Running locked,drop in at 0TDC or 32 BTDC?
I don't run a crate motor but should apply all the same. My engine builder marked a line at 32* on my balancer. I bring the motor to that mark on the compression stroke. Drop distributor in with rotor facing #1 cylinder. Verify time with timing light set on "0" and make sure the mark lines up with the 32* on the balancer while running. I hit mine near perfect this last time and just had to slightly move the distributor.
ADDED NOTE when setting the timing on a crate engine
when a distributor is locked we tradionally think that there is no reason to elevate the RPM any higher than what it takes to remove gear lash between distributor and camshaft.
On a crate engine that is NOT true
the RPM should be elevated to whatever point that the timing stops moving
normally you think your looking at advance----on a crate engine it is actually retarding
the reason is because of the timing chain that is used is flexing----we have seen as much as 5 degrees flex in some chains
checking the timing frequently on a new engine or a newly freshened engine is critical-----the flex in the chain will calm down after awhile but checking your timing is a good maintenance area anyway

And if you mark 0 on the balancer you would set your timing light to 32.
Do yourself a favor and don't rely on a timing light that does the advance for you. Measure from the marks on the balancer as the engine fires on number 1.Quote:

I use this timing light and just leave it on "0" advance. That good enough? one thing I did notice is that it has problems reading the RPM off the wire with the MSD. With my HEI it did not. It will read it at say 2400 and just sit there unless I unplug and plug it back in then it will give a reading and never update.Quote:

I called MSD about it. They said they don't recommend dial back or "digital" timing lights for MSD. The old Craftsman "chrome" light was the better one. They did say that you can try to use a digital one and if you can't get a good read (not bouncing around) then you will need a different light.
RPM readings might be because I didn't check the direction of the inductor. It matters apparently when reading the RPM.
