383 vs 400

Maybe, but not probable. That's siamese block territory.

IDK dude can be lying, but here it is, B1 409 bbm 1008 hp @ 8,900 rpm results is shown at 2:30.

It makes 662 lbs-ft @ 7,700 rpms that's 1.62 lbs-ft per cid (409) that would be near max effort, It's near maximum ability in torque department.

max effort

The crank and rods are likely resting in the blanket. lol

I hope not.....for their sake, that's a lot of work to get that combo there, and execute a strategy to have it live.......

I'm shocked their just using a motorhome block.

Given a similar bore size and the same induction, valve train and CR a larger CI engine will make more low end torque but the HP will be very close and occur at a lower RPM.

Wasn't the B1 stuff made for 400 blocks?

i think *some* of the 400 stuff had beefier mains and webs and thicker walls.

as with everything mopar, it's just as likely to be a motorhome as a cordoba or 2bbl truck motor.
