I'm in with the hydraulic roller....any size, but for me the bigger, the better.
Even the biggest one of those isn't to much for the street with a manual trans.
I recommend the Comp Cams Hydraulic Roller Retrofit Cam .549/.544
This cam will make power from about 2500-6500. The .549/.544" lift and 242 intake and 248 exhaust duration at .050" allows for nice low end power without giving up strong pulling up top.
