Quick question, have you dat down with an engine builder and talked about what you want?
Sounds like a catalogue car that will sound cool on paper but will have a crap ton of lag and go no where fast.
Your head is where your power is going to be made and running cam numbers off like that doesn’t mean anything until your dead set on a turbo and a power goal.
I spent 3 months talking to people and reading about turbo vs cam specs before I jumped in the deep end with my builder.
PS there was a purple r33 GTR here in NZ that was a book car and it was nothing special once you drove it, HKS here Greddy there, no power delivery
