I would think his dynamic compression would be down with that much cam and make it want more timing.

Motor has not bin run was built five months ago and never installed still in crate.Sounds like a pretty mild cam to me. I would think, if you stayed off the skinny pedal, listen for detonation, and pull the plugs periodically and check to see if you are getting knock, running rich/lean, you could probably drive it for a while without a tune. You'll know right away if it doesn't sound right ie. lean pops out the intake, hesitation, idle cold and hot, etc.

BTW - The builder should have degree'd the cam and, like mentioned by @Gramps, have the cam card. Has the engine been broke in yet, big deal!
I agree, probably more fuel too. I was just saying he should be able to safely run until he gets a tune if run carefully! YMMVI would think his dynamic compression would be down with that much cam and make it want more timing.
I got quoted $3000 to have a stock cam put back into this motor before I install it. There's noway id dare to try a cam swap myself that's a job I'll pay someone that knows what there doing but $3000 for a cam swap seems way to much.
So I purchased a completely rebuilt motor for my 98 the motor is from a 97 it's a 5.7. The guy had it gone through completely and did some upgrades and updates mainly stuff like high output oil pump a timing chain and gear upgrade molly rings upgraded main bearings. He had a hydraulic roller comp cam 460/460 lift, 280int./280 exh duration, installed. Problem is I live couple hours from the nearest tuner would I be able too install the motor and drive it around as a daily driver and till I get time to take it in and get it tuned?
Well plans changed if I was putting a stock motor back in ya in my opinion a tune specially on this old of a truck is a waste of money but now that I bought this new motor with a cam in it I don't think I really have much of a choice at this point. But we are getting busy at work starting to get ready for seeding so I wouldn't have time till seeding is done to run my truck to the city to be put on a dyno and tuned. From what I gather I can run it for time being as long as I keep out of it as I do anyway but yes it will be getting tune with this motor.Another option would be to have blackbear tune your ecm for that and then you would be go to go.
From what I have seen in the past - you actually have no plans to ever get this tuned, so you are actually seeing if these guys will tell you to run it forever as is. Then you will complain that your untuned motor is slow again haha. Hopefully I am wrong.
Think what you want It's a cammed 350 it's getting dyno tuned atI will believe it when I see it. I still think that you have no plans to ever get this tuned, and this thread was your way of asking the experts what would happen if you don't.
For a few hundred bucks, blackbear could send you a new ecm that would work well. It wouldn't be quite as good as an in person tune (if the tuner is ok), but it would still be really good. No down time, easy swap, inexpensive. This is what most rational people would do in that situation, but here again - I doubt that you have any plans to tune this...
