Ragtop 99

That's at when you are well into the throttle. At light throttle in town and at cruising speeds, I would expect the A/F ratio to be the same as an NA car.

More cubes do take more fuel, but that can be partially offset by a higher CR if the owner chose that as part of the build.

We have two offering for a long block for the 416

The first is with MAST LS3 heads, custom HKE/Comp cam street grind 525-550 rwhp $8799
Second is stage 2 LS3 heads custom HKE/Comp cam street grind 500-530 rwhp $7355
Both feature Morel lifters, Melling Hv oil pump, HKE thick-walled pushrods, double roller timing set, ARP head bolts.

MAST head combo will have YT Ultra lite rockers, LS3 heads will use your OEM rockers (we will rebuild them)

Both are precision built racing engines and will have good street manners, power numbers are RWHP estimates for a standard transmission equipped C6

I would expect more in the 575rwhp for a full bolt on h/c 416 in a 6 speed?

Depends on how its cammed. Our street cams are not a max effort top end cam, they are designed for power under the curve. We can certainly cam if differently for a more aggressive application. Those are semi conservative numbers
