Cam overlap

My HE 3038AL Hughes cam has 13.5*@.050.
It specs at 230/237/110, and
276/286/110 advertised, is 61*overlap@ .008 for these AL cams
This is a modest intensity cam:
going from 276 to 230in = 46* on the intake side and
from 237 to 286= 49* on the exhaust.
This cam makes good power in my 367 streeter; and reasonable torque, but sucks gas compared to the next smaller Hughes, that I previously had.

The HE2430AL at 224/230/110 has just 7* overlap at 050, and
270/276/110 that generates 53*overlap @.008 tappet
I really loved this cam and was very sad when it dropped lobes. Mega torque and power at 11.3 Scr, and fabulous fuel-economy with a double-overdrive, geared to 65=1600/ 85=2100.


BTW
with only an overlap number, it is impossible to accurately determine the "size" of the cam; other than 12* is a "good size" or "reasonable size", for a streeter with a "good" or "reasonable" amount of cylinder pressure, with a well-chosen stall and gears. But
if not matched, could just as easily be a gas-sucking lazy pig.
