Hi, I have a 440 engine with mopar 452 alu heads (84cc),flat pistons .030 over with a 0.086" deck clearance and a set of 0.039" head gaskets. I have used a CR calculator and i got a result of 8.98:1 CR The car is a 69´Charger 4-speed with 3.55 gear I don,t understand very much about cams so somebody said to me that this would work ok with my set up,since i want a street car,nothing for the track . I would aprecciate more opinions before to order it: http://www.summitracing.com/parts/CCA-CL21-227-4/Thanks a lot for your help

That would be an excellent cam for your set-up...though I'd be inclined to go with a compXE 268 if I didn't have headers (you say if you do or don't). But definitely if you're running headers, go with that cam.

Nobody here tells it like it is --those XE series make a lot of noise and clatter as they all have some crazy closing ramp that makes the computer that designed them happy but they stink as street cams--WHY put up with that clatter? Oh..they say it makes more HP--yea right! One of the older Magnum cams is JUST AS GOOD in a streeter and they do make good HP for their size--I dyno Mopars all the time --have done a zillion and those cams are not all that great---call Bullit or Cam Motion or Isky or Engle and get a great cam on a GOOD core ( lot of Comps junk is China softies) or just drop a Magnum Comp in and have a great rod--XE's are hype and clattering crap as far as I am concerned

I ran 10.9s on the XE284H junker, with a best of 10.91, all this shifting at 5600, there was a 10.8 in it i'm sure, so yeah i'd say there crappy & don't make much power  , But i will say most of the lifter clatter is do to running run of the mill hyd. lifters, the magnum lifters they sell with the kit are junk IMO, clatter city after a few thrashings, So i learned my leason & went with the "pro-magnum" (anti pump-up) lifters & never looked back, there a much better design & are for high RPM, they carry a heavier C style clip & can be run at 0 preload. I'd rather hear a valvetrain have a mild solid cam like sound but know i have the added peice of mind the lifters are going to handle it & no fall apart! With such a mild 440, i'd run the XE274H & call it a day. But you can go with a custom grind like mentioned from Bullet, Isky-Racer brown exc.

Thanks a lot for the replies,that is why i always prefer to ask 1000 times before to order something.
The trouble is that now i,m very indecided,cause the noise and the clatter wich you refer to ,are not very desirable options for the kind of car i want to build.
The guy who suggested that cam to me also spoke about the Lunati voodo 60303 http://www.summitracing.com/parts/LUN-60303/
I don,t know if the trouble would be the same.
I also have heard good things about the mopar purple 509 cam
About the Magnum Comp,it would be a good option to looking for one with the same lift and duration(More or less) and also order a set of Promagnum lifters?
Thanks a lot again
Ah!The car has Hooker super-competition headers and 295/50r15 rear tires.

That cam might leave you a little low on vacuum if you run power brakes...and would be happiest with higher gears.
The 484 cam would be a good street cruiser for your set-up.
--As far as the cam noise, I've never run into a problem w/ lifter noise with such cams. I did use custom length pushrods to ensure proper pre-load.
My favorite cam I've used have been sourced from hughes. Racer brown and other mopar specific cams are likely just as good, though I've yet to try them. But Dave from Hughes has always been very helpful everytime I've called; And when comparing cam of similar size to his cams, I'm a believer. I used a similar grind cam from him compared to a MP cam I had and the power difference was more than just seat-of-the-pants difference.
If you were to check out his stuff, his HEH3237 would be a good cam for such a car (232/237 @ .050, .540/.548 lift, 110 LSA). Healthy idle to sound good at the cruise in, enough vacuum for a street car, enough power all around to satisfy.
But the reality is given your goals, there are a number of cams in the range you're looking at that would work fine. Heck, since racing is specifically NOT a goal, perhaps just going with the "big" summit cam would suit you since it's an easy cam to live with, nothing about it will stress the valvetrain or lead to undue noise, will produce enough vacuum, etc, etc, and of course, it's cheap!
And if you do want to go quick, that's just what 440's with good heads do, regardless of cam selected.

You mean "lower" gears.

Thats where adj. rockers help cure that issue.

I have sent a mail to hughes but they are taking two weeks or more for replying.
Also have filled the Lunati page "Find my cam" form with the engine specs and my intentions, and they have replied to me very quick.
They say that acordding to their calculations this should be the cam:

Also have found a thread where a member seems to be very happy with the 60304,but i don,t know what compression ratio he is running.

Call 'em...believe me, you won't be disappointed. Prompt and courteous...and very knowledgeable.
The other cam looks a touch small....not horrid though, but small for a manual trans cruiser.

looks like a decent choice. I went 12.90 in a 67 coronet with a almost 9:1 set-up like yours. I used the summit 488 cam, stock 906 heads, headers, 750DP, RPM intake, 2600 stall and 3.91's, Maybe you could use a steel shim gasket and bring up the compression some?

Well,i will try it...I say this because i,m a lost man out of the E-mails ,i,m very bad speaking English ,more by phone,but i will try it
Mr yuck,when i was using the compression calculator i was checking it with the .020 gaskets and the result was 9.31 :1 or so.
You´re right,could be another option .
Did you Dyno test that Coronet?
