Any centrifugally-blown A engines on this forum?

I have a P1SC on my 410" stroker. Originally it was a 360 with about 9.2:1 hypereutectic pistons..non intercooled, no water injection, and running around 10lbs of boost I blew a head gasket within two months.

I rebuilt the engine with Quench Dome 8.3:1 CR forged stroker pistons
Mopar Forged Stroker Crank
Eagle H-Beam rods
Edelbrock Perf RPM Heads Stage II ported by hughes with a stud kit
Same hughes cam as before 489/524 left 218/[email protected] 111 lobe sep.
Commetic Head gaskets
Water Injection
I run a Holley Fuel Injection style fuel pump
Aeromotive bypass style boost sensing regulator to increase the fuel pressure with boost.
I have the same carb only it's a 650cfm though at 10lbs of boost it will flow over 1200cfm and I've never had a problem even with the stroker.
A/F ratio on the dyno is around 12 all the way across
8.75 rear end with 3.23 gears..I used to run 3.91's but I hit the rev limiter before I crosses the finish line at 123mph

I've ran this setup now for over 2.5yrs with no issues at all.

With the 4sp on street legal 8" slicks I have to go real easy through first at the track.
1.87 60ft 12.00 @ 120mph is the best time I've ran on a 95 degree day.

With 9:1 CR the Water/Meth injection Kit is def a good thing.
I don't retard my timing under boost...I usually run 28deg total advance.
Running 8 or more lbs of boost you should run a blow off valve.

Sounds like you have most of the things you are going to need.
If you have specific questions let me know.
