Is a 396 a good engine?
The 396 is a good revving engine, so you’d want to run a steel crank so it would live at the rpm you’d have to run it to make HP. And probably a roller cam, as flat tappet cams in big blocks have a nasty habit of “going away” relatively easily.
Are 396 and 454 blocks the same?
The blocks are the same with the exception of the bore of the cylinder when the cast was made. The walls will not allow for that much bore. If you wish to use the 454 crank and rods with the 396 block you can purchase a set of pistos with the corrocponding compression hieght and have a stroker 421 CI engine.

How far can 396 be bored?
4.250 inches
With a bore spacing of 4.84 inches and a potential maximum safe bore size of 4.625 inches (theoretically, for the big-block design-most 396 blocks can only be bored out to 4.250 inches), the 396’s 4.094-inch bore diameter is laughably small.
Is a 396 and 427 the same block?
The 396 is its own block, and the 427/454 can share the same block. If I were building a big block I would go 454, and probably just buy a crate motor. Mostly due to the majority of big block being the truck blocks. Unless you wanna go for a 496 big block.
How far can you bore 396?

Is a 427 a bored out 396?
Registered. It is not a very good idea to bore the 396 block out to the 4.250 to acheve the 427 bore. There just is not enough cylinder left but it is possible and many have been done. You would definitely need the 396 block sonic tested before you would know if it will work.
What is a 427 tall deck engine?
The tall decks have a taller deck height or it is farther from the crank center to the mateing surface for the heads. They are a low compression engine as in 8:1 low compression and they have peanut port heads. They take a wider intake manifold probably pretty hard to find a performance intake.

Is a 396 really a 402?
A 396 is a 396. The bored 396 (making a 402) was used by GM and branded as a 400 (along with the 400 smallblock) for a time. The exact size of displacement is/was often rounded. If you calculate the actual size of a Chevy 350 for example it’s probably a bit shy of 350CI, as are other engines.
