cam size

This question is for all the tuners out there. How big can you go with a cam and it not need tuning. I need to know how much duration @ 50 on the intake and exhaust side with a 112 lobe center that my 92 speed density system (730 ecm) will handle. I am looking at a lt4 hot cam or maybe just a bit bigger but I don't know how big I can go on a 350-360 CI and it still be a good daily driver and run well. A holley stealth ram will be used as well but this question is really geared for the ECM and prom and how far I can go with it. Thanks in advance.

Re: cam size

Not worth the trouble to swap in a step larger cam and not tune. Put in the cam you desire then tune it.
