From what I've been reading, unless you're really tuning the engines and putting lotsa $$$ into it, it seems to me the best bet is to get a SOHC, and spend all that extra saved $$ on a good suspension (or anything else).

Although you're not "supposed" to race on streets, whenever I get edged on by someone I almost always lose them around corners... Unless you're on a track, quick pick up and not top end speed would help u out more. Nobody does 170+ on streets, and if they do I have no sympathy if they hit a pole, better that then me.
I'm not an expert on enignes I don't know a lot of the technical aspects of them... that's why I'm here.. but theres' my .02
