"Quicker" advance curve; any benefit?

What plug is that?

NGK V-powers, they're basically stock replacement Magnum plugs.

All in by 2200 and TC stall at 2600? Timing all in any earlier does not make sense to me....???

Your altitude is lowering your effective DCR by a full point; no wonder it is detonation resistant! So there is the torque issue; it's cylinder pressures are lower than a stock 225 /6 at sea level. (And combustion temps are low too.) One you get to that high elevation, the sea level build thinking goes out the window.

That's what I thought but just figured I'd make sure and ask. I've been expecting this engine to behave like my old 360 but that had 10.5:1 compression, unported stock Magnum iron heads and a small (too small!) cam. All things considered the bottom end torque on this engine isn't as soggy as I expected it's just these 2.94 gears are giving it a hard time, I can tell it wants to rev up much quicker than it's able to due to the tall gears. I can currently hit almost 70 mph in first gear and third gear is useless for accelerating unless I'm on the freeway going 80 mph.

Also my cam was custom ground by Racer Brown specifically for 3.55 gears anyway.
