Actually it's a 451 (400 block 440 crank)
Imho I can say this is the best intake manifold for street and strip big block .
You must use mopar throttle bracket from Mancini p/n Item #: MREAR-1070 or other source for a 383 or 400 cid with 727 auto linkage
My personal experience at the track = 12.87 ET at 109.26 MPH
this set up may be use on 440 but never experience...
