The older Ultradynes I have had showed a little less acceleration and a couple less degrees on the closing side of the ramp. We use the older profiles on the exhaust on some custom stuff.

The 704 spread out to 112 will be more cam than what a stock head needs, I think what Paul Carter said about that is correct. Power wise it will not beat the 110.

We often run 1.65s on the comparable Bullet cams I mentioned, the 1.65s give the idle more attitude too, there is a lot of thing going on, sometimes it is hard to compare this stuff.

Maybe something to keep in mind, running a bunch of compression the 110 version may want 93 octane, and that 112 spread out version may only want 91. Yes the 112 will not make as much power, but how about when you pull up to a pump and the only option is 87 octane, lol or 85. Ugh! I have several cars in the 10 + range with cast iron heads that can run on 87 octane, I have some towns that is all there is now. FWIW

Maybe just to supplement what Cliff talked about on the 60919....A while back Steve C. and I were discussing the 60919 and he called and talked to Shane at Crower. Shane looked up the master for grinding for the 60919. Shane gave a range that the master could do, the master was rated at .005” tappet, and best I can recall the range was 301-306 at .005” tappet. So, that puts it in the upper 290s at .006” tappet on the intake and matches up with the 308* on the exhaust that we have found. They seem to have more than one master for grinding it, and some of the masters are apparently different. FWIW, I think given the right combo the lazier version with big rocker arms is capable of crushing the newer version myself and a couple other have ran into, it is a bigger cam.

Jay,
Where are you setting the ICL of each of those?
