The main problem is CR cause it limits cam choices. What's the biggest you can go with stock CR comp xe268h/xe274h/xe286h ??
Only using comp cams as a reference

Is stall change gonna go along with cam change ?

How deep are you willing to go with gears ?

Probably can get away with more cam with deep gears and more stall.

Airgap 750 and headers nice additions.

Nos is probably the best route for drivablity and to reach goal. Or at least can go more mild with bolt on's.
