I have a 70' camaro rs/ss 396bb, When I restored the car i placed an HEI distributer into the car, it has ran well for the last few years. But when i replaced my rocker arms I started to get problems with my ignition system. The problem is that cylinders 1,8,4 are not firing, hooked up the timing light just to see if they were firing, in which they were until i start putting gaslone into the equation. People said that part of my problem was I tightened my rockers too much, but I went in and rechecked it about 3 times. Next i replaced my cap, rotor, and plugs, to see if that would be the problem. After i still reiceved no spark to those cylinders, then i went in and changed out the module and the condenser. I still have no spark in those three cylinders and now im recieving no spark in cylinder number 6. I am now thinking it is the pick up coil. But if anyone else can think of anything please help me out.

 

you said you replaced your cap rotor and plugs. did you change the wires.? i know its sorta silly to think, but you may have some corrosion in those wires. it could be a coil also. make sure all the pick ups in the cap are ok. that little rubber can get worn out and lead to issues. check it out.

 

I did change my wires late last year before i put the car up for the winter. But I dont believe teh problem is though the wires i believe it is in the distributer somewhere.

 

Have you thought about installing an MSD ignition system? summit has a kit for the 6AL box, a blaster coil, wiring, etc. I bought the kit and it really smooths out idle, multiple sparks per cylinder.

 

I acctualy was looking at one of those the other day, The only reason why im not doing that is because Im in a money crunch right now.... I am also going to re-restore the car again next year... after im done with school. so im not trying to put alot of money into it at the moment.

 

You have a contradicting statement in your post.
You first said "cylinders 1,8,4 are not firing, hooked up the timing light just to see if they were firing, in which they were". Later you said "Next i replaced my cap, rotor, and plugs, to see if that would be the problem. After i still reiceved no spark to those cylinders.
So, do you really have spark or not?
Since your problem started after the new rockers, I think you may need to try adjusting them for a fourth time. It's easy to mess up, if you don't start at TDC #1 cylinder compression stroke.
I don't like following the procedure that most repair manuals give though. Try this way, it's better:
