cam thoughts

Looking for what to expect from the new cam.Old cam was http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=671&sb=2 244 int/252exh [email protected] .520 int .540exh lift 110 lsa 106 intake center line.New cam http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=672&sb=2 252int/262exh duration @ .050 .542int .555exh lift 106 lsa and 106 intake centerline.Cams seem kinda similar.
Car will be drag race only
360 cid 10.3 compression,eddy rpm performance heads,m1 intake 750 holley,tti headers,904 trans and 9.5 converter 3.91 rear gear.28"tall tire in a 72 scamp
1st should we advance this new cam to like 102 or keep it "straight up".
What kind of power increase would you think this new cam may do over the old,more torque more hp.Old cam ran a best of 11.70 at 114 with a 727 trans and 10" converter,hoping to see 11.20's,think we have a shot??
