Injuneer-So what you think i should do about the stalling issue? Do i take it to a mehanic?

Also CrashBurn-Where did you get your comp cam at??

 

If you or one of your buddies cant figure out the stalling issue take it somewhere. Most people have a mechanic who they always go to, they establish a relationship, trust, etc. It sounds like you need to find someone.

comp cams are available from most performance part companies. They are one of the big racing companies (holley, moroso, edelbrock). So any of the supporting vendors should carry them.
But a few posts back to said something about having you heads clean, checked, etc. If your going to bother to swap out the cam I would at least spend 500 on the headsin basic porting somewhere local.

They are holding you back so much because a 383 is going to move more air. So its also going to require more air which its not getting.
SO if a cam swap is in order check out Llyod Elliot. He has heads and cam packages for all types and levels. The Le1 heads and cam would still be a little small for your 383 but would be a hell of alot better than the stock head/hotcam combo you have now.

Really what you would want would be le2's or another head with similar to it. Also the le2 cam to go along with it. With them you would be or potentailly getting all you could from your motor.

I was new around here once too, be careful about how and what you ask. The title of you thread has a lot to do with it too. My boss always says "everything is free if you know how to ask for it". It goes the same for this site. All the knowledge in the world is at your finger tips, you just have to know how to ask for it. good luck

 

I 100% agree with the above, but if he is running 12.9, the car has to be running at least half decent(although that may not be good for a 383 with hotcam). Does anyone here have any reference runs with a somewhat similar setup?

I would suppose that since a 350 with a CC503(and the right supporting mods) can go 12.0 -12.5, then his current state of tune is in question.

It honestly sounds a little like my situation, but what is killing him is the 383, stock heads, and hotcam. We just don't know how that combo is supposed to run.....If he doesn't know much about cars, he better take it to someone who knows their ****.

What I mean by that is....some mechanics are not smart enough to tell you what is wrong with the car unless the computer point blank tells them.....this will be more complicated on a "non-stock" machine. If you do take it to a mechanic, be sure he/she is good.

 

^Thanks for guys input. Yea well theres a place for me who does porting but theyre charging 1k for porting and 400 for cleaning and valve cleaning. First thing i need is a good cam but can i just get a cam and swap it out with a comp cam? Or do i need supporting parts for it? I already have roller rockers. And i cant find any cc503 cam anywhere. I went to Avanced Inductioncans and cant find it. Any help would be useful.

 

I think Injuneer is trying to tell you to make sure that the motor is running right before making performance changes....

I agree with that and am doing the same thing myself. Right now due to my low trap speeds, I know something is not right with mine...and I'm trying to correct that with the tune up I'm doing....I certainly want to start my performance upgrade on a good running engine. Doing otherwise will just cause headaches.

Is your car stalling/stumbling? You mentioned above it was slow....Injuneer said you posted somewhere about it stalling....

Now, if your doing heads too...you need something else besides the CC503. I not sure what you need for a 383. Do a search in this forum for 383 cam. That should yield some help.

 

^ I mean the stalling is not as bad as it seems. It has only stalled twice and thats when im just letting the car drive by itself and not adding any gas in a parking lot for an example. Also, the car is not slow-slow, its seem it could get more power with the set up i have. Thats why i need a cam. Im thinking of doing the head and valve cleaning in a few months but i need to get my cam first. So ACE and everyone else, you think those cams you mentioned will be a good buy for my car? And do i need any supporting mods to go with it?

 

Head and valve cleaning isn't going to help. Take it to a mechanic and he will probably tell you its not a 383.

 

^How do you know its not a 383? Why are you so negative huh? Were having a positive discussion and you come and say its not a 383.

 

How do you KNOW it is a 383? Without pulling the heads and the oil-pan and taking measurements; or having the receipt of the work done you're just taking someone's word for it, and people lie.

 

Because I've read all your posts, and thats EXACTLY what it looks like. I'm not talking about just this thread, all the others you have. It doesn't have power....it stalls...how do I know if its a 383....

Leme ask you one question: Have you confirmed ANY of the mods on that car? Specificly the gears? Sounds like someone dumped their problem on you. (your not the first, It happened to me too)

 

^ Ok thats true. but the thing is i like to think positive. Im going to get thing checked out by a high performance specialist and if its not im going file a small claim.

 

Guys, he's already took it to the track and ran a 12.9 with it. If you think he's going to do that in a stock auto.....

 

^ So ACE, if i just want to do a cam only and just refurbish the heads in a couple months, would i just need a cc503 like the ones you mentioned or do i need other supporting things? I already have roller rockers. Anything else?

EDIT: Im going to search the forum right now to see if i need anything else.

 

If you're going to do the heads, I'd have Loyd Elliot (LE; search) do it and put a package together. He will clean up and port the heads, and "match" a camshaft with the heads. If you've already got roller rockers, then you shouldn't need anything else besides install supplies (gaskets/etc)
