Squeaking out of the rear pipes - yipes!

Refering to my own comment, above, restated here for convenience:

"Found that the initial timing was spot on at 10 deg adv, but the total was only 29 deg @3000. Seems the vac adv is not hooked right because hooked or blocked it makes no diff to total timing - the only way I can get 35 deg adv @3000 is to set init adv to 16 deg. It runs better now, but I can't get the idle down below 1100 rpm no matter what I do (was 800 before with init adv @10 deg)."

Well, I spoke to the Demon carb dudes and he agreed that my vacume attachments are correct as made. I really thought so. I think I am not seeing the vacume adv because it's already all in by the time it's at 1,000 rpm idle. Can anyone varify this? ... or can anyone tell me of another way to check the vac adv in the distr?

next, I tinkered with the timing and carb (I have not had alot of time because of more pressing issues), and through adj the carb I got the idle speed down to about 970, init adv with vac block or unblocked is 16, total is 33.

The engine is shuddering though and I don't even like running it ... it must be detonating and I am more and more sure that that is what the chirping is. I hope I don't bend all my valves.

My next step is to fill with 91 and add a booster to see if that helps. If it does than that's my answer and then I just have to back down the init timing. If it does not, than either the engine is already toast or I have no clue.

I do think it's tuning related though - I think that the TTIs and bigger pipes are breathing better and causing a condition that I don't know if I'm a competant enough tuner to account for.

Please, anyone who thinks they can help me out - I will be very very appreciative ... there are virtually no shops around here that work Mopars and I don't have much free time to tinker with the car. I really really like this car and would hate to let it go because I can't get it to run right. Thanks in advance.
