im curious and confused. are those aftermarket valva covers? cause if im not mistaken thats an L98 which means your car is an early model C4 but the emblem on your valve covers is the emblem of a late model C4 that usually came with that LT1. what am i missing here?

that emblem came on the L98 valve cover... on the LT1, it is on the fuel rail cover.

As for AC-Delco wires? I had a set take a crap on me a couple of weeks ago - two plugs decided they were no longer going to hold onto the plugs. And they were only on the car for about 3 months.

I ended up getting another set of AC-Delcos, which, to be honest, didn't fit quite right, but they were a stop-gap... I purchased Taylors.

Problems solved.

I had a problem with the OE wires as well.....same thing, one of the plug terminals decided to quit holding to the plug.

I think the Taylors are good wires, but the boots they use are weak junk.

I like the TPIS wires alot.......very sturdy, much better boots, plus they look stock (dark gray).
