8 3/4 gears

256 @.050 (if that's correct) is not that big of a cam in a stroked small block, sure it will make some noise at idle but it will be plenty streetable. Tell Jim what you want (and be sure you know what you want) and you will get the right cam.
I think pretty much we could call anything "streetable"... My 267 at 50 was streetable.. with 410 gears you just couldn't round it down into second gear and go around the corner and walk your way up off of 1500 RPM... You have to pound it down into first gear coming around the corner and step it up to about 3 Grand then basically bang second gear LOL... Then there's going to like beaches Cruise in on Wednesday night and coming out in a long line of cars that's going slower than idle and keep having to rev the engine up and slip the clutch and then when you can finally let the clutch out and kind of let it idle in first gear it's bucking and snapping and you look over at your wife and her head's whipping forward and backwards like you're going to pop her head off...
Now putting 355 gears and a 234 at 50 I can round corners and second gear and pull up off of 1500 RPMs no problem.. the idles still a little rough but it can idle...
Both cams are what I asked Ken for at Oregon camgrinding...
