Can someone please post a pic of the stock spark plug routing on a '91 305 TBI ? I want to see where the wires went from the factory so I can avoid running them anywhere particularly harmful. I'd prefer if it was an air-cleaner off shot. Thanks!

I don't have a pic, but I can give you the basic idea.....that is keep the wires as far away from heat sources as possible. Your manifold or headers (which ever you have) are the main source obviously. Heat causes resistance levels in the wires to go up which = bad.

 

after installing headers the stock plugs have to go because some are straight. i drove around for a few days with wires touching the headers because i hadnt got new wires yet. well needless to say 3 burned threw and the same time it was crazy. went to autozone and bought a set of 8mm accell superstocks and cut them to fit. works great
