Hi Guys;
My rebuilt 396 is running roughly 10.7CR and I have been running Exxon premium.. there is about 150 miles on the rebuild. The car knocks once it gets well warmed up (which does not take long). Timing is at factory spec.
I've been through the archives looking at threads which talk to octane boosting and have basically come to the conclusion that I have roughly three alternatives..
1 - Buy some Av Gas (100 LL) from my local airport (just down the road) and mix with what is in the tank already.
2 - Buy some of Jack Podell's MaxiLead
2 - Buy some Supreme 130 from Kemco
Before I do anything, I thought I would check in and see if I could find a consensus as to which option to pick....
Thanks, Joel
