Phreakish,
Post #121. You should tell Chrys that they didn't need to increase the diam of the pick up tube in the 426 Hemi with the larger pump pulling harder on the oil.
At the flow rates for the engine OP asked about, which isn't a hemi - nice shift of the goalposts, the velocity through a stock pickup is fine at typical speeds for a hot street motor.
I haven't looked up flow rates for a hemi, but I bet the bigger pickup is sized to the necessary flow, or for dozens of other reasons including wildly different applications and budgetary concerns for the different engine families. We know hemis cost substantially more to produce, and they went into luxo-barges and race cars. LA motors went into everything and so the engineering constraints are vastly different. Worlds apart, even.
