Plug gap for TT427?
Getting ready to fire up my TTIX 427 LS3 in my Camaro, you guys seem to have a lot more knowledge here than the Camaro board so thought I would ask here...I am running TR6 plugs and need some input from the pros on plug gap. What do you guys think?

How much boost?
I'd probably recommend switching to a non-projected tip plug and one step colder, such as the NGK BR7EF plug.
For higher boost, I'd shoot for ~.030" for the above stated plug.

i would run the BP7EFS(essentially the "tr7") ngk plug, and gap them at .030", i insist on running these in a car at 700+ wheel horsepower and 91 pump gas... let me know if you have any questions, been down this path a lot in the last few years
