I want to go hydraulic roller cam, rougher the idle the better of course. I saw tbat Thumper is making some roller grinds that carry a nasty idle but still good perf up to 6000. Considering my setuo, anyone have any good suggestions on cam spec and valve train?

You're going to be limited to about 6000-6200 with a hydraulic roller cam, but you can still make it fun. Using the factory adjustables is do-able, but it will take a little more thought to get the correct pushrod length for preload.
Something in the 230-236 degree range would be good for you, match the lift to the heads, and a 108 LSA would give you the sound that you want. I'm not a Thumpr fan, but there are other ways of getting there.

When yiu say match the lift to my heads...what exactly do you mean? Chamber volume, comp ratio? And I thought I read somewhere on here that someone was able to go abive a .550 lift with the factory non adjustables. Was wondering what others have experienced.

As Brent said there are other ways to get there , you are gonna need to spend some money on the valve train and go adjustable for sure . And welcome to the forum and you ll get a lot of good advice these guy s .. Bud

On my 390 stroker dyno mule I ran stock Ford adjustable rockers on a .640" lift cam with no issues.

I too have ran .640-.650 lift with factory adjustables. Non-adjustables should be similar, just have to bird-dog the pushrod length.
