That pump looks small. My Bosch intank is like 3" in diameter.

It does look small compared to others I've seen.
This is a Holley Universal unit, 230lph @ 45psi.
It seemed to do the job with the TPI, and should be fine with the LT1 but I am not to sure about the 150-200 shot I'll be running.
I may end up adding a second pump as the primary and setting the Holley as a booster straight to the 2 fuel solenoids. Not sure if that is a good idea, but it sounds like a good one.

An in-line pump will act as a restriction to an in-tank pump when it is off.
An in-line pump will do very little to increase the fuel volume if the in-tank pump is of a lesser type / factory.
Your best bet is to buy our proper in-tank Walbro 255L/Hr high pressure pump (RX-GSS340LT1). If you are planning on making 450RWHP+ then the complete system should be considered (RX-FLT1-GSS340LT1-FPKG-2).

PS. Walbro and Airtex (T-Rex) supply pumps to Holley, MSD, FAST, Accel, Grantelli, Paxton etc... The in-line Walbro GSL392 is a higher output pump than the T-Rex.
