7 Heat Range Plug??? Does anyone know of a spark plug in the 7 heat range designed for the ls1, actually c5r heads, motors. Tr55 ngk has a 14mm thread size, is tapered, 5/8" wrench diameter, and .708" reach so these are the specs i'm looking for. Thanks.
P.S. It's for my 434" c5r headed 11.5 to 1 darton sleeved ls1. Projected n/a hp is around 700 fly wheel, thanks.
