The listing makes no mention of what advance head is in the unit.
And Summit's customer service couldn't tell me.

The guy called tech support, but hey were busy. Said they would email me the information. But who knows when that will be.

Like Shawn said...you'll get to mess with new one too...

Not sure there is a standard on what comes in the heads of these dizzies...it's a crap shoot. Plug, play, time, curve and recurve to what YOUR engine needs...seems there is no one size fits all...

I've thought about your curve a bit and to be honest, Vince, I'm not sure you'll gain much to write home about. Assuming your numbers are correct, the only reason you're able to get away with that aggressive curve is because of your automatic. Lowering it will likely do nothing more than take away some of your throttle response while it's in gear.

The 32* at the top end *may* show an improvement if increased a couple of degrees but I don't really see it being worth your time.

If this is something you're wanting to tackle this winter, I'd seriously look into the Stealth HEI mod and use an aftermarket module from either MSD or Performance Distributors along with ditching the resistor wire and running full battery voltage to an aftermarket, e-core coil or equivalent.

As much as I'm usually on board for a curve change, I'm not sure that I see it being worth your while.

Just my two cents...

I'd find a junkyard dizzy with the right advance weights on it.

I see your point and, honestly sort of felt the same way. But didn't want to let you guys down.

You just saved me 50 bucks.

I may do the HEI down the road. But considering I haven't driven thins thing in months I wouldn't mind running it the way it is for a while.

As with any other CJ, there is still plenty to do on it.
(Like figure out what the knock is and if it's worth worrying about)

Thank you all for the help on this.

Sorry Shawn....

Let me clarify:
Last time I took it out for a test drive there was no IGNITION RELATED knock/ ping/ whatever....

There has been a knock in the bottom end since I installed it after getting it from BigJoe.

Wheel, Fix, repeatů.

We don't have to end this. If I may. I am in the almost same position and apparently only got half way there. I am willing to change my springs and produce a curve on a t18 and that way futur searches can decide which is best for them

Temps here will only be in the 20's today. So I doubt I will be putting the things back together tonight.

The only heat I have in the garage is a propane salamander, so the fumes and lack of being able to hear the radio over the 'jet engine' makes it seem like a bit of a PITA to deal with, just to reassemble the dizzy.

I'll put it on hold till the temps are in the 30's and I have more to do.

You can always find excuses, it's solutions that take a little effort.

Bring the damn dizzy indoors and put it back together. Should take about 5 minutes.
