Nope. Only reason I went aluminum was because it’s my daughters car and I wanna make sure it doesn’t overheat i.e. better cooling and that it doesn’t detonate i.e. I get a nice 0.035 quench plus it removes about 50 pounds of weight. that’s the only reason I want aluminum on the other daughters Duster and it’s worked out perfectly Car can run the AC all day and 110 and run perfectly cool, doesn’t detonate with spark advance that the engine really wants. None of my cars of really ever been over probably 3500 RPM.
