At what RPM is it idling?

 

1000 rpm

 

Check for vacuum leaks, seems to idle awful high for that small cam.

 

can idle it down, no vacuum leaks.

 

The eddy RPM cam is 234/244 @ .050" on a 108 lobe sep. 14" of vac at idle in neutral is about right. That is a pretty lopey cam in a 460 due to the tight lobe sep angle.

When you say that it goes down to 5" in drive what is your idle speed in drive?

Do you have a stall converter which is necessary with this cam? 2500 minimum.

Ignition timing?
Distributor properly curved?

 

Was headed in the converter direction

 

stock dis. no cruve 2200 stall convertor. I know about needing the 2500 stall but i thought the 2200 stall would work

 

when you put it into drive idle drops to about 500

 

Converter is too tight! They recommend 2500 for a reason.

 

As Scott eluded to, that camshaft is WAY to big for any kind everyday driven vehicle.

 

Not to be disagreeable, but I daily drove my Cougar with that cam in a 460 for two summers, no problem.

 

Ok this makes sense. Now as to possible mitigation to address the problem.

A properly curved distributor with as much initial timing as the combo will tolerate and still start is the first order of business.
Having the vacuum advance dashpot hooked to manifold vacuum is second.

We can help with this. Telephone or email me for details.

 

As the PM that I just got told me, I should know better than to feed the trolls ... they're right, lol.

 

You guys are pretty harsh. The guy said "not to be disagreeable", maybe he thought the car drove fine as a daily driver and it may have. Maybe he is mistaken and had the standard performer cam, maybe the rpm. Why would the guys we like to look up to on the forum seemingly continue the argument? Am I a troll too because I have only been here for a few months? I dont think that the number of posts on a forum alone is testament to anyones level of knowledge or abilities. It's a place to discuss things relavant to our engines as if we were sitting in the same room talking together, right?

 

The definition of a TROLL on these forums is one who posts arbitrary information for the main purpose of causing some kind of confrontation.

DON'T FEED THE TROLLS ...by allowing a confrontation to happen.

 

If the idle circuit is lean the engine will get real unhappy when it is put in gear.

 

That made me think of something, if the idle speed screw is in too far and the plates have moved past the idle circuit, you can adjust the idle mix all you want and it won't do a darn thing. The plates being cracked open too far would also cause a HUGE vacuum drop if you put it in gear with a tight converter.

No one's said anything, but what about checking the initial? If there's too little initial you'd have to really crank in the idle speed adjustment and that could be causing some of the trouble. Maybe a small initial timing bump to bring up the idle speed a little. Then he could back off the idle adjustment and maybe get better control over idle mix to clean up some of the RPM drop issues (and associated vacuum drop)? Thoughts?

I am a noob around here but have noticed the knowledgeable people on this forum put up with alot of BS compared to other forums.

 

I see that too. It has to be difficult because Randy, Paul, Scott among many others are nice and I know that they like to help people all they can... so It probably gets frustrating telling people the same thing over and over again just to have nobody heed the advise. I have done it too, I'll get set on a concept that makes sense and ask about it to compare it against others' experiences. Sometimes(mostly) is ask because I am stuck... Just hate all the little comments. Guess it comes with the territory.

 

Most everybody has 0.02c to add, correct or not. A couple of days reading posts and anyone with a little common sense will catch on to who knows and the ones that think they know. Most are patient but even a saints patience wears thin sometimes, but there are people that could try the patience of Jesus himself, those are the ones we all go "DOH" and make fun of or ignore. Just my two cents.

 

Brad, check post #12. Scotty gave his opinion and I agree with you both. We need to know what curve the O.P. has now.

 

Damn, Some of you guys are just mean,we are doing the recurved distributor and stall, But I got it going pretty good now. The thing about the idle circuit is probably the best guess. I had a Moroso 1" plate under the carb and I think it was messing with it because when it was removed, the truck runs great. I had checked it for vacumm leaks a millon times and I never picked one up, so I'm thinking it must have been screwing with the idle curcuit. It runs great, we do drive it around town on a regular basis, with the a/c on. I want to thank everybody for their .02 cents worth, because it did get me going in the right direction. Again, Thanks Tony.

 

Glad you got it sorted out. Unfortunately, my .02 has gotten me relegated to troll status by the almighty 460 'gods'. Lol. Guess I'll have to sell my cars and buy a chevy.

 

It's possible that the plate under the carb had a slight machining or gasket mismatch that was hanging up on the throttle blade and keeping it open a little. I had something like that once and it about drove me nuts before I figured it out.
