Powell Machine posted a video showing a Magnum 5.9 360 camshaft regrind. He also shows a cam doctor report on this one before the grind.
Wow thanks for the heads up.Good luck ever getting a cam from that guy. Sent him a core last year, said it would be a few weeks. After 3 months we bought a isky.
I have heard the 5.2 cams are a bit bigger than the 5.9 cams
I think that is an internet myth. Mopar published service manuals for awhile that had some of the LA 360 specs and weren't correct.
Another myth is that the 5.2 had bigger valves than the 5.9, for the same reason. No Magnum ever came with a 1.88 intake valve, they all used the same head and valves.
I watched that, and he said he could get about .480" lift out of a magnum cam. Delta cams got .575" from a stock magnum core for my son's magnum.
It could be a myth, but I don't think so.
I know in 1994 the 5.2 had 220 hp at 4400 rpm and 300 ft-lbs at 3200 rpm. That same year the 5.9 had 230 hp at 4000 rpm and 330 ft-lbs at 3200 rpm. Everything else on those engines is the same (heads, intake, exhaust, etc). Based on that it seems like the 5.2 has a slightly hotter cam. Peak power RPM is higher and only 10 hp lower, which isn't really a lot when we're talking about a 42 cid difference. We need someone to send Powell a 5.2 cam for comparison!
I have never heard anyone say the 5.2 has bigger valves, but for sure that's totally false. I would agree that no Magnum ever had a 1.88 intake valve. They were 1.92.
