Description
What is a big block engine?
A big block engine is physically larger and weighs more than a
small block.[4] Larger bores, longer strokes, bigger valves and
ports can lead to truly astounding power production. If a small
block is a quick and nimble welterweight boxer a big block can be
devastating heavyweight. This power comes at a price however,
weight – those added pounds over the front axle of a car penalizes
handling and acceleration, though the acceleration problem can be
overcome with power.
Big block engines were designed to give extra muscle to light
trucks and passenger cars. Its first entry onto the market gave
heavier vehicles the torque they needed, but, like the small block
before it, quickly captured the hearts of muscle car enthusiasts
and hot rodders.
After Chevrolet introduced its big block, Ford and Chrysler
followed suit, offering their own versions of small and big blocks.
Most discussions today about small block and big block engines
refer to Chevy offerings, the similar engines from other
manufacturers are interesting and just as fun to drive as they GM
counterparts.
Big block vs. small block engines: Which one is better?
Both big blocks and small block engines have their advantages and
disadvantages. It comes down to what you’re looking for from your
engine. The small block weighs less, which can give it an advantage
of acceleration and handling; however, the big block has more
torque, which can help it overcome the disadvantages that come with
extra weight.
The big-block guys will say that the small-block weighs less, and
therefore should have an advantage. However, they will also say the
big-block delivers more torque, and has the advantage of better
head flow, so it can overcome the extra weight disadvantage. The
small-block guys will come in and sat that the lighter engine is
capable of running higher engine RPM, and that’s where horsepower
is made.
But, when trying to keep all things equal, we run into a glitch.
Even if we keep the horsepower rating equal – or as close as
possible, there are factors that come into play that you might not
have considered. So let’s add this caveat, keep the engine
displacement equal, we’ll say 427 cubic-inches.
