If it matters, My numbers, gleaned from your chart are only slightly different.
But your numbers are hard to believe that they haven't been reversed. Cuz if you reverse them to make the intake 284 and the exhaust 292, and the lifts become 445/496, then the cam becomes fairly common.
Let's say I'm right, just for a second, then that cam, by your numbers, becomes
284/292/109.5/ 69 overlap, and a Ica of 68, would make the installed centerline to be 106 which is about 3.5* advanced.
In a true 8/1 engine, and at 600 ft elevation, the above 68* ICA, is predicted by the Wallace Calculator, to make 115 psi. cylinder pressure.
Whereas, with your numbers, an Ica of 79*, would generate just 100psi.
I checked my calcs three times so I hope they're right.
However, with your numbers, the bottom end of that combination with a P/V of just 74, it would feel like a tired slanty (P/V of 87).
Whereas at my interpretation, the P/V of 95 is starting to feel like somewhere between a slanty(87) a soft smog 318LA(114).
Also, I see your test apparatus, and am confident in your numbers. I just think that the intake and exhaust numbers somehow got flipped. I have a similar apparatus.
Grant me a moment to opinionate,
At an assumed to be 8/1 Scr, that cam is a terrible cam, for a pick-up truck.
Using your numbers,
To get the bottom end to feel like a half-decent 318, the SCr would need to be boosted to 11.5, to get the Dcr up to 8/1, and the pressure is already close to the limit at 160 psi. I highly recommend to, if your numbers are correct, to throw it away. That's my opinion.
Furthermore, in the current configuration, it would need;
a very hi stall, and
a crazy-high street gears, and
headers with a free-flowing exhaust,
just to get out of it's own way.
More money.
