Hey guys, I have a mild 360 big a big cam. I dont remember what size cam it is or the torque converter. I really have not ran the car in about 8 years, checked all the fluids. It idles fine around 900 or 1000 rpms then when I drop it in gear it goes down to around 600 to 500 rpms and then stalls.

I also have it timed around 15* or so.

Thanks,
Bob

timed around 15 degree or so.....intial or total or what?

big cam is going to need alot of intial timing ....plus some tweeks to the carb to keep it idling clean..

I will let Crackedback education you on the timing part....LOL

was it running before you put it away?

vacuum leak/ carb issue/ fuel pressure is where i would start

No vacuum leak, I have a Edelbrock 750 on it. I really don't know how to tune that. I think I have the adjustment screws turn out about 3 turns. I tried to mess when them and it starts to idle ruff... not sure.

Fuel pressure is good.

thanks
 
Nah he can use the search function...

What cam is it exactly. A big cam to you may not be to someone else.

I bet it's dropping timing when put in gear and if the cam is really big, bump it up to 20* initial then dial in the total number by altering the distributor.

5 psi max on fuel pressure. Is it dripping fuel in from the boosters when idling? If it's an old ede 750 1407 or 1411, IMO, it's a pile of junk.

Yes and no. It was acting up on me, I was getting raw oil out the passenger side exhaust but I used the marvel mystery oil and that took care of that and then it died. I been working on it off and on but it was just the spark plugs changed them and it started right up. It runs damn good and idles nice!!!!

thanks

I have the initial timing around 15* to 20* tried both. I am not sure about the fuel pressure. I have a clear fuel filter and I see it is full.

Thanks
 
Edelbrocks are finicky on fuel pressure.

If you turn more advance into the engine and it picks up rpm, the old initial setting was not high enough.

I think I have it about maxed out if I go anymore it starts to die out.
 
i started with a 1406, didnt like it, 1407, no good, next up was a 600 holley , it absolutely loves that carb. i have a 650 that i am going to try and then a 750 holley DP that will make its way on , then i will find out where it wants to run and what it likes
cam is a 284/480 2200 stall, 3.23 gear
 
Good luck. Until you verify the stuff I asked about, you're going to have fun, or frustration with it.
 
This may be a stupid question. I dont have timing marks on the balancer, I just have the marks on the timing cover. How would I time that to 15* to 20*. I see my timing cover goes 10 0 10. I have the timing mark below the 10 on the bottom about an 1" or so. It that right? It runs smooth.

Thanks
 
The timing mark to the TOP side of zero if on drivers side is BTDC. If you have it BELOW the zero, you're WAY MESSED UP. If your mark is on pass side, then you are in the right neighborhood.

Search hillbilly timing tape and my name for an explanation.
 
If your vacuum is dropping alot at in gear idle it's probably trying to pull more fuel and that's killing it. The fact that new plugs helped would seem to support that theory. A true vacuum reading in and out of gear would help the diagnosis, and give us a measure of how much cam you really have. If your considering changing carbs. i'm curious what intake you are running. Do you know your compression ratio? I'm biased on the subject, and not sure how much cam you have, but big, meaning 240 deg. @ .050 or more are much more managable with a Holley carb, jmo.

There is 3 notches on the balancer. One goes all the way across and the other 2 go have way across. The one I am looking at matches up with TDC. I is a Mopar Performance one.

I think the cam is .484 lift something like that. I have the edelbrock air gap intake. I think 10.5:1 or 11:1. I dont have a vacuum gauge.

Thanks

That's a great intake and you have plenty of compression. That cam should be fine with what you have once the carb is set up properly and you confirm your timing. I believe there are springs on the metering rods you can change to lean it out some at idle. I'll let the Eddy carb. guys advise you on that, but i think your close and a few minor tweeks will get you where you need to be.
 
Do you guys think if there too much tranny fluid would cause that? When I put it away 8 years ago it was full, then this year when I started it I had to add around 3 quarts. There is no tranny leak, its on a concrete floor and did not see any fluid on the concrete. I am not sure if it tried up or what....lol
 
Hey guys, I got my timing right. I have it at about 17* or 18*. Next question which direction is advancing it? I have the vacuum thing almost touching the firewall. And if I advance it the rpm goes up but my timing goes up too.
 
advancing the distributor is counterclockwise. expect the rpms to go up until it takes all it can , then it will misfire. set your timing, and then adjust your idle screw to get the rpm you want. make sure your mixture is where it needs to be before adjusting the curb idle.

people have different methods. i set the timing, tune the carb, set the idle
