Nobody said you were or weren't running vacuum advance... I just asked the question....48* is TONS...I just know what my bearings looked like when I ran 38* or more.....Chill...

didn't look like question. tell everyone what bearnings look like with to much total. buy the way we left the op.

Are you running straight alcholol with 48 degrees total timing? If not and your running gasoline did you verify the TDC marks and the timing marks on your balancer on your motor? If no to either maybe you should

Sorta what I thought too Cab....wasn't getting pissy or anything...just couldn't see how that would work with a gas motor...but...every thing is different I guess...

While you have the intake off I would start with 20 degrees in quick in the dist and 16 on the crank. I have never seen more than 38 total work on a gas BB Mopar. Fix the timing first,36 total is a good start, then the idle.

yep, gas, street car. loves 89 oct. drive it all the time and just about everywhere from san fran to grand junction co. @ 38 total falls flat @5000 rpm. open it up to 48 or more and it will pull to 6000. had it on a chassi dyno 325 hp @rw w/ 350tq. not everyone here runs just 1/4 or 1/8 mile. lot of daily drivers that are built. yes cam degreed when built, timming marks verified on crank w/ timing tape. not sure what your point is? tell everyone about the effects on the main bearnings statement.i would like to know.

Your rod bearings will be hammered, the 3 center main caps will lose their register and will metal transfer to the block, pistons will lose their ring lands, with a TRUE 48 degrees timing, like 20 at the crank and 28 in the dist. All problems I have seen with hero timing like that. 38 is the correct MAX timing for a bb mopar, no argument on that, 1/4 mile or granmas grocery getter. If the cam is in wrong 48 might work??

total timing is just that. a total of all. what kind of time frame are you talking about on the mains and the metal transfer for a street motor? this info is new to me and probably others as well. can you help us out?

I refer to total timing as the initial crank time like 16 and whats in the dist like 20, no vac. If you took a stock 440-6 with 10.5 and ran 48 degrees you would lose ring lands in one pass. Check out the bearing manufactures websites for pics of bearings with too much timing, or detonation, yellowbullet forums also have some nice pics. I am not flaming you but PLEASE do not tell anyone to run 48 degrees on a BB mopar. You might not be building a drag car but all 440-6 bbls are run wide open at some point, so timing must be in the safe zone.

When people refer to total timing they do not usually refer to what the vacuum advance has in it, as it does nothing at full throttle (because vacuum is 0). The phrase total timing usually refers to total mechanical timing, meaning your base/idle timing + whatever advance is in the distributor. You probably have 34 degrees total mechanical timing.

This is why people unplug vacuum advance when they set timing.

you are assuming that people don't figure vac adv into total because of a full throttle condition. how many street cars are driven at full throttle? i know that vac adv has nothing to do with full throttle and there are street cars that don't run vac adv because of low vac and they don't run full throttle( all in by 2500 rpm, thats not full throttle on my car) however, that does not mean that the phrase total advance does not include vac adv even if you think that is the case USUALLY. don't say that vac adv is not part of total adv timing, it is. depending if you use vac adv or not because of YOUR motor set up is up to you, rewriting what total is, is not up to you. keep it straight and don't give wrong info. apply the correct info to your specific needs. still waiting for the info on the mains and metal transfer and why that happens.

I don't believe I specified anywhere that you should run X total timing, but either way it doesn't really matter. The first rule of setting timing is to disconnect the vacuum advance. This is probably also part of why its commonly accepted to not include vacuum advance in your total advance number, in addition to the fact that the vacuum advance really doesn't matter for full throttle performance. Also, I happen to like vacuum advance on a street car because it does make it feel much stronger part throttle, so I agree with you 100 percent there. But the way you phrased it, and you can tell by the reaction of other members, sounds like you are running 48 degrees of mechanical timing. I don't THINK this is the case, this IS the case, and why you telling people to run 48 degrees of timing sounds ridiculous. And I don't know why you're telling me anything when I'm the one who knew what you were talking about.

I haven't rewritten anything, this is what is commonly accepted. That's why you are constantly hearing people say to run 34-38 total. When they say this they mean MECHANICAL ADVANCE ONLY. If EVERYONE ELSE is wrong, its probably you who is actually wrong. That is why everyone quickly seemed appalled that you're running a claimed 48 total. Surely 24ish total mechanical timing that would come from running 34-38 degrees of total advance including vacuum would cause sluggish performance.

So what do you run for total mechanical timing?

Well....the "Argument" seems to be what and what is not total advance.....I think the OP has enough proper info to continue.....we don't know how it's going to run until he gets a couple of things resolved. As long as he doesn't figure the timing out the "other" way...

Well I pulled the intake tonight and what do you know the two ports that seemed like a leak when I sprayed it were missing about 3/4 of an inch of rtv at the top of the gasket so it was sucking air through both of them so that is probably the cause of the low vaccum and the reason we would get the run on when we shut it off and could not lower the idle rpm enough. Sucks when you have an engine assembled by the machine shop only to have to rip the top of it off!
But since I have it apart I thougt I would make sure I get all the carb settings the way you guys think would be best for the combo.
I went to a 4.5 pv, the jets in it are 63's and the squirter in the center carb is a 32(this is my first six pack so still learning it over the 4 barrels I have done in the past, do the outbords have squirters? I did not see any and I would assume there are jets in the outboards too?) But what should I run for the jets to be safe but not too fat? some guys have said 70's on the jets and 33-35 on the squirters. What color springs in the secondaries? I will set the timing at 14 intial and go for 36 total. I will see how it runs and if it pings at all and move the timing up until it talks to me a little and then back it off. Should I plug the vaccum advance or run it?

Just want to get it close while it is on the bench as I don't really want to tear it apart again on the car as those fuel lines are kind of a pain to get a wrench onto as it seems like there is always a vaccum line in the way.

Progress I'd get a new metal valley pan gasket & mock it up with the paper side gaskets on both sides & see if the ports/bolt holes line up. A member here "topside" iirc sells .015" thin paper gaskets for cheap & I use Permatex spray gasket cement #99MA "high tack" the red stuff on those gaskets. If using no paper gaskets then I use a LIGHT/EVEN coat of Permatex #1 around each of the 8 port openings in the valley pan on both sides. People have installed em dry/as is with no paper or cement & had no vacuum leaks (requires flat/parallel mating surfaces. Holler how it runs as you continue tuning

Vette1986,

Sux you had a problem, but glad to see you found it!

Think of the Six Pack as an expanded vacuum secondary 4 barrel carb. The front half of a Holley 4 barrel is the center carb of a 6pak, the rear half of a Holley 4 barrel is the end carbs. End carbs have metering plates, not metering blocks (similar to small Holley 4barrels) and NO squirters. The metering plates have jets but they are not replaceable stock, they are drilled orifices in the plate (aftermarket sells plates with replaceable jets...Promax)

It idles on all 6 throttle plates.

It runs on the center carb at lower throttle openings.

Runs on all throttle plates at WOT. The end throttle plates open due to higher venturi vacuum (air moving fast through the center carb) in the center carb, the vacuum hose that Ts to all the carbs tranfers the vacuum. The vacuum must overcome the secondary springs, the firmer the spring, the later and slower the end carbs start to open.

Hope my ramblings make sense
