"Streetable" is a pretty broad term. I run the biggest cams that Comp makes, and run all my engines on the street. But I would say that not everyone would consider these engines to be streetable. So, I'm not sure I can tell you what streetable is; that has to be defined by you.
To get to that horsepower level, I think you should go with the Comp VM series cams, lobe number 8592 or 8594 on both lobes, with a 114 LSA. The 8592 lobe is 292 advertised duration, 269 @ .050", and .716" lift. The 8594 is 300 degrees advertised duration, 277 @ .050", and .723" lift. Let me know if you are interested in these; I started selling SOHC cams through my business a few months ago, and can offer them at $800 per pair. Sorry for the shameless plug; after Drag Week I'll put the cam specs and prices up on the main part of my web site, and direct people who are interested there. Thanks, Jay
