Well, I have to concede to you guys. I wasn't aware of the huge controversy over the zinc reduction in oil. Although the evidence of premature cam wear isn't well documented, it is there and is from engine builders vs. the oil companies. Good enough that it gives me pause. Certainly if you have a pre-cat car you still have good options like diesel-rated or race oil. It looks like this happened around 2005-2006, which is like a year ago in oldster years. I guess I've been lucky. Maybe the fact that my engines were well broken in by that time, except the one on my stand. I'll be more selective on the oil for that one. I did poke an insult back, but really I do respect the experience of the posters here.

okay, now for the OP. Do you guys agree the best way to start is exhaust, intake, and cam? Okay. Now on the dual plane thing. You can run a dual plane, but remember if you want any top end you have to size the carb larger for a dual plane than you would for a single plane. I'l probably catch heck for that one too. Anyway, the reason I like the single plane is that, if you happen to get into a race with someone and decide to open it up, the horsepower will keep climbing, unlike the dual plane where you'll feel it flatten out. Always nice to have an edge. You just have to be watchful of the rpm's cause they'll come fast. If you decide to run a rev limiter, just remember that you can blow a muffler if you run into the limit (ask me how I know).
