    Which Plugs for my LT1?

    Stock LT1 engine, in need of the dreaded plugs/wires. Which brand plugs should I go with? Just stick with ACDelco plugs? I don't plan on keeping the car, but things could change. So which plug and wires should I go with? I'm looking for budget consciousness, not high-po stuff. Also, if this skipping isn't plugs/wires, where is the best place to get an Opti?

    I tried many different plugs on my LT1 and AC Delco seemed to work the best.

    I bought the AC's, got 4 of them in so far


    I'm having trouble with the number 7 (?) cylinder, the rear cyl. on the drivers side. I don't know how exactly to replace the wire itself, its in that clip thats mounted to the block between the block and the manifold. I can't seem to get the old wire out, and the new wire in. In a diagram I found with a google search it shows the rear wire actually being located on the OUTSIDE of the drivers side manifold, but I really don't think its supposed to go there. Any ideas?

    I changed mine twice! I got a bad set of MSD's and some turned out to not even have any continuity! I was pissed!
