A 345 taken to a 393 with Supercharger is not likely going to hold up very long be prepared for lots of issues. It's your dime and good luck.
Go ahead. Ask me how I know a 392 stroker is a great build...

Which crank? Who’s combo is it? Why they go 8:1? Just curious
Callies 4.080 8 counterweight. They have a 4.050 8 counterweight off the shelf. Custom pistons
8:1 compression lets you run more boost. With them same octane. Low CR higher boost makes more power than higher CR low boost/ high CR NA engines.
1 CR = 2% HP increase avg.
1 psi = 16-20hp avg.
1psi boost requires 1.5 octane
1 point CR requires 3-5 octane

Ethanol is forgiving. Pump gas not so much. Run ethanol and 10.5:1 compression and you won’t have to max out the blower to achieve your desired hp level. Spinning the blower harder causes heat and it’s own set of problems
