440 with edlebrock carb, adjustment question...

[UH60L]

Wow, that just seems like way too much.  From all I have read online and talking to several people today at a car show, it seems like I need a wee bit more timing and a wee bit more fuel.

I might try the timing first, I hate the idea of having to tear into the carb...

I haven't changed carbs yet cuz I'm about to do a FITech fuel injection kit on it. Hopefully it will run better plus I'm more familiar with fuel injection than carbs.

Today's garbage gasoline doesn't allow us to run anything close to the timing specs of the 60's.  Also, tinkering with the Edelbrock Performer is easy, it's just the results don't manifest like they should since they have very limited tuning ability...

Holley 4150 pretty hard to beat as far as reliability and ease of adjusting. Measure manifold vacuum at idle to get the correct power valve, jet kit, screwdriver and a couple sets of squirters done deal.

I put 10,000 miles on a sbf with a holley hp 750(no choke tower/mechanical) car could sit a week 1 pump of the pedal and fired right up(electric pump) even in the cool fall hold the idle up to 1500-2000 for 10 seconds and idle on its own.

I'm definitely going with a holley on the 440.

Just a thought, are you running premium in your car?  I have been running plus so far, since getting mine started again.  Maybe next time I top it off I'll switch...

Sorry it's been a while.  Darn heater core went out on the way to a car show, fortunately I hadn't installed carpet yet. 

Ok, so we adjusted the timing to roughly 15 BTDC, and I put the accelerator pump back on the top notch, and that eliminated 99% of the stumbling/off idle issues I was having.

Every once in a while I still notice just a hint of it, but then it's gone.  I did notice that at roughly a half inch of pedal applied during a quick acceleration, I had a small amount of pinging, but it always went away.  Might need to just run premium.  I'll put some in next time.

Ooh sorry I didn't see your question.  Yes I run premium or 91 octane in my Charger; it will not behave with anything else.   You mean to say 15* of initial timing right?   How did you arrive at that number?  The recommended way is to keep adding timing until the motor starts to run rough at idle.  Regardless, you've improved things by setting the car @15*.  What's the mechanical advanced timing number and total advance number?   Are you using the vacuum advance on the distributor?
