MP .590 cam info UPDATE WITH RESULTS - 06/10/10 01:42 AM
I have a MP .590 cam but it came with no information as to where it should be degreed in. I know there are two versions; my part number ends with 663 (no suffix).

With 10 Sec 440!, Great Cam! It will perform just as well against the latest/newest modern design cams in most cases of similer size.
Its actual true .050 lift duration dimensions are around 271 @.050 vs the advertized 265 @.050 as measured by Dwayne Porter, Me and a few others around here.
Most users of it like it installed at around a 99*to 102* ICL if intake valve clearence allows.
Great cam , Mike

I installed it 2* advanced (from straight up) and found I had too much torque, retarded it 4* (2* from straight up) and it calmed the car down, but really didn't slow it down much.

Not sure if this helps but I believe the old Direct Connection spec called for it to be installed at 104.
BTW: My zero deck, flat piston, .030 over 440 w/915 closed chamber ported iron heads, and that cam made 565 HP @ 6200 and 520 ft/lbs @ 4900 rpm with an M1 single plane and 850HP. I installed mine at 104. My compression is 11.25:1
Don't know if this helps......but.........

Re: MP .590 cam info - 06/10/10 11:58 AM
Would this cam still be pump gas friendly (93 octane) with aluminum heads and say 11 to 1 compression? Would it be worth it to use this cam in a 493 at that point for a street/strip car?
Seems like it would not be too difficult to build a 600HP 493 with MCH Eddy RPM heads and a Holley Street Dominator and thei cam? Flat tops? Maybe? Just bench racing....

, not entirely snooping Keith. A couple of years ago you sent me a used .590 in great shape, I just had to pay the shipping. I am trying to build a combination in my mind that I can use it now. The .590 seems to be a cam that will get a 493 close to the 600HP mark with MCH stage I ported Eddy RPM's.... Or at least I am hoping.

I do have a good 9 1/2 Dynamic (currently stalls a tad over 3000 in the .090 in the hole 440 I have with a Comp 470H) and a low first gear if that helps...

The 590 will HATE the 3.23 gears. IMO, you'll need 4.10's or steeper?

You are right Kevin and thank you.
But I use 906 iron heads at 10.0 comp. Its a .030 over 440 and I have the Holley street dominator intake with an 850 dp. I also use a Dynamic 9.5 converter with 4.30's and 30" tall tires. I drive it everywhere and it turns about 3500 rpm around 65 mph. I may use the .590 in my next build as I want to build an aluminum head RB eng and shoot for the 10's still on pump gas and still a street car that I drive alot. Thanks again Kevin , Ron

Re: 383man - 06/10/10 05:06 PM
Just watching and listening(need something like this for my boat) ..... I have never run anything near a 600 lift. What kind of piston-fly-cutting would be needed on say a six pack or pop-up old-school 383 or 440 pistons ?
To the guy who asks about a 3.23 gear with this cam ... you would have as much LUCK with a 2.76 gear(my choice on lots of applications) .... your 60 footers would be HORRIBLE ... but it would pull like a freight-train on the other end !

The low gear set will help with that cam. Otherwise 3.23 gears would really slow it down.

Sorry guys, been busy with baseball and car shows(Super Summit today). I actually shot 'Kevins493' a private message the day he started this thread to give him my 590 advice. I've posted it so many times I thought you guys might be tired of hearing it.
My old 73 DartSport, now owned by 73DartSport had an 11.2 to 1 compression pump gas 451(added 50% CAM2 at the track just for safety but we may run a 20% mix next time out). 400 block and 440 crank, 440 length rods. Had ported Eddy heads, 590 cam and 1.6 rockers. I installed the cam at 104 so it was 2 degrees advanced, I didn't want to go further and lose MPH. Flat tops were around .018 in the hole iirc. It went 9.96 in good air, and with the tunnel ram and 2 750's it went 9.88 or 9.89 at 134 MPH at 3050#'s with me in it.
I ran crane ductile iron rockers for a couple years and then switched to Harland Sharps just for safety. I think iron rockers from RAS would be the way to go but I do love the Harlands.
Maintenance free streetable combo that would 60 foot at 1.36 footbraking and run high 9's through a quiet X-pipe/Magnaflow exhaust system. I loved that combo and may go back to it with my next car.
Oh, also had an 8" ATI converter and 4.30 gears with 32" tall tires.

Re: MP .590 cam info - 06/21/10 02:11 AM
I don't have pictures of the port work, but I do have a couple of the stamping which I will post later..saw your post after the motor was together and about 30 min before I put it in the car.
Ok update:
The motor is in the car, I set the valve lash cold before i put it in.. Went to fire it last night, and the bypass on the Indy pump stuck shut and it blew the filter apart. Let me tell you, I had the best lubricated driveway and engine compartment you've ever seen in your life. And not a good thing when you're breakin in a flat tappet cam. I caught it really quick, so it didn't seem to do any damage. I haven't been able to check the lash yet, so we'll know when I do that.
Went to the track today, thought I had the pump fixed. When I was warming it up, it stuck again so I whacked the throttle and it stuck the bypass open, only had 10-15 psi at idle. Dad told me to run it anyways, so I did. Best of the 3 runs was 11.37 at 119. It seems to be dead lean because it had a pop at the top of first. I didn't have time to change jets (we got there late and had stuff to do for father's day anyways), so I bumped the timing down 2* and it picked up a tenth. I think once I get the jetting right, it should be in the 11.1's or so.
Keep in mind, I'm running stock replacement (0.030 over) six pack pistons, max wedge heads, stock cross ram intake, and the converter from the 493 which is flashing at 5000 even behind this motor.

Jim I only used 110 Torco on that engine. It may have been over kill on the octane, but I wanted to be safe!
That was a pretty good combo. I have since been told that that is probably MP's best cam.
I am wondering if the std port Stage 6(wich I still run) are too small in their port volume. What do you think? Don't mean to hijack this thread. Don

I believe the MP camshafts are measured at .015
Just makes it hard for people to compare.The advertised duration at.050 isn't 265 like they say,it is 271

Just out of curiosity, what lift is the 312 duration measured at? .020? I'm wondering how the 590 compares to the Ultradyne NF [Email]298@.020[/Email], [Email]271@.050[/Email], 0.620" solid cam.
@ .020 tappet lift, I measured the duration @ 304*
The 312 duration is measured at either .015 or .006 tappet lift, cant remember right now. Or was it .012. It sure as heck wasnt @ .020. mike

The MP solids I've plotted, I found advertised specs @ .015" lift.
Duration @ .020" should be 8º less than MP advertises.
Duration @ .050" should be 33º less than @ .020"
312º @ .015"
304º @ .020"
271º @ .050"
Duration @ .020" should be 8º less than MP advertises.
Duration @ .050" should be 33º less than @ .020"
312º @ .015"
304º @ .020"
271º @ .050"

Here you go. For something that was hand-done probably about 20-30 years ago, the ports are beautiful. They were in the trunk of a 63 Dodge Max Wedge car that came out of California. I guess the owner did not want to use them since they weren't stock (plus they were milled so getting the intake to fit was a pain
)

dLi. the L is capital, but very narrow and taller than the rest (extenting below the other letters) the circle around them has a tail on the left.

Would this cam still be pump gas friendly (93 octane) with aluminum heads and say 11 to 1 compression? Would it be worth it to use this cam in a 493 at that point for a street/strip car?
Seems like it would not be too difficult to build a 600HP 493 with MCH Eddy RPM heads and a Holley Street Dominator and thei cam? Flat tops? Maybe? Just bench racing....
Michael
great combo-- i have a similar cam in a 493 / 93 gas / flat tops / rpm heads / went 10.40 so far-i know theres more in it (10.30)

I run the same combo in my Demon.Box stock eddy's 493 inch,11:1,560 racer brown with 1.6 intake.On 93 octane,3 chamber flow masters,Victor,Proform 950 and run 10.teens all day in the heat.FWIW
If you want a stout 590 cam look at the old racer brown grinds.That 590 is a monster compared to the MP cam
