Question about 1998 Pontiac Trans
I'm making a model of a funny car that has an engine with two distributors. I like to be accurate when it comes to wiring and plumbing. I am wondering how to wire the spark plugs correctly. I am guessing there are two spark plugs per cylinder and one wire from one distributor goes to plug A of cylinder 1. and another wire from the other distributor goes to plug B of cylinder 1. and so on. If this is wrong, please let me know. Does each distributor have a coil wire and do they go to separate coils? Any spark plug wiring diagrams available for dual distributor engines? Even if it is hand drawn I'd appreciate a jpeg or pdf file of a diagram or rough drawing. Thanks, Dale
You are correct in your idea about how the plug wires are attached. If you want to duplicate control wiring you would need to obtain the wiring diagram of the brand of ignition system you want to duplicate. (MSD etc. These systems also require a small battery in order for them to operate. Wiring to distributor was far less complex when vertex type magneto distributors sere used as all that was required was a ground wire to shut them down (exactly like your lawnmower works), As far as plumbing, all systems need to meet safety standards set forth by the NHRA but aside from meeting those standards, each engine builder decides where to locate such items as primary and secondary fuel injectors etc. If you go to the NHRA website, you may be able to find a decent photo of someones engine...that may be helpful. Also check the rule book for such items as kill switch location, brake, chute release etc.
