Have you checked to see if the coil is getting hot this can happen if the wires are on the wrong way round it will still run also do you need a capitor fitted as i had a accel coil explode for not fitting 1 because it sounds lke something is breaking down over time .

how old is the gas in the tank?

Apparantly it has a bunch of rust in it and was jacking it up.

I'd drop the tank and flush it out. Set your float level then balance the mixure screws and try it again.

The fuel is pretty clean now. There isnt anything even getting into the second filter before the carb now. I set the mixture screws at 1 1/2 turns out to get a starting point. It just shouldnt be running this bad. What do you mean on fitting the capacitor?

I have two inline fuel filters on it now so i know it isnt carb issues. I put on the new timing advance curve kit but it didnt help any. Any thoughts?

You completely replaced all the gas as mentioned above right? If it had rust in it then more than likely it had WATER in the tank too. If you replaced all the gas then see the next couple suggestions.
This new problem sounds almost like lack of vacuum or bad fuel pump. Is the pump new or old? Another problem sounds like choke sticking closed. Just a couple ideas for you to check. When you rev it does it return quickly or does it idle kind of high after you hit the gas then slowly idle down then eventually die?
Pictures always help a lot too if you could take a couple of those.

All the gas is new 93 octane, all vacuum ports are blocked off, was a new fuel pump and is staying between 6 1/2 to 7 1/2 pounds of fuel pressure. I have a gauge right before the carb. I have the choke zip tied open, no chance of it closing. It comes back down pretty quickly from revving, that part sounds normal. What parts are you wanting pics of?

**CAMAROBOY69** · 07-05-2005

That takes care of those questions. As for the pics, I was just thinking carb, engine shots. Mabey we can seee something by looking at them. Also by taking pics you can study your problem while on the computer. And the final reason. Just to see your engine.

Your doing a great job of giving us detail of your problems and that really helps a lot. We will eventually figure out whats wrong with the car.

When you took it for a drive and it ran like crap, was the engine warm 160+ degrees or still pretty cold. If it is just sitting still can you rev it right up with no problems? Im just a little confused how you say it wont run worth a damn.

Have you checked the coil?

Ok, figured out the problem, now to find the answer. Had a friend come over and we started from scratch, reset lifters, restabed the dist and redid the wires. Could not get it to stop popping. Pulled the distributer all the way out and found the gear on it almost completely smooth. Somehow the cam has eaten the dist gear like hell. He had a spare hei distributer so we stuck it in and bam, ran like a champ. We ran it for like 15 minutes and we got curious and pulled the distributer again and sure enough you could see where it was already eating into his gear pretty darn fast. So now here is my problem. A distibuter eating cam. I called lunati, comp cams, summit, everybody i could think of and all i got was a dull silence and a, i'm not really sure answer. Now i know what the problem is, but how do i fix it?

**1Bad68camaro** · 07-05-2005

here is a pic of the motor. And you will notice this was right before i put the headers on. But thats the only diff.

**Charley Lillard** · 07-05-2005

Sounds like the gear on the cam is chewed up. The only solution for that is to pull and replace the cam. Pull the dist and look down in there with a light and see if you see any damage. Did the dist just drop in or was it a tight fit ? Does it seem aligned right ?

**1Bad68camaro** · 07-05-2005

I looked at the cam gear, it looks fine. It was a brand new cam. I found out i am supposed to be running a cam button on it since it is a roller cam in a sbc. I just ordered the roller cam button and some sort of gear that it calls for thats like 35 freaking dollars. I dont know if the summit guy was telling the truth or not on the dist gear. He claims it calls for a softer metal gear, but comp cams never mentioned it when i told them it was the stock gear on a hei ignition. ?????

**1Bad68camaro** · 07-05-2005

The dist went in pretty easy, felt like it should and looked straight. was told that without a cam button they are known to move back and forth alot and do that. I dont know tho, i've never used a roller cam.

**MrQuick** · 07-05-2005

Well they say your supposed to use a bronze gear with some roller cams due to its billet steel construction. The newer Comp cams have a billet shaft but has a cast iron dist gear. I'd say replace the cam if you don't want to keep replacing the gear. Also run the oring that were supplied with the distributer...wait is it an MSD unit? Never mind HEI... I think a new bronze gear and cam button should do it.

**CAMAROBOY69** · 07-06-2005

Didnt realize he had a HEI distributor or I would have mentioned this yesterday. You mentioned you blocked off every single vacuum port on the carb. Did you run the port from the distributor to the proper location on the Carb. Or did you just block that off? Its hard to tell from the pic. If its not running to the dist, it wont advace properly and will run like crap.
I really dont think its the cam. Try to keep that as the last resort.
Can you get a pic with the air cleaner off and from both sides of the engine for us?

**1Bad68camaro** · 07-06-2005

yea, its raining here right now, as soon as it lets up i will take some. I had the vacuum advance blocked off at the moment tho.

**1Bad68camaro** · 07-08-2005

Ok, put the roller cam button in today along with a new dist gear. It was running great. Drove it about 5 miles and starting revving it up and it still doesnt act right. Tomorrow i will put the timing light on it to see where i'm at and hook the vacuum advance back up. Will see how that works. I'm kinda scared to pull the dist again and see how it looks but i guess i better.
