Hydraulic roller cam

It looks like i have to replace my comp cams retro roller 34-432-9. The distributor drive is buggered up. Anyway i found the cam very noisy, i even removed my aluminum valve cover because of the valve train noise, they echoed. Since im replacing it, any suggestions on what cam i should look at that will still work with my lifters and pushrods. It a 501 scat stroker with srp dished pistons with about 9.7-1 comp. ported dove heads, headers, performer rpm air gap and a sniper efi.

Use a solid roller lifter & cam or a good flat tappet grind.

I am wanting to keep cost down and reuse my lifters, springs and hopefully pushrods. Im leaning toward a voodoo hyd roller and see if it quieter. Not sure if a crane or howard would be any different? Live and learn, i should have went solid roller but compcams talked me into the hyd.

OH ... they are Comp Cams hydraulic roller lifters.
Now I understand your plight; good luck, the noise problem is probably not the camshaft.

Are you saying its the lifters that are crap?

Sure sounds like the voice of experience to me.

So are they defective or are they useable just noisy

The ones I have tried to use are usually noisy like a regular " high rate leak down lifter" is, when running.

Well i guess i bought the marketing. They calm lowest leakdown rate but i guess compared to what. Well ill try this voodoo cam, hoping pushrods will still work and see what happens this weekend. So much money for a set up i was hoping would be more reliable with todays oils.
