get a big block or bore it 54 over
Small block, and big block use the same flywheel. 400, and 454, are both unique, however, in that they are externaly balanced. 400 will not interchange with any other small, or big block, other then 454. They both use unique harmonic balancers, as well.
bore and stroke a chevy 400 smallblock.
A 383 is a .030" over bored 350 small block with a 400 crankshaft. The 454 is a big block.

400 small block 2brl was the basic engine with a 454 big block optional
No, They won't even begin to fit. 454 is a BIG block and a350 is a small block.
A 350 is a small block and all the engine parts are small. The 454 is a big block and everything is big. Nothing will interchange.
327 is a Small block. 265 thru 400 were small blocks but to confuse you more the 396 thru 454 were big blocks. Unless you really want to be confused, I won't mention the 348 was a big block. :)
Chevrolet used the 350 and 400 small blocks and the 454 big block.
For complete engines, the weight of the average (stock) 400 Pontiac at about 650 lbs. is roughly between the average (stock) Chevy small block at about 575 lbs. and the average (stock) Chevy big block at about 680-685 lbs..
