Thanks Guys, all great ideas.  I'm back at it this weekend...will keep you posted.

I'm assuming that you have all new fabricated fuel lines. Make sure that they are all cleaned out and that there is no debris sticking the needles open on that dominator. I'd put some good fuel filters in it and run it for a while. Then take the filters away when you run the car. Good luck.

Hi John  When you dynoed did you use the same carb or just a different pump and regulator ? It could be as simple as some dirt in the air bleeds . Some of the new race fuels leave a residue in the carb so it would be a good idea to check that . Chuck has a good point about the new fuel lines . How about float levels . fuel pressure 6 to 7 lbs . Dose your fuel pump have a by pass back to the tank ? Make sure that it is not stuck open . Are you running a crank trigger ? If so make sure your rotor is fazed correctly . The only other thing I can think of is your pick up wires . Make sure they are not backwards . Thats all I can think of . I would bet it is something very simple . Keep us posted !   

PSweeney:
what is it timed at ?  and when will it not idle, ie in neutral or in gear.  If it stalls when dropped into gear, bump the initial timing 2 degrees but ensure you still retain correct total timing.

It likes 34 degrees, it does have the 20 degrees start retard, I'm going to disable that function and try it. It's supposed to go away at >500RPM. Mallory says certain radical cam profiles affect the start retard function.  Will check trigger wiring too.
