I love this topic! LOL
If you were in the 550ci range (4.500stroke with a 4.400bore) with a set of P51s @ 10.5-1 and a hydraulic roller it would make prodigious…frightening amounts of torque all day, everyday!
You wouldn’t need (or probably want) to spin it very hard to make your passengers pee themselves.
Aluminum 385 Blocks: You can get them from Carrol Carter at C&C motorsports
C and C MotorSports.
The Roberts Design 10.320 deck, wet block is $5775.00
If you are patient, they do turn up on the used market but they are getting harder to find. I got one on Ebay a few years ago. You can also find them on Racing junk and the 460ford forum.
As far as weight. The factory blocks range from 210-235 lbs depending on casting and bore size.
The A-460 block comes in at 302lbs un-machined and about 260lbs @ 4.625
My un-machined A96 (no longer avail. Ford Motorsports Block) weighs 160 lbs. It should come in between 115-120 lbs @ 4.600. That puts a complete engine in the 550lb range. I would love to see a BBF down @ 500lbs. LSM in Michigan has a CNC profiling program that can remove 30- 40lbs from one of these blocks ( if you machine the main caps too.) Add a remote electric water pump, no distributor, magnesium intake…maybe 490ISH….
