V8 cam, intake and carb swap +Random pics of 8600/1406/3731 going in...almost there!

Is that for an aftermarket dizzy or are my eyes just playing tricks on me?

That picture is as it is coming out. Stock gear on stock cam for a stock dizzy. I will be swapping the dizzy gear over to my Mallory as soon as this round of upgrades is done, that way the gears can continue to play nice together as they have for so long.

Thanks man. I dunno why but in that pic it looks so different for whatever reason. I've prolly done 4 or 5 timing sets on AMC's(slaps head), I feel like a heel.

It's on an 84 that I have only had for almost exactly one year, so there is a greater than zero chance that it's indeed not stock, I am just assuming that it is (70K miles one owner, no major work or mods). It also very well could just be the photo playing tricks, maybe the angle or something, who knows.

Have you fired it up yet? Mine is finally running pretty well after I got the timing straightened out. The cam is definitely a little lumpier at idle, I'm really liking it.

Not yet, I am away from home until next week, so it's just sitting. All I have left to do before I try to start it is add a new PCV valve (mine was the connected to the threaded fitting on the stock manifold, need one to push into the rubber grommet on the 3731) and finish the vacuum hook ups. I am going to get all new line I think so that I know they are in good shape. I'll be going down to San Antonio sometime next week, I may wanna take a look at yours and get some photos of the vacuum setup and what not if you don't mind showing it off.

"A" and "B" should be plugged if they are not going to be used. normally they are for manifold vac nipples to control emissions. so the only 4 things that are vac controlled should be heater controls, PCV, Brakes, and vac advance.


vac advance should go strait to the front of the carb on the pass side nipple

vac brake booster should go to either the big port on the front of the carb or a fitting screwed into the intake

the pcv should be hooked to a large vac source about the same as the brakes

and the heater controls can be hooked to any full manifold vac the other nipple on the front of the carb will work

[shiner2001]

shackwrrr, can't the vac brake booster go to C, the port on the rear of the carb that is plugged in the picture? It looks like that is the port that Edelbrock designates for the brakes.

I am not with the Jeep right now, but I have another line hooked up to the large port on the front/center of the carb. I can't recall off the top of my head where the other end goes, but it was also connected to the front of the stock carb, to the best of my memory. Any insight on that since you said the brake booster can go there as well?

Like I said, I am probably going to start from scratch with the vacuum stuff when I get back home. After looking at several diagrams, I think I can replumb it all somewhat correctly, haha.

Along the same lines of vacuum and emissions talk, what have people done with the hard line that runs down to the catalytic converter? I believe there is a joint where it can be detached, and then I suppose it can maybe be either welded shut (not sure off the top of my head what material it is) or crimped or plugged somehow. Thoughts or suggestions?

My vacuum setup is very limited because I have hydroboost brakes and the 208 transfer case. I think I even have the ball disconnected right now because I can't figure out why I'd even need it. I have a PCV and the vacuum going to the HEI and that's it for now. Give me a call if you're going to be in the area, I'm always down for showing off the Jeep.

[shackwrrr]

theres my setup.

the big yellow one goes to the booster
the big black one goes to the pcv
the front little yellow one goes to the distributor
the rear little yellow one you can see where it goes to the canister on the firewall.


here is a diagram for 79. since you dont have alot of your emissons that should work

Oh and are you going to use the EGR? it isnt really needed if you dont plan on smogging it. If you do want to run it you need the EGR CTO on that diagram


a bigger overall picture of your setup may help us help you a little better

edit:

oh yea disreguard the honda EGR. it acually bolts right to the stock manifold, I am using it as a block off plate. lol

I'm going to disagree with Shackwrrr as well, according to Edelbrock, the front port is PCV and the rear is brake booster. I know from my install that the vac was much stronger on the rear port than on the front and would cause the engine to die if not connected.

[Ristow]

for power brake and pcv i'd use the fittings that go on the manifold,as the factory uses,which the edelbrock intake has provisions for.

I thought I had it saved, but PM me your number again and I'll give you a shout if it looks like I'll have some extra time when I'm through there.

[Lindel]

I used the intake port, just like stock for the brakes. IIRC I used the rear port for the PCV.

[shackwrrr]

Im not saying that my way is best. Its just the way I did it because I didnt have any fittings on hand and was the easiest way at the time. If I were to re do it I would hook everything to the manifold except the dizzy
