You even admitted that your recommendation for a runs hot w the ac on complaint is to degree the camshaft .... Can you come up with even one piece of information that comes form the world of automotive tradecraft supporting the ridiculousness you cant stop repeating ???

I don't know it all, and had you been around for the last 9 years you would know that I don't have a problem admitting when I'm wrong. You however don't seem to have that ability as evidenced by the fact that your sticking to an absurd thesis without any supporting information what so ever, even though it doesn't make any sense at all.

Guy says there was 4 degrees positive timing added into the cam.. I am saying a factory speed density fuel injection system is not going to tolerate that, and even if he has mass air, which I don't think came on the 1986, it's still going to throw off all the pre-programed software and try and compensate for that 4 degrees.
So give it up, I'll still accept your admission that you could be wrong, because how many times do you want him to tell us he has been thru the cooling system?

I don't know if the advanced cam is causing more heat, but if you are happy with the way it runs I would leave it as is and find a way to remove the heat. I used to hate being stuck in traffic and watching the heat gauge slowly climb. I solved the problem by installing a Dewitts radiator and a junkyard Taurus fan with a DDC controller. It adjusts the fan speed to control temperature. Now on a 100 degree day sitting in traffic with the A/C on my temperature gauge never gets over 190. My motor is a zz430 clone with 10.76 CR with an LT4 intake.

No, this is simply a stupid pissing match. The two of you need to have a glass of Ovaltine and play nice.

So load up the parts cannon with a new fan and lets see!
For all we know the cam could be set up at zero! OP claims he hasn't really a clue.

This entire thread is like quicksand for you. You just keep struggling and the more you struggle the deeper you sink. Sort of like when you thought TDC changes with cam timing, like you stated back in post 8. By the way, I couldn't help but notice that you failed to provide even one single data point supporting your theory.

If you read post 55 then why would you say the above ??

I'm not struggling with anything and I've already explained how the relationship in cam timing and TDC changes when you advance or retard it.
Let me ask you this Amotox.... What is the "TITLE" of this thread?
Have a nice day!

Eh... When I put together an engine I know what the timing is set at.

Just for fun lets try one more simple one. How could advanced cam timing cause a hot running condition only when the ac is turned on ?? Your customer has clearly stated that the hot running condition is only present when the ac is on. How is this possible ??? Do you think the cam advances even further when the ac is on ???

LoL... That's pretty funny!
But the system will increase the idle to compensate for compressor load. If he is running @ 800 RPM now with unknown timing, who really knows!
So far you ask a lot of questions and never have any answers. You remind me of a green-horn.
And if OP didn't really think deep down that Cam Timing could be responsible then why would he name the thread "Cam Timing"?
Because someone he sought out for help suggested getting the timing in order as a 1st order of business? Sounds like good advice to me! But what do I know, I'm just a mechanic..

LOL ... sellc you are so far off on this I actually feel kind of bad for you. Make sure on tuesday you check with some of your co-workers on this issue, or at least do some due dilligence on this matter. Your making a fool out of yourself and you don't even know it. There is a veratiable avalanche of evidence to the contrary of your thesis. At the minimum you should be able to explain in a coherent manner why you think what you think. So far you have been unable to do that. The reason is because what your saying is total nonsense, which is always impossible to explain. I read some of your other posts and you seem like your capable of understanding this issue as it relates to timing, but until you check your ego, your not going to get it. You seriously might as well be walking around wearing a clown suit, what your saying is really that absurd.
The most telling post is when SELLC suggests I'd install the distributor, set timing, THEN advance the cam 4-degrees in the timing set. That's absurd.
You don't know 89 runs on MAF, that a MAP isn't relevant, OR how timing works in the setup we are talking about.
I regret trying to offer a second chance. I agree it's time for this NONSENSE to stop. SELLC, you may be a master mechanic somewhere, but I reiterate I'd never bring my car to you...or read your advice again.

Like I said, We do PRECISION GUESSWORK based on vague assumptions and unreliable data of dubious accuracy provided by persons of questionable intellectual capacity. Now what can we fix for you today?
That said, I have given you more of my time than you deserve. Good luck kid!

Are you going to produce any data point supporting your hypothesis regardless of ac status ??

So basically, you are the one with the problem. I'm not the one asking for help in this thread. When I ask people for pointers as a matter of courtesy I "thank" them even if I don't care for their response. You know why? Because it's the proper thing to do.
You on the other hand, just overheated! Have a good night!
