Sizing the blower properly for boost level is a thing just like you would a turbo. 9 psi is right in the meat of the LT4's efficiency range and way below the 2650. So the 2650 is going to build boost just like a centri. Probably will be around 4 psi on the stab of the throttle and build to 8-9psi by redline.
I honestly do not know why the 2300 was discontinued because the 2650 is way more unit than most need. I have seen ZL1 guys install a 2650 with canned tune and barely run any faster in the 1/4 mile vs stock blower. LT4 blower makes a lot more sense for what you are trying to do. The 2650 is a awesome unit don't get me wrong but unless you plan on pushing north of 850whp there are lower cost options available. Just reach out to any popular YT shop (RPM, LMR, LMP of Maryland). They all going to say the same thing.

Agreed, I wish the 2300 was still an option.
We should note, the 2650 will be easier on the high compression LT1 than a 1740 because it hits hard well below peak torque.
Boost pressure at Peak Torque is what we have to think about when boosting high compression engines.
