Forged 347 with manley flat tops and TEA 59cc 706 heads & a LG G6X3 cam. Should I start with a 7 or 8 heat range (non projected tip) on a 100 shot and what's a good gap to start with? Appreciate any info, see a lot of conflicting info. I've read all the writeups up top but thought hearing from experience might be good. I have a feeling the 7 heat range is probably the ticket.

What's your compression? I'm running a forged 370 with 11.5:1 compression, and BR7's with a 100 shot

Should be in the 11.8-12.0:1 range.

Unless you will be spraying it a lot I think the 7's should work fine

I'll be spraying it plenty, just trying to find a starting point on the small shot for now and gradually work my way up. I have 7, 8 & 9 heat range to play with for now.

I still think the 7's will be fine. I'm around 450 rwhp n/a, and 550 rwhp on the 100 shot, and this plug works great at that level

^^I agree with starting with the BR7EF @ .032 and learn to read plugs for final jetting.
