340 cam selection

Anyone running the Comp solid Magnum cam 296 duration .525 lift? Wondering how it does on the street and low end torque feel. I have to replace my cam (long story) I have been running the MP purple Hydraulic cam shaft 292 .508 I have really liked it, good on street, sounds good, have run 12.9 at the track. I just thought this will be one of the only times to do a cam change so just exploring all of my options. Maybe there is a better cam out there. My thought was keep the duration the same just add a little lift. I plan to add aftermarket/ported heads in the future and those heads might like a little more lift? Or if it ant broke to fix it, keep the same cam. details 71 Duster 340 stock x heads 2.02 1.60, 10.7:1 compression, headers, wieand stealth dual plane intake, 2,500 stall, 3:91 gears, 28 inch tires. Any advice is greatly appreciated.
Probably leave that cam in there and just get a little bit more, 3400 stall , converter.
