Lunati 60403 with Hughes 1110 spring???

My guess would be that its not a good idea, simply because if it doesn't work then you're pulling the heads to get them machined after you've got the whole thing together.

The Lunati cams have very aggressive lobes, and there have been lots of incidents where guys have gotten into trouble trying to make something else work spring-wise with their cams.

That said; I am running those Hughes 1110 springs on my car, with a hydraulic roller cam using the Comp XE lobes. The cam has similar duration @ .050 to that Lunati cam and a lot more lift, and the springs do work up to about 6200 RPM anyway. I would tend to think that aggressive lobes on a hydraulic roller cam would be rougher on the springs than a flat tappet cam, but that's conjecture only. I have no actual facts to back it up.

You might get away with it, but I probably wouldn't try it.

Good luck,

Steve

How does the Lunati cam compare to that of a Hughes cam then?
