Ls6 cam in my ls1
For the amount of work and tear down, I don't think the LS6 cam is worth it.
2002+ LS6 cam
204/218 int/exh @ 0.05" duration
0.551" / 0.547" int/exh lift
117 LSA
224R
224/224 .581"/.581"
112 or 114 LSA
You can save a lot by using new GM ls6 springs $70. If you put in any bigger cams the springs will cost more.
I'm in the same position right now, I dont want to put in a wussy cam and do all that work when I can put in a cam that can make 30-50hp, even though it costs more.
Replace the timing chain at least with a Ls2 chain $40. Replace the oil pump. Even the new stock oil pumps from GM are better then the ones made back in the day for the f-bodies. Use new o-ring seals also.

Would I choose something else? If I had a few hundred more bucks, sure... Shoe string budget and I could do my own labor? Probably not.

Lots of good info here. A 224r is a good cam but it needs to be at least a 114 LSA to have a shot at passing. Its not just the sniffer test you have to worry about its the whole diagnostics system to include but not limited to knock sensors, misfires, etc.
