rhymster........you are a noob. you said so.....so there is no denying it, your a noob. there is a very high probability that you will screw up extremely badly if you try to buy something that is out of your driving/tuning abilities. it is ALWAYS advisable to start out with a simple, yet reliable engine for your skill level......ie, noobieness. myself, along with several others have more than strongly tried to steer you in the right direction, yet you don't seem to really want to listen to our advice.
myself, i've been racing r/c in the neighborhood of 20 years now.....just about as long as you have been alive. that said, i race (and win) with an OS CV. i also have a mugen mt .12 motor (and it has an OS carb on it) for other than club level races......but i club/local race with an OS CV.....does that tell you anything? i've tried most all the rest (including picco's)...and trust me, for your skill level, the OS CV is right up your ally. if all your planning to do is club race, the OS CV is moooooooore than enough power for you. it is a very reliable, yet very capable and very competitive power plant.
please take our advice........race and learn with a CV for your first racing season. then, if you still feel the need to over power your xxx-nt, then go for something more complicated than a CV.
i've seen my fare share of noobies come into the sport only to jump in way above their head/level and instantly have to have the motor with the most power, or whatever it is that they think is the cool factor du jour...only to wind up getting frustrated and quit the sport.
i'm not trying to be harsh here, or harp on you......i'm (we) are trying to give you the help that you asked for.
there is nothing more frustrating than a noobie that screams for help, then refuses to listen. so listen.
