Finally !
 

Now the really smart guys have their own forum. Life is indeed very good :3DSMILE:

What do you mean "smart guys"? Does this mean that you believe that sb owners are smarter because they try to get more out of less? The sb guys are often accused of having a Napolean complex.

I believe to each their own. We are all smart in different ways. We all have different preferences. I am glad to have a place to share concerns.

I note that you have a 396 stroker. The outside is sb bout the cubes are bb. Does that make you sb or bb?

I am getting a stroked 351W. I am in your boat. I just was reacting to "smart guys." The comment smarts.

I prefer to think of it as stealth. :3DSMILE: It's kind of like wearing baggy pants as opposed to tight jeans. Leave em guessing until the last minute.

Call me Carroll. Only people that do not know me call me by my last name.

I like high performance in a small package. It is good to have a sb site.

Where is the line drawn between BB and SB anyway? What is the magic number of ci that shows which is big versus stroked? I think we should define this for the record! This is a serious issue! IMHO after you break into the "4's" that your a BB.

SB, BB,,,it has little to do with the "cubes". It's about the "model" of the engine. In Chevy land (you know the "dark side") the "mouse" motor and the "rat" motor refer to the engine design. 265, 283, 327, 350 and 400= small block mouse motor. Heck the "small block" 400 is bigger than the Big Block 396 "rat" if "cubes" is all your referring to. But there is a BIG difference between the two engines design.

It gets a little "fuzzy" in Ford land (where the sun is shining and the grass is always green) 221,260,289,302,351W,= small block.

The FE series, is clearly a "big block". But what about the early FE style engines? Weren't they also produced in the 330 cubes range? Based on "cubes" alone that would make them small block? The old 352, 390, 427 I always considered "big blocks" because of their "design" characteristics.

A "big block" of any size will by it's design generally weigh more, be "heavier" built than a small block. Typically turn lower rpm (in stock form) and be designed for more of a torque (truck, heavy duty) type application.

A 351W, even bored to 427 cubes is STILL a small block! A 427 destroked to under 400 cubes is STILL a big block. So what the heck is a 351C, 351M and 400? Which were mostly used in "truck" applications. Small block me thinks!

The line to me is still a blur between sb and bb. I recognize that a 351W is still called a sb and a a 427 is still a bb no matter what cubes on the inside. This bothers me. When an engine is significantly modified (e.g. stroked), it is no longer the same engine. If it is not cubes, what makes an engine a bb or sb other than the original manufacture definition for the block? What design elements distinguish the two classes of engines?

Based upon the comment that bb are used in "truck" applications, does the following hold in reference to Cobras?
-- bb are for the Cobra truck guys
-- sb are for the Cobra car guys
Only if the world was so simple.

What's sb vs bb
 

Carroll
I say external diminsions and weight are the measures. Like comparing floats to anchors. **)

"Like comparing floats to anchors." This sounds like an emotionally toned sb bias, not a unbiased comparison.

Of course, some sb fans believe that a bb is only good for anchors.

Ha ha,,,Cobra truck! The point is some engines found a home more often in a truck application than in a car application. Me thinks the original design parameters were for "truck" applications". For a car the FIRST thing to do is get rid of the low rpm high torque cam and intake!

Guys
It is OK to say something nice about BB motors once in a while.
All of the Moderators on this site are BB owners and we don't want to upset them too much.

We have our own place to BS now and we don't want to be sent back to mix it up with the other guys.


Cranky:3DSMILE:

big BLOCK = big block
smal BLOCK = small block

Internal dimensions irrelevant. (its not that hard, guy)
