Am I the only one who loves the single cam? Mine has 150k miles on it and it runs like new. I mean, the only way i know my car is on when I'm stopped is from the rpm needle. Of course, it does help that I maintain the engine with oil changes, coolant changes, sensor checks/replacement, seafoam and I keep it hella clean. I drift the hell out of it too though. Maybe I got one of the only good ones. All I have is a header, test pipe, muffler and intake. I have pulled on many dohc 240's even with full interior. If I blow my engine I'll probably go for another single cam. Good luck with whatever you do.
