Default Thoughts on my CAM selection for my 400ci Engine Build

Hi everyone, I'm new to this site and was hoping I can get some feedback on my engine build. I'm mostly looking for some feedback or possible suggestions for my CAM.

I'm going with '68 #16 heads 2.11/1.77 valve heads (75cc) and trying to bring my compression ration down around 9.3:1 so I can run pump gas (91/93 octane)

1966 Pontiac GTO
-‘73 400 ci block going to be bored out 0.30 over from 4.12 to 4.15
-Tri Power Carbs being put together by Pontiac Tripower
-‘68 #16 heads 2.11/1.77 valve heads (75cc)
-14cc dish pistons
-Ram Air Exhaust Manifolds
-2.5" Exhaust with Flowmasters
-4 Speed Muncie M20

I decided to stick with a hydraulic flat tappet cam and have been recomended Crower 60919 Hydraulic Flat Tappet Cam (Duration: Int/ Exh 304/316, Duration @.050” Lift: Int Exh 231/240, Lobe Lift: Int/Exh .313/.313)

I was advised this setup would get me around the 360-375 HP range.

I've read this is a good CAM for a 455 or stroker and wondering if it will work for my setup while trying to achieve the 9.3:1 compression.

Any feedback is greatly appreciated.

Thank yoiu in advance
