HR cam discussions in a street 455 start w/ a cam like the CCams HR288 (I'm sure other makes have cams w/ similar specs). It has 236/242/110lsa. I "think" Dude and SD make a grind that is a little spicier and you can call either of those two ( I think the Butcher special and Old Faithful are the cams respectively). I "think" those two cams were designed for street/strip work - call those guys, great reputations and will help you optimize your combo.
I've run the HR288 in a 3700lb GTO, four speed w/ 3.42 gears. I surmise that a 67 bird w/ 3.55 gears and a four speed w/ street ported heads (I've run Butler street ported heads and that cam) would be pretty sweet and driveable.
I DON'T have the experience that these other guys posting have - but my reccs would be a performer RPM intake w/ tuned built qjet or TII, 1" spacer and a holley 4150 (again - built to your specs) and at least 1 3/4 headers (1 7/8 better) and at least 3" head pipes w/ x-pipe. The four speed will be harder to get ET's faster - the lighter you can make that car, the better. Also, lighter = less broken stuff w/ a manual tranny and easier to get traction.

GTO Lou, what times did you run with the HR288 cam?
