Magnum 360 build. (HP/tq?)

Thats a lot of cylinder head for a small cam did you calculate CR and DCR ?
You're definitely not gonna run out of breathing from that head. It's a little hard to judge it's a bit of an odd combo the cam probably will peak around 5000-5250 rpm maybe higher cause of head and intake So 375 hp @ 5000 rpm to 394 hp @ 5252 rpm.
