not another cam question!!
No way in hell is 250@ .050 gonna sound tame even with a 114 LSA. I was thinkin more along the lines of a 112, though. It's gonna "sound mean" regardless.
Most anytime someone wants to build an engine to "sound mean" I just tune them out. Build the sumbitch to RUN MEAN and it's gonna sound like it. There's no taming a true HP engine. Even a stock 340 sounds mean.
