On the street you need to run with wider lobe seperation angles due to the restrictive exhaust system on many cars. On an open header we typically run 108 degree cams. One of the best running street engine we have ever run was a 427 with a 4.0 inch stroke crank with ported E-brock (6008 w/big valves) heads single Holley 830 DP. The cam was a Crower 16357 Duration 278 I, 284 E at .050 240 I, 243 E LCA at 114 duration Lift .530 I, and .535 E. You can read how the engine ran for Car and Driver at
www.kirkhammotorsports.com under the section of In the Press. The car has 3.31 rear gear with a CR top loader. The car would have been quicker with a WR. Our orginal car had a Holman and Moody tunnel port 427. The strocker engine would pull away from the orginal car on all but the top end. On the street the strocker engine was much more fun to drive. Hopes this helps.
