Anyone running Comp XE295HL cam?

[91r/t]

Looking to see peoples opinions on this cam. I have one in my Charger with the 500 in. stroker (440 block) and am curious how everyone likes the cam. Is it really that big of a cam? Mine idles kinda tame with the stroker but duration looks rather large for the street. My car is a 4 speed.

That’s probaly 1 step below their “Drag race” grinds. the 110 Lsa should keep the idle somewhat tame for street use. Duration @.050 isn’t too crazy for a street cam. I’d bet it sounds mean! Got a video of yours running?

The issue is the catalog is basing the rpm and power bands on stock stroke packages. The longer the stroke, the smaller the cam will act. Your stroker will be fine idling and pull well off idle with it.

no videos yet as its 30 and snowing outside right now

This video is a bit more lumpy because the carb was super rich and causing it to lope a bit but its close to what it sounds like. idles a bit smoother now though.

Duration at the seat is not near as big as an ISKY 310 Megacam more than 20 degrees smaller
You tell us how you like it
post the details on weight, gears, where you drive it
should be great on mountain roads or passing on the freeway
not anywhere near a race cam
for comparison Engle K8 which I have used a lot is 249 @.050 with 367 cam lift
Advertised duration is at .008 296 - would be over 300 measured @.006 like comp
With the additional seat duration the K8 is not going to be as "intense" as the COMP
The k8 cam wears well and is not a "close to the edge of the lifter" design (round lifter gets less arc area from the essentially linear tappet as you get closer to the edge giving more unit pressure- you can get away with more on the closing side than the opening. think about it
Isky Mega (let me try and remember- it's different for every Isky cam family) .009 on the opening side and .010 on the closing...designed for chevy
The Isky and Engle designs date from way back when springs were not nearly as good- hopefully we have learned something in the last 40 years

The car runs great and does 30 mph burnouts so that's a plus! It has 3.91 gears. It is all stock mostly so weight would be the same as that was. I do alot of back road driving and a little thruway but more back road 60mph cruising. Your cam talk basically was like speaking Japanese to me on a drunken evening! Hahahah! I understand the basics but yea all that in depth cam talk I get lost. I can build an engine from scratch and pick a decent street cam, but the specifics like that I leave to the cam guru's.

Stupid questio, but Could you explain the difference in advertised duration and duration @.050 why do they list both of these within cam specs.

 

[wyrmrider]

you're now the expert on the comp 295
I took a quick look at the chevy grind Isky 304 Mega
Value Lift Int/Ext: .525/.525
ADV Duration Int/Ext: 304/304
.050 Duration Int/Ext: 256/256
so about the same at .050 as your cam but the seat timing is MUCH greater- maybe 15-20 degrees more with an apples to apples comparison
and you get much more lift- area under the curve
A GREAT EXAMPLE on why NOT to buy chevy cams for your MOPAR

GREAT QUESTION
the .050 came about to have at least one way to compare cams and a way to degree cams in
I'll post later on the problems with .050

As I've shown above advertised hydraulics measure duration at widely different lifts off the base circle
I showed Isky using .009 on the opening and .010 on the closing- Engle using .008. Comp and many others using .006 and Crane .004
If Isky had used Cranes method that 304 cam would be over 320.
The white box cams ELGIN, Sealed Power, TRW, etc use .006 off the Valve seat which is the best way to compare as it factors in rocker ratio.
This is called the SAE method. With a 1.5 rocker Crane at .004 at the lifter is the same as .006 at the valve.
So you have to have a feel for the fudge factors to compare advertised durations
And, Saving the Best for Last, CHRYSLER and MOPAR use a different and unique method...not comparable with any of the above but consistent across the Brand
