Question chevy 350 stalls

I am having a problem with my engine stalling(350 in a '78 Malibu). It runs rough at idle and will stall after running for a few minutes. It will normally stall right away when put into gear. After it stalls it always starts right up though. I have checked the timing and checked for vacuum leaks. I have to keep the idle at about 1000rpms to keep it running at idle. The plugs, wires, cap and rotor are all new. The engine is a Kragen 350 bored .080 over with about 1500 miles on it.

A quick story about how the problems started: The engine was running fine for the first 1500 miles. I took it in to have a set of headers and dual exhaust put on(had the stock manifolds and single exhaust). The garage doing the work had the wires wrapped around the steering shaft and they got ripped out of the boots when I turned. Ever since then, I can't seem to keep the engine running.

Since I have replaced all the above parts, I thought that the wires from the starter were too close to the headers, that wasn't it. The only thing I can think of is the exhaust system. There's no cat converters and the headers seem to get awefuly hot. I'm fairly new to this and I have exhausted (trying to keep a smile on) all my ideas. Advice will greatly be appreciated!

Probably a dumb question, but Are the plug wires on the correct plugs?

Check your timing.

Also check your idle screws on the carb. Sometimes when you add headers it tends to ean out the carb.

I have checked the timing, adjusted the idle and fuel mixture. Plugs should be 18436572, I believe that's what I got from another thread here. As I said, I'm a beginner, so I may be doing some things wrong. Am I way off with the exhaust idea?

Man, there`s NO dumb questions. This is what this site is for.

Bored .080 over...I did not think that was possible.

Never mind how the problem started. Because if you really new how the problem started...you would not be here right now asking questions! Laugh, I am there now with a few problems.

Check your rockers! I was just there last week. If your rockers are too tight you will stall and start right up.

Electrical?? I dis-agree. It works or it does not. I have heard a million dis-agrees with that but "realisticly speaking " most electrical problems are burnt wires.

It is not the exhaust.

I adjusted the rockers and it seemed to run a little better, but still stalled when put into gear after running about 10 minutes. I re-adjusted the timing and fuel mixture also. BTW the carb is a new Edelbrock 1406 (i think that's the right model#). I'm down to either the coil or the distributor itself. The distributor is out of the original 305 that was in it. I've attached a picture of it. It seems pretty rusty, is it possible to tell if it is bad by looking at it?

Yeah they're kinda rusty looking. Are the advance weights frozen in one position? I'd definately clean 'em up and put a light coat of Kroil or something on them. Also you mentioned the wires were pulled from their boots. It is possible you broke the center cores in those wires, which could (in theory) allow the engine to idle ok, but as you increase throttle opening the "extra" gaps in the wires could weaken your spark at the plugs, causing misfires.

Ok You should have read my "4 bone head things cars guys do" Search oh Auto-Part postings.

If you drove your car to the garage an it worked ok, then your problem is the items you mentioned.

1st replace your plug wires with new, next make sure you have installed them properly, next make sure your new headers are not burning-up other wires. Get back to us once you have completed the tasks. Latter

I replaced the coil and the ignition module in the distributor this morning and now it is running fine. Not sure which one did the trick, but it's running! Thank God, I've got to drive accross country in a week and a half.

Thanks for all the advice and Happy Holidays!
