Subject: RE: Pistons for 440 crossram wedge My 296 557 mopar purple shaft came today!! Yaaaa. Im so
excited. If it runs as good as i think. I may buy anothr one for my coronet. I
just dont know. I hope to get it installed this week. Course the
engine is still on the stand and i have no car to stick it in but.... who cares.
Open headers on a 440 should rattle the neighbors house to me the
509 cam is about as small as id go. I had a 280 480 hydraulic lunati and
it just ....... chrysler big blocks like more duration i thinks.
Well its my opinion. And around here im developing a reputation for
picking cams for people.

David/Jason,
The Hyd. 284/.484” (241@.050”) 108LC is a
tremendously powerful cam in my 340 Dart but as I remember Don Dulmage saying,
“You can’t overcam a 440” they want long duration and high lift cams. I
don’t think the cam alone is a detriment to performance but an integral part of
the en entire “package.” Every component must work together to meet an
expected outcome. If your expected outcome exceeds a selected “cam” or
package requirement, then you will not meet your goal and be disappointed.
That being said, it is imperative that your compression/head
work/induction/chassis weight and gearing (included trans stall) all “work
efficiently” in the RPM range you selected. Looking back at the build
components of your Big Block is more challenging but consultation with your
engine builder should provide answers; as well as getting your Mopar on the road
to assess “how it runs” and if it meets your expectations.
Regarding the 284/.484” (241@.050”) 108 HYD.
Purple Shaft...its specs “seemingly” appear too large for a warmed over small
block 340 but when you factor the “package” of matched components, it works
splendidly in my application;
3200lb. chassis weight w/o driver
Clutch Sure Grip 3.91 rear gear w/24” tall Drag Radials
Race prepped 904 w/low gear set & manual valve body
3500 stall 10” Continental Convertor
340 w/stock 10.5 to 1 pistons and 2.02/1.60’s with mild head work
1 5/8” Doug Thorley Headers through 2 1/2” exh. pipe & Dynomax
Super Turbos
LD340 intake & 850cfm Thermoquad – haven’t “tuned” the TQ in
25yrs...just plain runs
Chassis Dyno numbers should really put you to sleep if you are “into
numbers”...268 RWHP @ 5700RPM & 277 RWTorque @ 3200RPM...turns quarter in
12.8 @ over 106mph all day long through the muffs
and is a rocket ship on the street...just a fun reliable cruiser.
Therefore, if components are properly matched, your Big Block should really
honk when called on.

Subject: RE: Pistons for 440 crossram wedge When
you get that together I’d really like your opinion on how it runs
privately is fine. I have been around 3 engines of varying
states of performance. And I’m sorry to report not one time did the engine
perform to my satisfaction. One guy just sold the car he was
so disappointed. The other guy same specs. On the motor i.e. 10:1
compression and internal parts 906 heads same junk intake and
all that. swapped cam to the Mopar 509 cam and then I was
pleased with its performance. We had installed the 284-484 purple shaft
based on reasoning that it’s a show car/ driver. 69 general lee
clone. Thing was gutless and we installed a 3500 stall converter to
help it out. yes that helped but still was dead feeling.
Swapped to the bigger cam and suddenly the car has more tire frying performance
and sounds way better. Another buddy had a 284 484 cam in one of his cars
and it slowed down at the strip over a smaller cam they had. So personally
speaking for all the hype the cam has I’ve never seen the performance from
it. maybe just wrong combination I don’t know. that’s why I’m
asking. Plus I’m about to yank the Engle cam in my 65 out and put
something else in. sure it makes torque from the bottom to the top but it
has no “bite” and I get terrible fuel mileage. My
charge 440 with 2 4bbl carbs and 324 duration 550 lift hydraulic cam would
get 10-12 mpg. And I didn’t baby that thing either. But the 65
I do drive sensibly. Sorry
for rambling but I would like to find the magic combination that will make that
284 cam work. Jason From:

On Behalf Of PallCon Services Thanks for info Guys Jason below are cam specs I think but not 100 %
sure. I will check on the KB Hypereutectic
pistons. Hoping to run pump gas as well. Thanks
Gary I will post more pics when I pick up next week.
