I am 95% decided to go with the Lunati 60305 Hyd cam in my motor.. Here is Combo.... '71 440 Block .30 over All neccesary machine work/ fully balanced Block square decked Ross 99539 pistons/ 2.065 Comp. Height New Scat Rods Lunati 60305 cam/lifters 440 Source stealth heads/Crane Ductile adjustable rockers, bushed by RAS/ Bananna groove shafts Holley SD intake Holley 850 DP 1 7/8 headers/ 3" exhaust w X pipe MP Ignition 3.91 gears Windage Tray I have gotten numerous suggestions to go with the mp.557 solid cam. Here is my dilemma. This being my 1st high performance build I have "0" experience with a solid cam. Can someone in a nutshell explain how to adjust valve lash. Is it relatively easy to do once figured out? Does motor need to be running while doing this? I don't have my FSM handy, does it go into this in there?? Chuck

Chuck I am sorry I did not get back to your PM as I am feeling much better today. As was stated you need the lifter on the cam base to adjust and I just do mine by cranking the eng and watching the valves to know where they are. Adjust them cold when you assemble it and the after it runs a bit pull the covers and adjust them again hot without the eng running. I love the .557 cam my self as it works great in my 63 and my boys Dart. You can PM me anytime as I will try to help all I can. Good luck. Ron Oh and I only adjust my valves once a year. And I drive my 63 alot in the summer.

Dead wrong.
As long as you have good adjusters you shouldnt need to adjust the valves very often.
Now if you have crap adjusters, that is another story. DAMHIK.

It is a huge undertaking to maintain a solid lifter cam. Especially if your a part time driver/streeter cruiser type. If so then go roller or hyd. Solids take time to set up and for the most part you have to inspect! I run an Ultradyne .577 solid in my 440/498 stroker. Had I built this engine I would had gone roller but the power now is tremendous and scary fast. Not many "cams" have it as solids do.. go see a few old school builders and ask away! Im stuck with what I have for now but I tell you, this cam is crazy! set up right you can get huge power...
I just don't get it,my Ultradyne solid cam has never needed any real effort,just don't assume all valve springs are the same,just because they have similar numbers doesn't mean good valvetrain life.I wouldn't put a .557 mopar in anything,unless it had shag carpet.The last Mp .557 cam was a dog when 2 other cams were run against it at the track,maybe MP ground me a dud?

Von is dead right. As I stated I drive my 63 alot and race it 3 or 4 times a year and I only adjust my valves once a year. And they are usually not out of adjustment or only out a very little bit. I just use standard ductile iron rockers. Ron

I agree you should use the 180 method since you are new to adjusting the valves.As far as the cams I prefer the Lunati.You will have a huge difference in mid range torque with the Lunati.Top end H.P. will be close between the two cams.As far as the .557 it is the only MP cam I would use if I had no other choice.Ultradyne,Engle and others have some terrific solid lifter cams.One note if you decide to run a solid invest in a set of edm (oiling) solid lifters.
Leave the gun.......take the Cannoli's....Mike

Were these cams purchased before or after the nitriding process?

if you get the understanding how they work,and adjust,you will never go back to a mudstick cam. get detailed instruction on how to adjust,and ck hot later,and GO!..and the FSM might help,but with that cam,make sure your on the "backside" of the lobes when making the adjustment...the big cam guys will explain in proper instructions .also did you have a good head guy go over the heads,or are they ready to run??? better ck .oh,just ck how many engines cam with solids..../6? sbc's by the thousands...ect ect..ya solids are scary,like the ones in my 1953 f-head jeep...

MP cams have always worked great were designed to make use of the Big mopar lifter way back in the day before anyone else thought of it. Cams designed for mopars not chevy's then cut on a mopar blank!!! But seems more today than ever degree should be checked with the tolerances of the cam dowel, cam gear dowel placement, crank gear keyway placement and so all can stack up to a cam way off and often retarded when the respond well to a little extra advance on a street or street strip motor. No cam works well degreed way off but mild cams are more forgiving?? But mild = slow in my book and who wants that???

Well I might have to give the 528 a look again if there is no problems with the mp cams
I used to run the 528 before I stepped up the convertor a few years ago (and hence the switch to the 557) and was very, very happy with the 528 in my 360. It was a torque monster with great street manners.
My brother ran a 528 in his 440, 4-speed GTX on the street with very good results too.
I might be in the minority, but I love the old Mopar camshafts. The they be old school designs, but they were specifically designed for old school Mopar engines that we're still running today. Not a Chevy designed profile cut onto a Mopar shaft.

What is the current part# for the cam and or cam and lifters?
P4120661 according to Summit
THX for the # ... I found it on the Jugs site ...along with the pricing.
What is up with some of that pricing ? .. the 590 cam is a bunch cheaper.
And keeping with the direction of this topic ... I would like to hear a "report card" on that 590 vs the 557 and 528.

Hmmmm. That is an interesting statement. Although, Id bet my life the .200 numbers on a MP .557,.590 arent in the ballpark when compared to say a Ultradyne NF Lobe.
Anybody have the .200 numbers on a .557 or .590?

This is what I measured on the MP 0.557" cam (within measurement uncertainty)
.020" 287º .050" 257º (256.5) .100" 222º .200" 165º
Fast68Plymouth posted the 0.590" cam years ago: Quote:
