my timing table is a guess i've never tuned for this particular cam before.

EFI and distributors can be tuned nearly the same way, just think of your RPM rows as your base timing vs your final timing, and the curve to get there. then your MAP columns are vacuum advance on top of that.

if you made a graph of timing advance at various points of a well-designed vac advance distributor setup, it'd look kinda similar to an efi timing table.

i did look at your timing table, it's a bit cracked out for sure.

think of it this way, that cam under 40kpa will always be decellerating. so all your 'vacuum advance' only comes in on decel, except for below 1600rpm under low loads, which is way out of operating range.

look how your 50-55 map row (which i'd guess is cruising range) advances the hell out of timing up to 38 degrees, and then drop s back to 32? in driving ranges, timing should never have to decrease substantially with rpm, just level off.

lets express this a different way so you can learn about timing, if this was a distributor, how would you tune initial, final, and vacuum advance?
