Anyone use Lunati mechanical flat 30200740?

The Comp cam in it now is installed at 104
Advanced 2* (from 106 suggested. )
Cranking compression is 175 average
I know that probably has a lot to do with pinging on 91 and only able to put 30* total timing.
I could try retarding it at 108*
Just not real crazy about that cam.
That's why if I'm in that deep might as well replace it.
It's a driver I know the converter is tighter then most would run.
Maybe Solid flat is not the way to go.
I've had a few bad sets of hydraulic lifters within the last couple years is why I was thinking of going Solid.
The main reason for wanting to change cams is the noise. (Comp. XE.)
I've had mechanical cams that were quieter..

I can understand about that cam,unfortunately all hydraulic cams make noise now including the high end stuff in my experience. I will say the cranking compression seems a bit low for a true 10.5 compression and that smallish cam but if anything that would be a positive as far as detonation. I am with Yr on really focusing on the tune even if you decide to go solid,seems to me there is something going on. One thing often overlooked is the carb,everybody focuses on ignition and compression/timing events and a carb can have a big effect.
