If you have a stock opti and coil I would stick with the .050

the plugs i got were non adjustable so i just installed them gapped at .055. it seems to be running good. one of the old plugs was cracked so i bet anything would feel better. i have to say it was easier on the LT1 than it was my old LS1 to change the plugs.

Having done both, I think I'd disagree

i've also done both and the 95 seemed a lot easier but maybe the experience from doing it on the ls1 in the past helped today on the lt and thats why i think it was easier.

I think it only took me 45 min to do cylinders 1234567. it took me 4 hours and my wifes small hands and arms to do #8. and the wires on the left bank suck to do when you have 8.5mm wires tring to get them routed through and behind the PS pump on my 97.

yeah number 8 is a PITA! i started with it so it was downhill from there. i was thinking of putting the 8.5mm wires on mine, why is it so hard to route them, are they fatter than regular wires? i had some on my 01' TA but i dnt remember........
