Oh, why hello friends!
So, I thought IADR/IanR had a cam chart for the OHC that mentioned the Volvo cams and some aftermarket cams and their durations at whatever duration they were listed at, but I can only find his OHV info right now(1800philes.com and
http://www.brickboard.com/RWD/volvo/129 ... y_cam.html). I finally came across this thread though, and good find it is.
Cool thread and awesome work, Matt!
As Jonathan mentioned to you, his cams are measured at .020"/0.5mm, as are ENEM's advertised durations(not .040"). I don't know that I ever specifically asked Janne that, but it was positioned as such in whatever OHC valve chart that I've seen previously by IanR.
Here's the link to my gallery with all of my dyno charts in it. Not everything is directly comparable because there are ~4 different dynos used at various times, one of the dynojet dynos(with the B cam, specifically) that I suspected was reading low and costing ~20hp(confirmed later when a dragging brake was repaired). Then there's the variances in chip tuning(both ignition and AFRs, not all dyno charts have AFR info), cam timing, and of course the higher charts are after headwork/header/m47 swap, etc.

It really needs a larger camshaft to make the most of things, if I really want to make a lot of power. It will also need a larger header and I will eventually get around to modifying a b21F manifold for it's individual, longer(350mm, if I remember correctly, proper for 6500rpm hp peak), larger(flow enough for 240hp) runners. I may have a larger plenum built for the proper volume.
EDIT: Here is another company that I've spoken with recently about a possible camshaft. Their website shows the durations at various measurements, which I appreciated. There aren't any mentions of LSA though...
