Why not to use a small-block Chevy engine
From Crankshaft Coalition Wiki
The small block Chevrolet engine is popular, reliable, powerful, and has almost unlimited potential. However, the use of small-block Chevrolet engines (specifically, the 350) is controversial in hotrodding culture.
Pre-1949 cars and trucks are generally where engine swaps are most common and the builder has almost total control over the choices he makes. Those who oppose the use of small block Chevrolet engines typically approve the use of SBCs in muscle cars that originally came with them.
Those who oppose the use of such engines offer several arguments in support of their point of view.

[edit] Mechanical
Small-block Chevrolet engines commonly (not always) find themselves near the lower end of the power spectrum. Greater horsepower and torque values may often be obtained by opting for another engine choice. (this needs more detail, especially comparisons of specific horsepower figures)
The SBC is regarded as "reliable and cheap to build". However, it is not the only reliable and cheap to build engine. Many other similarly reliable choices exist, and they are only marginally more expensive to build. Examples include Ford's 289-302 engine family, and Chrysler's 318-360 small blocks"(citation needed)" (this family of engines has a rear sump pan, just like the SBC, and can be easily installed in most hot rods)
[edit] Cultural
As with many hobbies, originality is prized among hotrodders. Small-block Chevrolet engines are fairly common, so those who use them are often forced to sacrifice the bragging rights that typically accompany an unusual engine choice.
By opting for lesser-known or more original engines, hotrodders can preserve and enhance the cultural and mechanical diversity that is essential to hotrodding culture.
Oftentimes, a less-powerful (or notoriously troublesome) engine will be well received in the hotrodding community, simply because it's original. (give examples here)
[edit] Originality, creativity, and individuality
Many people seem to apply their originality and creativity when making paint and interior choices, but their individuality is not similarly reflected in their choice of engine.
In the automotive world, as in most hobbies, the price paid for being an individual and a leader is almost always worth the extra effort.
[edit] Engine fitment issues are not insurmountable
Dealing with clearance issues or fabricating engine mounts for non-SBC engines is not really that difficult. (this could use more details)
[edit] Understanding price
A teenager working on his first car may very well be financially forced to choose an SBC. However, for someone who's spending $10,000 to $20,000 his prize street rod, the cost difference is negligible.
Also, unique hot rods with unique engines may have higher resale values than cookie-cutter SBC rods.
[edit] Historical
By focusing on building and running lesser-known engines, hotrodders are able to preserve the historical legacy inherent in many of the less popular (but more notable) engines. By creating a demand for such parts, individual hobbyists can help to support the businesses and parts suppliers necessary to fuel the perpetuation of engine history.
