Spark Plugs for supercharged v8

Depends on how much boost you are running and what fuel. Stock with some gap changes can handle most mild set-ups. I believe the NGK TR6 is the current one step colder plug which you shouldn't need anything more than that. Check the LSx forums for more info on specifics with the plugs and gaps.

Thanks, I'm going to run a 8psi pulley once I get my new transmission.

You won't need to change them for 8 psi, stock with a little less gap should be fine. You may squeeze a little more timing out of it with the one step colder ones though.

Yes, this "NGK TR6" is what was installed for max 10PSI and Maggie.

What amount of boost are you running? How's your 4l80e holding up? I just ordered a 4l65e stage IV from flt.

Shittt...if I get off my ass after work tomorrow and take the trans out so that it can be rebuild. Lol

The 80e had 150k on it to start, followed by me improperly filling it, it needs rebuilt. When the trans is back in, I'll be running 7lbs of boost. When I get the fuel system put in and the 8.8 on the rear, 20+lbs
