I have a stupid question...what is the difference between a 400ci big block and a 400ci small block? Also, what makes a big block a big block? Is it the stroke, bore, v angle, or what?

Yeah, I'm still not getting it. The physical block size wouldn't that have to do with the stroke too? I'm not trying to be difficult, but I really still don't get it.1997 Formula WS6

You can also have a large box that contains small contents, you could also cram the same contents into a smaller box. of course the best of all is a big box with big contents.

Most manufacturers build engine groups or families- the small block chevy SBC, was a single casting that could be bored to different cylinder sizes and use differing crankshafts and could be built as a 283, 305, 327, 350 and even a small block 400- externally all the same, used same manifolds, distributors, etc.- the big block was a different casting, and, depending on what piston diameter it was bored for and what crank was used, could be a 396, 427 or 1 454- the transmission bell housings and engine mounts were different for small block/big block-
All bets are off if you go far enough into the past to have Pontiac or Oldsmobile big blocks and small blocks- they tended to be different animals totally.
Chrysler did the same with the 273-318-340-360 and the 383-400-440- again, the hemi was a whole different family.
Ford small block was 260-289-302 which became the 5.0. They had a couple big block variants, and to confuse things more, they made a 351 engine in both big blcok and small blocks, sort of like Chevy's 400. In the Ford world it was Clevland or Windsor for the 351-
HTH- I have lots of useless trivia, I remember less and less as I get older2001 Z28 A4 - 160 deg t-stat, 3.42 gears, WS6 sway bars, rear springs and shocks, UMI SFC's, Torque Arm and STB, leather Firebird seats, Borla, SLP Y-pipe and lid, ZO6 cam and springs - 332 RWHP and 346 RWTQ, not bad for 'almost stock' - work in progress

In Fords there were 3 351s. A Windsor, Clevland a a Modified. The modified also came in a 400. They also had a 360, 390, 428. And add in the SOHC 427 side oiler. Then there was a 429/460. My engine bulding neighbor buddy built a 700+ cubic inch 460 motor that put out something like 1500 horses on pump gas.
Cadillac had a 502 cid.
