Default Slight miss 500 miles after cam swap

Over the weekend I noticed my camaro started to jerk a little in overdrive while cruising at 55 mph. I can hear it through the exhaust too. Under WOT it pulls hard and driving around normal it runs great, no sign of a miss at all but for some reason with the RPM's low in overdrive around 55 mph it jerks a little and can be heard through the exhaust. I'm thinking it's just the cam loping because the RPM's are low but I could be wrong. Any suggestions on what to look for? I installed new NGK TR55 plugs when I done the cam swap and the MSD wires are only 6 months old. Thanks

where does the cam position sensor pick up on an LS1, maybe there is interference in the signal?

How big is the cam and did you get it tuned?

I did the cam swap myself, it's a Patriot 226/226 585/585 on a 112 LSA. I'm getting a random misfire code but from what I've read that is common correct? It's not tuned yet, it's going next week to get dyno tuned so hopefully that'll fix the problem. It runs great, no idle problems whatsoever but just cruising in overdrive it bucks and misses a little. Could that be the computer throwing the timing off? I've re-checked all the plugs, wires, coil packs, everything and it all looks and works correctly. I de-screened the MAF after I finished the swap, kinda makes me wonder if it's not reading correctly at that low RPM with a load.

The tune will probably fix your problem.
