Hey All,
I just installed Edelbrock Performer RPM aluminum heads, comp cams push rods, aluminum adjustable (stud mounted) rockers, and an Explorer Upper and Lower intake on my otherwise stock 88 5.0L H.O.
The engine is all back together and will start, but is running REALLY bad! This was my first time ever doing head gaskets, valve adjustment, etc. but I think I have everything together correctly.
The car will start but idles very rough and wants to stall. The exhaust also smells pretty bad. I figured it was a timing problem, so I hooked up my timing light to see where I was at, only to find that my timing light is only getting a signal from 4 of my 8 plug wires.
Plug wires, plugs, cap, and rotor are all new. Dizzy and coil are original from 88.
So a couple of questions then:
1) If my Dizzy was off 180 degress, would my car even start? I'm thinking it wouldn't as it would spark when the piston is at the bottom...therefore no compression or air. If it wouldn't start, then I can just focus on ignition...if it is possible that it would start then I may have to look into my dizzy install.
2) If a coil was going bad it would still give a spark to all 8 cylinders correct? Is a symptom of a bad distributor that it only distributes spark to certain cylinders? What else would lead to lack of spark on certain cylinder but not others?
I have triple checked my plug wire connections...any thoughts are very much appreciated!
Thanks.
