Dumb Question, yes?

Thanks for the response guys! See, my biggest thing is, size, to know what will fit into what......I've always played in garages and messed with motors that should not fit int type "1" car body, due to size... meaning of, IF the NEW 426 is of small block size, then meaning it should fit into almost ANYTHING with a small block V-8 in it already..........see? This is the issue with the old Generation 2 426. it was HUGE in size......For what it was, even the 440 Wedge, 440 Super Commando, were smaller in physical size then the 426, and it was less CID, but the block was cast, large for the sake of the heads.

The question goes to the type block was the second generation 426, a RB block, or no? I know the first 20 or so blocks were RB, as they were the 426 Wedge, or Max-Wedge motors, wasn't till Nascar tryouts that they cracked and needing beefed up a bit.....See?

Then to add to this, the new 426, and the BRAND new 440 Hemi, will those fit in anything with a 5.7 in it already, I mean drop in bolt up fit? NOT set up as far as controls and electronics and all that I mean, literal physical fit and bolt in place....OR are they a big block?

My neighbor has a new '14 pick-up with the 5.7 and he asked if any of the "new" old Cubic inch motors fit into the existing location without physical modification. And here I am a Mopar fanatic, and I couldn't answer him, but told him, I would find out.....

I mean he's got a 2014 Ram, all "Blacked Out" with the extended cab (4 door cab) but not "Crew Cab" with the 5.7 in it, and he likes my 67 better, and mine only has the 383 in it....Which is a RB block, and it makes a dwarf of his 5.7 Hemi......
