Default Two serious questions, need help.

1) What do I gap my plugs at? I've been running them at .035, and that's what everyone on the LS1 boards say when running FI.

But a buddy of mine who builds FI engines swears by .028. What's correct for a blown LS1 running 8lbs?

2) What size belt do I need with a stock crank pulley and a 3.6" SC pulley? I have a Dayco PolyCog 36.0" belt right now, but I wanna make sure it's the right one before I tear into things.

Mods in sig.

Thanks. I had seen that thread a few days ago(yes, I do searches <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ), but thought maybe I was missing something.

Cool, that's what I thought. Now, If I can get #2 answered... <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
