197@.200 would be huge for a lobe that’s 267@.050. It would still be quite big for a lobe that’s 273@.050.

Might be close to a HXL lobe. Lobe 2233 is 303 advertised, 274@050 and 197@200 with 454 lobe lift.
The Kaase lobe seems to be a little more aggressive than most of the lobes I could find in the Comp lobe family book. Maybe Kaase is taking advantage of the larger cam journal size that the big Fords have?

Let me quantify my previous statement……… It seems like a pretty quick lobe for a combo using large steel valves, 1.75 rockers, and springs that are only 600lbs open. I’m not going to second guess Kaase, so the proof of concept will be told on the dyno. That being said, I don’t feel like the cam(from what we can tell thus far) and the springs/RR are that well matched. If after a couple of hundred trouble free 1/4 mile passes, and the springs still test good afterward……..then it can be said the combo is well sorted out.

Looking good. It is hard to believe what SBC's (and Mopar and Ford) are making recently. There are a handful of SBC builds that have crested 800hp even with 23 degree heads and cast single carb intakes. Some of the best 23 degree stuff is done by Chad Speier. Those flow over 350. When you step up to some of the more recent head designs and improved valve angles, the hp goes up rapidly from there. I love seeing what Guys like Brett, Chad, Bob Book, M@M, Uratchko, etc make for power. It's a whole different level. I agree. A friend runs a gen3 392 hemi, dynos 775 hp with stock class rules heads, stock valvetrain parts,save for cam and springs i believe. Car runs the numbers to back that up.

Andy, what did the RR work out to be with the full spring load? Rocker arm ratio appears to be good. Getting about 0.790 lift with everything bolted up and ready to go. Lash is 0.018 on the exhaust.

You're probably right, the variation and listed values probably differ because of various lifter wheel diameters. The HXL lobes have a good reputation with a few people I know.

Not that it'd matter to anyone but I am consistent with this opinion/well said.

So that’s .790 net lift after lash?
Or, .790 lift at zero lash?
If it’s after lash, the RR is higher than 1.75
You must be getting close to making some noise.

Sitting on the stand waiting to run on the dyno. I had to fabricate some parts for the vacuum pump system so that took some time. But now it is ready to go, just waiting for a hole in the schedule.
