Any interest in Gen 3 Solid roller lifters?

I like the idea of a stock stroke 6.1L Hemi with a high lift cam that will spin between 7K and 8K.

Only downside is Harland Sharp adjustable roller tipped rockers are 1800.00 per set. By the time you upgrade the springs, order a custom ground cam, and buy a set of solid roller lifters your pretty near the cost of a blower that you can bolt on in an afternoon with more power.

Like I said, I like the idea of a high revving naturally aspirated motor. But the economics seem to be against it happening. One of my dream Hemis would be a stock stroke naturally aspirated hemi that put out 650HP with ITBs, as of right now, I don't see it happening, at least not on my budget. :(

B5Blue,

Resonance in the head? Little more explanation would be nice. Could this resonance be the result of a lack of decent intake manifolds? Right now manifold choices are too limited. The 6.1l Manifold seems to have too long of a runner for truly high rpm use, while the Indy Mod Man manifold and XV manifold don't seem have any development work done to them at all. I'm no expert but those manifolds seem to be full of compromises. No runner length to speak of and a plenum as big as a house. The fact that theses engines still perform well with these manifolds is a testament to excellent head design and modern carbs that must atomize the fuel really well.

If I'm wrong about the manifold, feel free to school me. ;)
