SBC plug indexing

Bob Miller · 03-10-2009, 11:22 AM

I am running Stock class and want to get the best out of my plugs. I have heard different theories on proper indexing, can anyone help with postioning the electrodes to the right direction in a Small Block Chevy for Stock Eliminator motors for a better flame travel? Thanks

Somebody will post a link because I can't find it now. But there is a member here that offers an angle plug adapter for a straight plug head via an insert and a small 10mm spark plug. Well worth the money in my opinion.

I looked for something on these adapters and couldnt find anything more, any help would be greatly appreciated. I really am just looking for someone to help me. Do I poit the gap toward intake, exhaust, or center of combustion chamber. Just wanting to try to see if I get a better burn and extend plug life.
Thanks again.

Conway Witten is th man to pm about the adapters, but he will refer you to Chris Cogan @kaizen motorsports. the phone number is 419 576 7138, the adapters are about $275 and they come with a bunch of shims to aim the electrode. I have a set coming and Chris was real helpful on the phone, they have some impressive gains with these pieces.
