recommended a HE3038BL for a long ram motor I am building for a '60
Plymouth. This one has a 223° @.050", .504" intake and a 230° @.050", .538"
exhaust spec. Should you call them, be prepared to answer a lot of
questions about your application.
