A 350 .030 over is 355 cid. Chevy made a 348, but that was considered a big block. It was the pre curser to the 409, and was made in the late 50's. A 377, and a 383, are versions of hybrids between the 350, and 400. Cannot say I have heard of that one.
Chevy 350 bored 60 over. .... not the best way to come to a 358... The "NASCAR" way is to use a 400sbc block and a 327sbc crank. High revving and big hp up top.
Block LV+, which will raise its level
NASCAR uses many different engines. but in the sprint cup series. ALL SPRINT CUP CARS use carbourated Chevrolet 350 4-bolt main small block V-8s, bored out to 358. which is 5.7L. approx 800 horsepower.
Small block
It is a small block
"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.
That would be a small block.
It is a small block.
get a big block or bore it 54 over
BIG BLOCK OR SMALL BLOCK DOES NOT DEPEND ON CUBIC INCHES . IT IS THE DESIGN OF THE BLOCK ITS SELF.
Yes.
