just wanna know cuz i wanna try and build an engine for my car with my father-in-law and im lookin into a 351, and there were two types</P>


i think it was a 351 windsor and a 351 cleveland </P>


wind being the long block?</P>


and cleveland bein short?</P>


just wanting know the advantages about each, and would a long block even fit in a 92 mustang?</P>


</P>


oh yea can you kind of put your answer in lamens terms too? </P><edited><editID>Obsol3te</editID><editDate>37994.3707060185</editDate></edited>

 

dude a short block is just the block, and internals. a long block is the bottum end, heads, oil pan, and usually no intake. both the windsor and cleveland are small blocks.

 

so the term LONG block is just a "more complete" engine?</P>


i thought one was bigger/smaller in the long run</P>


shows how much i know</P>

 

and how come i hear that big/small block are like 2 totally different things?

 

small block= small cubes &lt;427
big block== big cubes 427&gt;

or something around there....

 

*L* it's the size of the block 2 groups
big & small

 

Except that's not right.

360/390/460 are all big blocks. It's just size of the block, not the displacement

 

ho..but it was funny*LOL* some have no clue

 

Big blocks and small blocks have different external dimensions, big blocks being obviously bigger. The reason for big blocks and small blocks is that small blocks can only displace so many cubes given their size, so to get more cubes out of an engine, they had to cast a larger block to get bigger bore sizes and longer strokes to get more cubes. Big blocks are also heavier than small blocks, but makes up for it with more power and torque.</P>


A short block is what is also called the bottom end of an engine. The block, rotating assembly (crank, rods, pistons), oil pan, and sometimes camshaft are part of the shortblock. A long block refers to the short block including heads.</P>


A 351C and 351W are identical in dimensions, and both are small blocks. The difference is the 351W is about 20 lbs. lighter than a 351C. Cleveland and Windsor refer to the plant in which the blocks were cast.</P>


You can fit either a big block or a small block into your car, but to use a big block would require some modifications, which judging by the fact Iassume you're new to all this, you might want to stick with a small block at first. </P>

 

I thought the Cleveland had differences, different heads or something. (don't really care, since I won't be buying one)
