    440 engine rough idle cam

    hey,

    i am getting ready to assemble my 440 engine to put in my valiant i was just wondering what you guys thought would be the best cam?? i am looking for a cam that will give me a descent rough idle, but would also do good on the street.

    would probably be 50/50 street strip

    looking for a rough idle without major engine mods

    509s idle pretty rough, but i hear they can be a turkey without decent compression, gearing etc. but that holds for any big lumpy cam. the .484 mopar cam has a nice sounding idle too and should be better on the street on a lower compresision engine with fewer mods.

    I went with an isky 292 megacam, .505 lift, 244 duration @.050, 108 lobe center. Should be better on the street than a 509 but be lumpier and stronger than the 484.

    I've directly compared the Crane .467/.494 cam against the MP484 - the crane is quicker.

    I ran a .509 with a low comp 383 without any difficulties. Consistant 13.3's in a B body w/4 spd. Same engine now sports a .525 solid Isky running 12.6's... on regular unleaded. Yes, compression helps, but it isn't eveything. De-tune your 10:1CR to run garbage gas or build it to run on garbage gas and full tune it. Simple choice.

    I ran the 509 cam in a daily driven 440. It was fine.
    It takes a Mopar to catch a Mopar.

    Same here. Except it was a 383...

    I've run the Isky 660 solid roller on a daily driver, a .509 is no big deal...

    Speedy, I'm interested in your direct comparison of the crane and the MP 484. I am running the crane in my 400 right now. By the way, it has a little lope to the idle, but has great vacuum, and nice street manners. I was considering removing the crane and sticking in the 484, but wasn't sure how much I would gain. What combo were you running it in?

    Re: 440 engine rough idle cam

    The crane I had only pulled 10 inches at idle, so maybe not the same cam?

    I had it in my Van's 440, and after many miles, it broke right behind the #4 cam journal. No damage other than the cam broke and stopped the 2 rear cylinders from running. Very strange.

    Anyway, I upgraded to the 484, and noticed I was a little down on power everywhere.

    Re: 440 engine rough idle cam

    I'm running a Lunati solid lifter .577/.585 with lots of duration... it's lumpier than my wife's turkey gravy!! 10 inches of vacuum at idle in neutral. I consider it streetable (with a 3800 converter).

    The Crane pulled 15 inches of vacuum in gear with the dual plane intake, and 13 inches with a single plane intake. I have decided to go with the new 509 cam with 114 lobe separation, since I want more power without too much lumpiness at idle.

    Re: 440 engine rough idle cam

    I just went onto the Mopar website to see what cams they have nowadays - what a POS website!
    2005 catalog is the "new" item there (it even says so!) and the camshaft listings are, well, a bunch of part numbers with a price. No lift, no duration, it does tell me they are purple shafts though! Thanks Mopar!

    Re: 440 engine rough idle cam

    The 2007 paper catalog has all that info. I have 4 of them, everytime I go to a show around here, the Dallas Dodge guys force them on you! Last show I went to I told them that I already have 2, so they gave me two more!

    Re: 440 engine rough idle cam

    I have the .509 in my low comp 440. I like it, has a nice sound to it. I even bought some new pistons to get the comp into the 10's, but I'm not sure if I really want to go to the trouble since it runs so nice. Instant throttle response, and there is plenty of power at low rpm's. I'm sure decent compression would really wake it up, but I don't think it's the pig it's been made out to be.

    I used to use the .484 cam, there wasn't much of lope to it.

    Re: 440 engine rough idle cam

    We are running the mopar .590 solid cam with 1.6 ratio rockers with compression in the 11.1 to 1 range, we are also running 4.30 gears, so it pulls real good once it gets pass 2900 rpm.

    This cam has gotten us in to the deep 12.02 @ 112 on street tires.

    Check out my videos, we ran a 12.06 and a 12.08 back to back. Both at 112mph

    Re: 440 engine rough idle cam

    OK,i'm old and maybe im missing the point here. What excatly are we looking for? A well build easy to drive street engine that sees a few trips down the strip each year? Or do you want a loud rough running engine that shakes the car and sounds half dead?

    I certainly do not mean to be picking on anyone, but i would much perfer the easy running street engine. Unfortunley it appears as if your building the car around the camshaft.

    Re: 440 engine rough idle cam

    I pulled my last cam, a .670 solid roller with 280 degrees of duration @ .050, out of my 528 becuase it idled too smooth. Had insane power, but sounded as powerful as a UPS truck. If someone is asking for a lope I can completely understand....
