Well It Finally Happened

A lot of detonation issues can be handled with good closed chamber heads, tight quench, and dished piston in a stroker. Additionally some of the new coatings help also. I am also running Evans waterless coolant in this engine. I have not really put it to test yet to verify it's claims, they say it can help fight detonation by preventing localized boiling in cylinder heads thus eliminating hot spots. I am very happy with my 408 so far.
