if the 425 has the same bolt pattern as the chevy 350 you wanna put in, YES. if its a cadillac 425, maybe. heres what the chevy 350 should look like, this is where the bell housing bolts to the engine.



this is a Buick/Olds/Pontiac engine, see the difference? they make plates that adapt to each other, but most people just find a B/O/P trans....you decide.



sorry for drawing quality but you should get it now. just look at the trans and youll know which one you have, a point at the top is a chevy, and the dip or arch is a Buick Olds Pontiac

idk, is the 425 a big block? im assuming so, so if they are all cadillac engines and all big blocks, then in theory they should.
so will aftermarket part for 475/500 fit on a 425 for ex. valve covers, intake manifold

no the cadillac tranny wont fit on the chevy engine but u can get an adapter plate , and yes the parts from a 425 , 472, 500 and 386 are interchangable, as far as a chevy engine bolting right in a cady ive heard that the mounts are the same im not 2 certain
