You can't have both. A cam that idles rough won't make good power down low.

The 268 Comp Cam has a noticable idle and pulls pretty strong in the midrange. I've also heard the 265 DEH is good as it favors the exhaust side more.

i'd definately use a dual pattern cam with D5(1975) or later heads, they need all the help they can get on the exhaust side and that's what the DEH cams are for.

don't forget that just about any aftermarket cam will need springs and/or retainers to avoid mechanical interference
