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

I have two wiped Comp cams under my desk
Were these cams purchased before or after the nitriding process?
