Stroker Kits - Even Today, There Still Ain't No Substitute For Cubic Inches!

If you're looking for extra torque and horsepower for your engine, there are of course many options. From simply fitting a set of headers, or having your engine management system chipped, right through to the more complex business of turbo charging and supercharging.

However, there's another tried and true method that's been used by petrol heads for decades: make your engine bigger.

Boring is one way of doing it. This is the process of machining to enlarge the engine's bores (usually to straighten out worn cylinders) and fit larger pistons. Trouble is, while some engines have enough bore to hone out and realise some gains, many engines have limited space for boring, which makes the extra grunt relatively meagre.

Another route to greater capacity - and to bigger gains in torque and horse power - is stroking. What is stroking? It's the process of fitting a crankshaft with greater swing or 'stroke' and thereby increasing the engine's displacement. (It also, it should be said, involves fitting different con-rods and pistons to cope with the new crank).

The old adage, 'There ain't no substitute for cubic inches' is still valid - despite all the high-tech advances of the last 25 years or so.

While there's plenty that can be accomplished using technology, simply making your engine bigger can produce a very healthy gain in both horse power and torque. Old fashioned? Maybe. Effective? You bet!

Stroking first became popular with drag racers. When The Big 3 began producing big-block engines, they realised that by taking a big-block Chevy 400ci crankshaft, for example, and fitting it to a small-block 350, they would end up with a 383ci motor. This is a more significant increase than can be achieved through boring.

Of course, this didn't mean they ignored big-block engines; drag racers began stroking them to produce motors of huge displacement.

Inevitably, tuning companies caught on to the trend for stroking and began to produce after-market components. Many companies now sell stroker kits (basically consisting of crank, pistons and rods) as an off-the-shelf solution.

And since they cost only marginally more than components needed for a standard rebuild, they make perfect sense for anyone who's looking for extra power and torque (even for folks who may not have considered performance modifications).

They're a very straightforward (and cost effective) way to make some serious gains and are popular with many truck and sports car owners. Stroker kits are also popular with owners of imported cars - since they often have small-displacement engines, they can usually benefit greatly from some extra capacity.

And of course, if stroking is coupled with other mods such as a re-map, performance manifold, headers, etc., even greater gains are possible.

All in all, stroker kits are a great option for anyone who wants to get more from their car. If you're going to rebuild your engine, a stroker kit is a simple and relatively inexpensive way for you to get more bang for your buck.
