Are talking about the LT1 or the 3.8? The first time changing spark plugs in the LT1 was a PITA but I soon learned it can be done much quicker and with less headaches from underneath the car. I'd think since the V6 is front to back and not sideways it'd be pretty easy from top or bottom.

 

If you can bend yourself into a human pretzel, then yeah, they're easy-peasy lemon squeezey.

 

only difference is 2 less plugs to do. lol. still tight quarters.

 

Torque hit it right on the head, if it's stock I usually go OEM, makes it simple, if not then it's time to match everything together

 

Bosch and msd or bosch wires witch cost less.
They work for Jimmie Johnson.

 

No one really likes Jimmie Johnson.

 

I have both. I consider LT1 #2 plug the toughest, JMHO...
2 less plugs, aye. The ACs I took out werent too badly worn, and I suppose they were copper because she runs great with the NGK plats I put in but maybe a tad less throttle response.

Pulling the starter made 4-8 much easier, but I rounded off the passenger O2. Ran car to get her hot, but buy the time the pipes cooled for me to pull starter, O2 was cool... If i pass MD smog, Ill wait til it throws a code.
