Detroit Bill: I see Brent has the 390-based 431/445 on his Web site at $13,350 (Lykins Motorsports, LLC). That seems competitive with the 385 and a bunch less money than the Pond block, while providing the authenticity of an FE. Win/Win!!

The closest I could find on Brent's dyno pages to the above engine was this:
487 ci FE, 536 hp @ 6000, 583 lb-ft. 4.270 x 4.250, Scat cast crankshaft, Scat H-beam rods, Diamond pistons, 10.5:1. Comp Cams hydraulic roller, 245/248 @ .050", .634"/.634" lift, 110 LSA. Edelbrock RPM heads with competition valve job, Edelbrock Performer RPM intake, Quick Fuel BD-850 carburetor. Stuska dyno.

So, then 487 FE has a bit bigger bore and displacement, but same crank and stroke and, as near as I can tell, pretty much the same components. Knock off a bit for the CI and the 431/445 still looks like it's just shy of 500 HP - well over the 400 HP that's supposedly 'usable' on street cars.

Rather than speculating - let's ask the builder.

Brent: What does the 390-based 431/445 typically pull on the dyno?
