440source RB distributor anyone know about these?

[bigmanjbmopar]

Anyone know who actually makes the distributors that 440source is selling? I bought one cuz I wanted mech advance but I need to do some real timing tweeks and may have to get a kit for the distrib.

They say they have a "These have a performance mechanical advance curve built into them, which is easily adjustable"

Still trying to figure that one out. I set my crank gear at 4 degrees advance so now I am trying to get the initial 16-18 but can't seem to figure out how to adjust this distrib.

its these people when they go on their 3rd shift.lmao

Not sure who,s making them...I do know that 440 source sold out a few years back...they are selling off all their equipment and are getting away from selling ,blocks heads and stuff like that..A friend of mine did buy one and a year later it gave up the ghost...He went on and got a msd distb.

Pro Comp makes them. I called to get some tech advice from 440Source and they told me to call Pro Comp because that is who makes them.

 

[bigmanjbmopar]

Got a number? IS it adjustable like they say? Or IS it junk?

 

[bigmanjbmopar]

Procomp for sure some were I the neighborhood of thier pc8000 series which again supposedly needs no adjustment..but 440source says to bend the tabs on the advance under the pick up plate. Will have to check it out. Anyone got pics?

LMAO

When I bent the tabs down to lock my distributor I still had some movement in the rotor so not sure how "locked" it is. I gave up on it and went with the MSD, it may have been fine but didn't want to chance it. Evertime I do something goes wrong!!!!

 

[bigmanjbmopar]

OK, here is a follow up. The procomp distrib from 440source is the procomp pc 8007. I finally got a hold of someone at procomp. There is a spring kit you can buy for $6 plus shipping that will have heavier springs to reduce the advance. the thing comes out of the box with 29-30 degree of advance!, I guess for race set ups. The "bending of the tab" thing is not recommended. I have the springs ordered and when I get the kit installed I will report back on how it goes but the whole idea is to help get a smother idle after warmed up with a pretty stout cam which is hard enough to do but with tweaking I hope can be close. It's all part of the "dialing in" process right? lol Wish I had some racers next door lol. Anyway their distribs are not made in china! lmao at least not on the 3rd shift, 1st maybe!

Are you adding the crank gear timing into the distributor timing?

 

[bigmanjbmopar]

Yes so with the dizzy at 29-30 its out of the box at 34. Seems reaonable?? No room for adjustment that's the problem. I have not taken it to a ping mode yet with 91 oct so there may be some room but hoping to at least have some flexibility. Or I could just be a nut job. Probably so....lol

 

[Cranky]

I'm talking about the crank gear sprocket for the cam timing chain. If your balancer is set at true '0' TDC, then you read the timing marks as the amount of advance with the distributor and don't worry about where the crank cam sprocket is at. You set your ignition timing based on true TDC on the balancer....the crank cam sprocket is for the advance you set the cam at.

 

[bigmanjbmopar]

Crank gear is set at 4 degree advance or as it shows on the gear 4A this gear only had 3 choices if I remember right I went with 4A

But it sounds like you're using the 4 degrees you have dialed in on the cam for your ignition timing too? If so, you're doing it wrong. Ignition timing is separate from cam timing....

 

[bigmanjbmopar]

Then the timing from the dizzy which is 29-30 and the dampener which is at 15 would be what total?

Inside of the procomp 440source distrib.

Tired their spring kit, so far not impressed. think the original springs are tighter and give more off the line. going to change back.

 

[Cranky]

If your distributor is capable of advancing 30 degrees and you set your initial timing at 10, you'll have 40 total. You have to check it with a timing light and rev it up and see where the total comes in and where it stops advancing. Once the engine is built and the cam is set in place, the degrees it is set at is no longer in the equation.....

 

[bigmanjbmopar]

Well I think I am going to stick with the stock application that came with the procomp distrib and set the timing to around 10 like you say and see what happens, I need to rebuild this Edelbrock 800 as well for idle issues. I guess the purpose of this exercise is to get a smoother idle with out loosing anything off the line.

UPDATE:

Well we tried the kit from Procomp and guess what? it aint the right one! So back to square one. don't believe 440source when you ask were they get these they look like the ones on procomps web site but cannot be used with the ONLY kit they sell so it must be made by someone else who knows the china thing is looking like it. and there is no re curving kit the only thing we could do was like some one else mentioned and that's bend the two aluminum bar stops on either side of the weights to make the advance stop sooner than normal. I didn't take a pic of the after but the one of the original you can see the tabs see left and right ...bend those forward and up towards the center. 440source did mention this but I thought he was kidding?!

Bottom line we were able to take 15 degree's of timing out and are now at 40 total probably could do more and most likely will but I want to see how long they will last and see if they bend themselves back at all. But If I had to do it over I would not buy the distrib and I think 440source is misleading people.

I know I am beating a dead horse with this post

Just want to make sure I have all the facts from the horses mouth before I kill it and sell the meat in burritos! lol

Any got some new info from procomp some good some bad here is the response -



Jack,

That is a procomp distributor, and it does come from china. That is made after an old MSD design. Bending the tabs is the way to change the maximum mechanical advance. The spring from the advance kit should work to change the rpm at which the mech advance comes in.
