How much is a Chevy 396?
While a forged GM crank for a 454 could cost as much as $400 today, a forged 396 crank sells for about $75. And a rebuildable 396 short-block will usually only set you back less than $200.
Is the Chevy 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.
How much HP does a 396 have?
Torque/Horsepower The 396 was offered in several configurations and produced different horsepower and torque ratings, depending on its intended application. The 396 with a 10.25 compression ratio produced 325 horsepower at 4,800 rpm and 410 ft. lbs. of torque at 3,200 rpm.
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 do I know what 396 I have?
Big blocks are named after the size of their displacement as measured in cubic inches (e.g., 350, 396, 440 and so on). It is easy to identify a 396 Big Block engine made by Chevy as the engine code is stamped above the timing chain cover.
Why is a 396 A big block?
Typically, big-block engines have displacements of greater than 400 cubic inches and small block engines have a smaller displacement. The Chevy 396 engine is an example of an engine that has a displacement under 400 cubic inches but is considered a “big block” due to its architecture.
What is a Chevy 396 bored .30 over?
If I’m not mistaken, a 396 that’s bored . 030 over is 402 cubic inches.

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.
How far can you bore 396?
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.
Can you put 454 heads on a 396?
For example, tossing a set of 454 open-chamber heads on a 396 could radically reduce the compression ratio because of the roughly 10cc larger chamber on a short-stroke engine. Production big-blocks all the way into the mid ’90s were always flat tappet camshaft engines.
