Dennis, it was a hydraulic roller, with .620" lift at 1.7RR.
However, the ramps were too aggressive. With 445ci, a 250° @ .050" camshaft shouldn't have been wild at all, but should have peaked at about 6200.
The advertised duration was 292°, with a 170° duration @ .200". It was a really aggressive lobe and it was lofting the valves.
For 445ci, it was really a mild cam, but I don't think my grinder took into account that SBF valves are a little heavier than others.
Cam degreed perfect....I'll give him that. Came in right at 112/112, then I installed it 2° advanced as he suggested.
Like I said, that was the first pull without any tuning. We made a couple of pulls, then gave up...I knew we were losing control of the valvetrain. It was flat on top and there was witness of valve float by looking at the tops of the valve stems.
Here was the first breath it ever took:
