That's too much timing IMHO for a small block with good heads.... With the 18* stop bushing - I'd set it for 36* of total with 18* of initial.

Of course the old drag way of doing this would be to read the plug strap and see if the discoloration changes right in the center of the bend of the strap...

Todays head designs need less total timing - and todays gas also like less timing.... Of course the only real way to know what it "wants" is a dyno... and timing is far more important for performance than A/F ratios.
