sorry to hear about your dad, A 904 tranny is for smallblocks so is a 727.But 727 also went in bigblock rides.You can measure the bolt pattern with a tape measure on your 440 or if ya got a real keen eye look at the bell housing and look for a nice fat round housing.A small block housing will have a flat surface to one of the sides probabley the right side lookin at the back-side of the tranny.Rear-ends are a little bit trickyer.8.75 rears have a third member that loads from the drivesahaft side and a nice round backside.This rear would be desirable for your car,unless you find a dana 60 wich is ultimate beef.It has 10 bolts that hold the pan cover on. More than likely the belvy has a 8.75 already in it,unless its already pulled.The D-60 is asimmalar rear that was in 3/4 ton pickups.It is king beef for drag racing.Hollor if ya got anymore questions.Try and help as much as possable
