It is a huge undertaking to maintain a solid lifter cam.




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.





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






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...

I would agree with what others have said reguarding adjustment. You might have to run them a couple of times at first. While everything seats in together. After that 1 a year. I would strongly recommend using the MP lash chart to adjust the valves by. I believe it is the only way to be sure. You have the lifter in the same position on the cam lobe every time. You really won't need a timing tape. Just measure the circumference of your damper. Divide by 4. The place a mark on the damper every 1/4 of the way around it. This will be 90* on the crank. Makes it easy to run the valves. Jim

Theres a lash chart in the tech archives, setting the lash is easy. Start at TDC adjust 2 valves, rotate 90 degrees adjust 2 valves and so on until your done. I don't pull the plugs, why bother, use a socket on the dampner bolt. Use the reusable valve cover gaskets. Whole process takes me about 30-40 min. I'm running a .528 solid in my 318, my first experience with a solid cam and i'll never go back to hydraulic. She pulls good right up to 6800 rpm's...

When I ran a solid with iron heads we found the intakes closed up about .002 and the exhaust about .004 so we just set cold using that info so if we wanted .028 intake we set it .030 and if we wanted .032 exhaust we set it .036.
We did however run less lash than MP said and went for .022/.026 hot

Well I might have to give the 528 a look again if there is no problems with the mp cams

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???

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.

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?

64Post mentioned about subtracting .005 from the lash when using aluminum heads. Please explain why.
