Good timing curve for msd 6012?
Have 408 stroker 678 lift cam solid roller 317 ported and polish heads 850 holley carb 411 gears 28" tall tire. Need help on a good timing curve before I take it to tuner and dyno. Want to take to track to see how I run like it is.. Also going to shoot a 150 nitrous after I get a good on motor run.

I wouldn't think the 6012 would be any different than the 6010 box as for timing...just how it gets its reading (24 Vs 58 wheels).
The sticky at the top of the page should help.

This is pretty interesting. Look at the pill curves in Figure 4 of the 6012 instructions and they are way different than the ones for the 6010 box. The 6010 box has the majority of the advance coming from the mechanical part (RPM based) with just a touch of vacuum advance while the 6012 has much less mechanical advance and beaucoup vacuum advance.

We should probably cut and paste the default timing figures for the two boxes into zone's sticky post.

As per the instructions a 6012 box will adds 20° of vacuum advance when the manifold pressure is between 0 PSI and 4 PSI. Your picture shows your MAP is reading 1.1 PSI pressure, so yeah, 18° "mechanical" plus 20° vacuum adds up to 38° total. Unless you live in Denver it looks like your motor is drawing a good 28 inches of vac at idle.
