Thats what im thinkin, I bet they are not really safe on the stockish ltx parts. Especially if they are using 5/16" rods
Hell the promags and the lifters, many people have gone up to 7500rpm on them. BUt I would NOT with those pushrods. Valve float on all that can be very bad and I wouldn't risk that **** on my engine

Mediocre parts are not gonna keep things under control enough to use the extra rpm capabilities of the 24x setup, but I'd still say its worth it for the tuneability and reliability.
My build is 25x/26x >.73x lift cam with some pretty aggressive lobes (not trying to be "secretive", I'm posting from my cell and forgot exact specs),COMP HIPPO lifters, Manton 3/8 .120 PRs, DRE 1.7 Shaftmounts, and PAC dual springs installed @1.94.
I'm hoping ~720#s open will keep things under control @ 7500+ rpms...stockish parts like thin walled pushrods won't stand a chance and the valves would be all over the place by 6500.

Shaftmounts and springs from Sikora, Lifters recommended by Llyod, Pushrods recommended to me by Wicked (I was gonna spend a lot more on Trends, he saved me some $$$!), and cam specced by Llyod. Lotsa research done and recommendations from some great people who know their ****

Alright, now that I have the comedy out of the way, can someone please seriously explain the hydraulic roller obsession for me?
To me it (trying to make a HR rev) seems almost as boneheaded as showing up to the tx mile with aired down drag radials expecting not to blow any tires. You guys don't seem quite that dumb so, what gives?
