wtf is wrong now??
 

I don't notice it unless i'm parked. When I start to rev the engine higher and higher i begin to hear detonations or misfires? I haven't changed the timing for a while. The engine will start to climb on the rpms just fine very smooth and when it hits about 1900-2000 rpms the misfire/detonation starts. I drop the rpms and they stop move it up again and they start all over. It won't matter if I'm running 87 or 91 octane. Sometimes they get so bad that they shake the car. The timing is set at 12 degrees. With total at 38 degrees. What can this be? This is a carburated 302 by the way. Help guys!

may not help either
 

When I put on my intake I messed something up and it didn't seal right. When I ran it, it did exactly like you were saying. I took the intake off and tryed it again. I got it right and it stopped. This may not even apply to you but its something else.

When was the last time you did an ALL OUT tune-up?

I tear down my engine about twice a year last time I did was august 8th. The plugs look fine. I'm running 8.8 accel wires with the modern wide cap. Also the petronix ignition. I checked to see if the wires were ruted correctly checked out fine. Plugs are clean but I'm going to be replacing them soon for the n20. I just want to get rid of this missing before I spray. The only thing I could see that had something wrong with it was the cap and rotor. I haven't checked to see if any of the wires are arcing yet. Started to rain and didn't stop intil a few minutes ago. How do you guys recomend I check for arcing wires?

The way I find out, is to grab them while the car is running, it hurts, but it works.(maybe that what is wrong with me?!?!?!?!)How many miles on the car, my '66 needs a new timing chain and it does what u are talking about. My Bronco did it and all it was, was the cap and rotor, check this first.

Well at last sunshine! Checked out the wires no arcing. Played a little with the cap and rotor cleaned them off and tried setting the rotor a little higher. Worked to a certain degree. So I'm thinking that I should replace it and see what happens.

Well its been about 3 years since the bottom end was redone mileage wise it has 6000 miles on the engine. The timing chain and cam have half that. If you do replace the timing chain I recomend a double roller.

Replace the cap and rotor, and make sure the plug wires are not touching each other anywhere beyond the cap. If this doesn't solve it, you may have excessive carbon built up on the pistons, which can be cleaned with water. If you aren't familiar with this, email me and I'll walk you through it.

I was thinking of putting a timming chain(quite one).
