Doesn’t really matter what it is. Once the CR is high enough you just can’t cram an assload of timing in it.

This is why so much JUNK was built in the 80’s, 90’s and even the 00’s.

High CR pump gas doesn’t tune like low compression pump gas does.
I didn't say you could cram an *** load of timing into high compression. I don't agree with the Bewy.
