Not trying to get off the subject.But how does your motor do on pump gas any spark knock?I would think the tr6 would work good with your compression.

i use 93 pump gas and no knock.... 26-28° timing at wot

i see people are recomending the tr6´s for 11.1:1 to 12:1
but some say tr55 are fine up to 11.5:1
I love the internet
