Which plug to start with" help"
Which plug to start with" help" This is my first LS and Procharger build and i need to know which spark plug to put in it to start with. It's a 9.5 to 1 402ci with stock 243 heads. It's got a F1A that is suppose to make somewhere around 14-16psi, running 93 octane with a AIS w/meth dual nozzle setup. Stock computer. If more info is needed, let me know. I picked the engine up today and they forgot to include the cam card in the info, all i know is they said it's right under .600 lift.
Thanks
Allen

I am starting off with BR7EFS @ .027 on mine but most likely at our power levels I will go ahead and put 8's on it. They may foul out quicker, but its not like I wont be pulling plugs anyways. Plugs are cheap. motors are not.
Bob, I should of thought to ask you, as you always seem to have the answers i need. Thanks again #276. LOL How does the number system work for heat rating on them, smaller=?.
I8u4rd, I've been watching build as is somewhat similar as mine with alot more flare. Thanks for info.
