NONE of those high dollar parts are at all necessary for a low horsepower 360. I think we all know where that engine program is going if something doesn't change. No ones gonna buy.
No offense but the 427 you built isn't a comparison. Its probably 50% more horsepower.

The last engine I built was a 408 with indybrocks and was very reliable and full roller. I had 6500 to 7000 in it.
If you all think 10k 360s that are 400 horsepower are gonna sell you're out of your minds.
