New motor/1050 dominator won't idle

Yep, it's still rough, but I'm being told that dominators don't idle too well anyway. I'll keep tinkering with it and see if I can smooth it out a little more.

To be honest I haven't had any dealings with a dominator but I find it very hard to believe any decent carb guy can't get one to idle just as good as any other carb. IMO whoever told you that isn't much of a carb guy/tuner.

Here you go:
Gen III Hemi (5.7 based) stroked out to 414
Eagle heads that have been ported, etc.
12.5:1 Manley pistons
dual plug coil packs, Brisk plugs gapped @ .042"
Drag pak intake manifold
1050 Dominator carb
Comp cam (don't have the specs handy)
MSD 6-Hemi ignition control (no MAP sensor, just runs the timing), stock timing curve: 0-2000 RPM is 10 degrees, then it ramps up to 24 degrees @ 3000 RPM, then level up to 5000RPM, then tapers back to 20 degrees the rest of the way up.
Everything I've read so far says the gen 3 Hemis don't take much timing advance.

It's very possible they don't take as much timing as older less efficient engines but I'd bet your leaving some power and road manners on the table with a wimpy timing curve like that.

I agree, but I'm afraid to monkey with the stock curve until I find someone with a similar setup that can share a reliable curve with me.
