No, GM made a 396 big block, dodge made a 383 big block, some OLD hemis are 392
No, they did not. The smallest big block Chevy is the 396. They also made a small block and big block 400.
396 big block
about 685 pounds dry
yes
A 402, is a 396, .030 over. With a thinner cylinder wall, it will heat up a little faster, and higher. Cylinder head warpage occurs around 230, or 240. Your motor should never run this hot on a consistant basis. 180, to 200 degrees should be the normal operating temp.
1965 first in vettes
180, to 210. Anything above that should be considered over heating, and requires attention.
180, to 200.
There was a 402, which was a 396, bored .030 over. No 403.
No it is not an interference engine.
"The v8 350 is a small block Chevrolet motor.....................it became a big block at 396cubic inches......so anything smaller is a "small" block" this is a little misleading. a 350 is indeed a small block. a 396 is indeed a big block. but you can have a small block that is (internally..cubic inch wise) actually larger than a big block. for example GM made a 400 cubic inch small block. internally it is a larger engine than a 396, but the outer dimensions of the 396 are larger than the 400 small block. and the external dimensions and cylinder head design are what make a small block a small block, and a big block a big block. a small block engine simply has a physically smaller block...a big block is called a big block because it's block is bigger than that of a small block.
