I believe the LT1 spark plug wires are vehicle specific, and the universal ones will not work. I got mine on ebay for a steal, because nobody local stocked anything other than the run-of-the-mill ones. Also, I don't run platinum plugs anymore because I run nitrous, however, even if you do spring for the platinum, don't expect them to last 100,000 miles like some people claim.
One more thing, if you think you're gonna do plugs and wires on an LT1 car in one day, well, you need to do a search and see how long it's taken others. Mine was 2 8 hour days, as the wires are a PITA. Alternator has to come off, and the power steering pump has to be loosened. And that's just the EASY stuff you have to do

May the genious at GM who designed the LT1 wire configuration become unemployed and be forced to drive an ice cream truck at minimum wage for the rest of his life for such bad engineering.

They are not bad in the Vette wich the LT1 was made for in '92 but a disaster for the F-body.

The quickest way to do the job is from under the car. I can do it in a few hours on mine.
remove the battery, alternator and harmonic balancer. Then unplug the 8 wires from the opti. Next, reach up from below between the starter and exhaust pipe on the passenger side. Unplug all 4 wires. Now remove the wires from the guides and get them out of there. Next go over to the drivers side and reach up to unplug all 4 wires. remove the wires from the guides and get them out.
Removing the starter will allow extra room if you need it also, if you have fat arms. Now stay under the car and start removing the spark plugs. The #2 and # 8 are the hardest IMO and you might be able to get them easier from on top.
Dont forget to use anti-seize on the new plugs after gapping them. Also coat the insides of the boots with dielectric grease.Tracy
