Looking for other fellow Buick’ ers who have experience or have run this cam in their nailheads!!! ?? Thanks
Here's the catalog page with descriptions. I don't know at what lifter rise the duration figures were taken at. It's not 0.050", and doesn't seem to be the industry standard 0.006"..... I have a Poston NH400 that profiled at 289.5* int/293.5* ex @ 0.006" rise, but the catalog adv duration is shown as 272*/282*. The NH400 is 220*/228* @ 0.050(measured). I suspect the NH500 has more duration that the spec table shows. The description makes it sound to be very fairly radical.
TA Performance cams for comparison. The Poston NH500 sounds like it's more like the TA 413-401 when comparing idle and converter recommendations.
