I don't know who he is, sounds like another good guess, but nope!

The old saying "the best place to hide something is in plain sight" comes to mind about now

Post clean up: please keep it on topic, take off topic discussion to PM or start a new thread.

Since hemis are all about breathing and the valvetrain, what are they using for the rockers, shafts and how much upgrading can they handle before you have to change them too?
Say you want a bigger cam; how much more can the crate parts handle without killing longevity?
What about swapping to a mechanical or roller?

MP billet stands, hard chromed shafts. The spec rocker is the MP stock replacement style but there have actually been several types used over time depending on availability, because of the push to clean up backorders. Lesson learned: substituting is better than waiting for parts to show up for 6 months. If you wait for parts, you're in the hole before you know it so don't wait.

IIRC Barton told me something like 80 or 100HP is a cam swap away and I don't doubt that, but the 528 is supposed to be a conservatively built, streetable MP crate motor...Not a race motor though many of them run in the 10s (never mind the guy who can do a wheelie in the driveway)....so the cam swap would be up to the end user....you couldn't (for example) order a crate motor with your choice of parts in it....

Since getting blocks/heads/rockers/rocker stands is no problem anymore, and since real race engine builders are now working with MP there's a pretty decent possibility for more radical crate motor combinations in the future, but they are strictly in the idea stage.

I've heard some important folks talking about a high compression, maybe roller lifter, maybe larger CI deal at some point in the future but AFAIK no testing of a combination like that has happened, and no program of that type exists right now.

Thanks Zippy.
I'm just dreaming at this point, but as others have said in this post, when you start swapping components, it starts getting expensive fast. I was just curious what the crate motor supports as far as simple swaps and bolt-ons before you just go ahead and have something built from parts....
A 528 is more than enough for the street, but there is always the urge to have the one that is a little hairier, little "more power" without killing street manners. The best way to do that is a roller cam. You can increase flow without upping duration. On a street/strip car, higher compression has limits, same with porting.

I have never seen a post change topics that fast

No offense to any one on this post, I made that comment regarding the nude girl stuff that came up, my post somehow escaped the mods deletion.

Yeah, I saw the nude girls too, but I wasn't about to hit the "notify moderator" button. I thought I was on YB for minute...
