Not quite what I'm looking for, but thank you for the post 😁
After reading that, I thought I could hear Jeff Foxworthy saying, "then you might be a redneck"!
My goal is 920 whp with a factory converter ZL1. A modified LSA will get me there, but the block will be the weak link after the rods and pistons. I just hate to buy all the studs, do all the machine work, etc...and have the block fail. The LSA block is all but oil cooled as it is. With all that oil spraying around, all that windage, an easily modified factory oil cooling system... If I buy a Dart SHP Pro block, why not go 427-440? Buy some better 6 bolt heads. Shot for 1800fwhp... No good place to stop.
"With all that oil spraying around, all that windage, an easily modified factory oil cooling system"
All that oil 'Spraying Around' as you put it cost you large amounts of HP.
Reducing 'Windage' is what helps you reduce parasitics HP.
On an 'Wet Sump' you want to keep the oil in the pan where it belongs.

Let's see; 1800 fwHP would require about. . .
=> (1800 * 1.5)= 2,700 CFM, @ around 70°F temperature at the inlet / TB.
What blower might you be considering?
As your engine will be working in 'Compressible Flow',
because the engine will be demanding an 'Equivalent Flow' of ~750 cfm . . !
Remember; the density of air with a blower, means the density
of the air is determined by the square root of the pressure ratio.
So if the pressure ratio (Absolute Pressure Ratio_ABS) is
two (2), then the square root of 2 equals 1.4142
So if we desire to 'Double' the density of the air, then we must
increase the pressure ratio to the value of four (4).
I state the above, because an 440 cid engine will produce
about 890 fwHP to 915 fwHP at 100% cylinder fill.
So the scenario you created, would mean your ABS_Pressure Ratio
would have to be about 4.0.
Going to take a damn good blower to do that..lol
