I have read (in other forums) that the .509 is bigger than the Lunati 60342 solid in 'real' duration.
That doesn't seem right?
I know the hydraulic does't see lash but 8-10 degrees more for the solid to match seems extreme.
Could someone please 'splain,,,,,,,,,,,,,,,,,,,,,,, please?

3.23 gears
Talk about a mismatch.
You're building a high rpm engine and dog it out with those gears.
Years ago I built a .060 over 413 with the street hemi grind cam, much milder than either of your choices, same heads but not as much compression. It ran ok with 3.23's and a stick but it kicked butt when I put 4.10's in.
You need more gear and better heads if you really want to run a .557 cam.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

YUP!
Lunati actually advised the 60341, but,,,,,,,,,,,,,,,,,,,, politically incorrect is the way I seem to fly?
Used to have the old D.C. 'Hemi grind (472/280?) it was a bit too mild for my tastes. I have a spare 4.56 center section. Never been fond of running them low gears, sure it rips but running down the road they ain't much fun.
Thanks for the reality check, I know what I need,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, but I know what I want?
Damned Tim Allen syndrome.

I ran those 4.10's all over the place, including a trip from Memphis to San Diego.
Not sure why people bag on steeper gears on the highway, put in an OD if it's a big problem and have the best of both worlds I guess.

Me thinks the .509 is more raunchy than the .557?
Yes but unless you're going to a 4.10 rear gear it doesn't really matter in your case. I don't think you'll like anything more aggressive than the .528 with your rear gear. A 2" tire diameter change won't fix that.

He's building a 446, which I assume to be a bored 440, nonetheless a larger displacement engine, especially with a longer stroke will be more forgiving of larger cams.
Point is my 60 over 413 was 20 inches smaller, same stroke, than his 446. Your 493 was 47 inches larger and what's the stroke difference?
Personally, I think his bottom end will be soggy.

I ran the 509 in my current 440 , it likes stall and gear plus compression. I started with a 4200 and 3.9 gears , ended with 5000 and 4.1 . I also tried that Lunati when I went sft , it was good but not noticeably better on the chassis dyno , though I never ran it at the track . Had a fabulous loud sound , even louder than the 509 . I also fitted the Lunati in a 510 stroker and another 440 both ran great with rump . The Lunati was great on the street . Surprisingly I also had the 509 in a 8:1 440 , but it also had the 4200 plus 3.9 gears though I also had 3.54 gears at 1 stage . I always run a 29" road tyre , 28" on the strip . The 509 also did a couple of interstate runs , 12hrs each way , no worries . With the tight lobe 509 there is no engine vacuum for brakes especially with a single plane intake .

One of my friends said it best about the 509 cam, "baddest cam at the drive in".
If you want something that really sounds tough, and is low effort and easy on parts, that's it.
But......... Anyone priced one of the 108lsa versions lately?(P4120237AE) Last I saw, the price reflected what I can only assume is FCA thinking, "we don't want to sell these anymore".
If I were to recommend an off the shelf grind that fits the same application criteria as the .528 cam, but would have a little rougher idle, I'd say the Hughes 4246.
For a real "street" cruiser though, I'd use something with less lift and smoother(slower) ramps that could be controlled with less spring. Something more like the 528, but on a tighter lsa to put a little more "pop" in the exhaust at idle. I haven't seen anything like that in a catalog, so it would likely have to be a custom.

If you left it up to me, you wouldn't get anything too wild for that build.
It would be milder than the 509 cam for sure.

There was a 284/528 cam with a 106 lobe center, it was one of their circle track cams...picked one up several years ago.
