And I'll wait on nitrous until I make a full n/a pass and this big block wakes up.

Switch is ground I think as arm of pedal touches it at full throttle so I'll just pull wire and wire together

Didn't seem to do anything? Advances timing the same tried going to 2 and 3 grand apart or wired together and no differences. It really missed 2nd to 3rd do you think it's only set up to work there for nitrous?

Disconnect the pink wire going to the retard box. Set the dial to zero. Check timing with timing light and set it with the distributor were you like and make a pass.

What was it showing for total timing ? Turn on all switches the same as you had them at the track, and if it is triggered then Yes turning it to zero should put 14^ timing back in you should be able to tell the difference from what you just did.

Yes black tape both ends of the wire. This will eliminate any retard until you can get the wiring and switch's figured out, and you can set your timing with a light the old school way and rule out the electronic's as the problem, which it might not be anyway.

What Falcon was getting at, I believe with the switch's, is that there should be a separate switch to arm the nitrous, and the retard is fed by it also.

I'll bring timing light with but cutting the pink should solve it if it's the issue?

Yes according to MSD's schematic it should eliminate any retard signal.

What heads and what compression?

Start around 32 degrees and make SURE you are at top dead center with the timing mark at zero.

Okay someone step me thru the timing please so I don't miss any steps and mess this up(geez too long since I've done this ). What rpm do I rev to right now to see what their timing was set at? They have a mark close to 40 on pulley.

That depends on the springs in the distributor. Seems how you have no idea you need to start with the timing at idle then slowly rev it up to see where it stops and at what rpm it stops, You want to do this with no vacuum advance or any other timing controls. Typically you would have all the advance in around 3000 rpm but that will depend on the build. You need to figure out your baseline then go from there.
