They are becoming more scarce but many engine machine shops can still get or have, the blocks. Remember, they have NO water jacket, so if it's for regular street use, you would be better off getting an aftermarket block, for example a 426 small block from Sunnit or Paw or building a 383 stroker or just throw a small roots type blower on any stout engine.
No, they did not. The smallest big block Chevy is the 396. They also made a small block and big block 400.
Chevrolet used the 350 and 400 small blocks and the 454 big block.
The 1972 Chevrolet small block 400 cubic engine value is dependent upon the condition of the engine. The value of a running engine is approximately $500.
Yes as long as it is not a small block 400 ci.
It depends on what year it was made, and what it was installed in. Chevrolet never made a high performance 400 small block. They used the 396/402 for high performance applications. The small block 400 was typically installed in heavy cars like station wagons.
a 400 small block Chevy has a 4.125" bore.
The Chevrolet small block 400 will bolt in place of the 305 but be sure to use a 400 flywheel or flex plate. Do not use the 305 flywheel or flex plate on the 400.
In the 1970 Chevrolet Impala, the 250 L6, the 350 V8, the 400 V8 (small block) and the 454 V8 (big block).
1981 was the last year the 400 small block was made.
Yes.
"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.
The firing order for the Pontiac 400 engine is that the small block powers the big block.
