CAM BRAND QUESTION

[1958 delivery]

Buying the 097 cam for my 283. Any difference between sealed power vs comp cam? The cam and solid lifters made by sealed power are about $100 less then from Comp cams.

 

[Don Jacks]

Sealed Power lifters are imported junk just asking for cam wipe out.I don't know if there's any difference in the grinds without seeing the cam cards but I do know that the quality of the parts is.For me,it's comp all the way.

I'd look at Crowers or Lunatis with the EDM hole.

 

[La Hot Rods]

I may have a used one if your not in a big hurry.

I'd look at Crowers or Lunatis with the EDM hole.

You're talking lifters, right? What does the EDM hole do?

 

[1958 delivery]

Go the cam covered. I had to reach way back in time and called an old super stock racer and he remined me about a cam grinder we use to use, he still does. And I called him and he'll grind a new core and have it for me next week.
Will buy the lifters from jegs or summit, waiting for edm info

 

[La Hot Rods]

It's a small hole poked in the face of the lifter. Thought is to add a little oil to the cam lobe directly.

Must be the expensive ones

 

[La Hot Rods]

If you have a cam grinder lined up ask him about them.
I have only installed one set but that car doesn't have much time on it yet.

 

[1958 delivery]

He doesn't sell lifters.
$180 for the Comp, too much for 16 lifters. Same pricing for Crowers
I'll rely on the moly cam lube and good oil

What James said, they edm a very tiny hole in the lifter face. I figured it might save me a big job later, plus they are very nice, USA made lifters as far as I know. https://www.summitracing.com/parts/cro-66900x980-16

 

[Greg Reimer]

That's fine if you do that, install the cam with the new lifters, reassemble the engine, fire it and put some drive time on it for break in, then after a satisfactory break in, that's when you replace the springs. Best to break in the cam on used springs to minimize the possibility of the cam going flat upon initial start up and run time.

I'll go with the comp $110 lifter set

EDM hole is the best development for flat tappets ever. No doubt that extends the life of lobe and lifter. Last set I bought from comp had those edm holes, had never seen em before. I thought what the hell is this??? Genius! That’s what

 

[El Rat]

EDM electoral discharge machine. I believe that Garlock owns / owned the patent.if it is the same machine it is used to remove hard “bolts” that are broken off in the end of camshafts or such.

 

[Bungy]

Are these EDM lifters available for hyd cams or are they solids only? I can only find them listed for solid applications.

 

[La Hot Rods]

I would think solid only, the little hole would make the lifter bleed off.

 

[Bungy]

Thanks, that's exactly what I was thinking.
