All Dialed In: What is Tuning Worth?

Tuning is an important element when looking to maximize the power output of any combination, but what happens if you miss on the tune?

Words and Photos: Richard Holdener When we run tests on intakes, camshafts or cylinder heads, one of the questions we often get is, do you tune each combination? The obvious answer is yes, as tuning each combination to maximize the power output is the only way to know the true difference between them. This becomes even more critical when the ... Read More »

More Than Cams

Think of this stock, rebuilt 302 Ford as a blank canvas, with nothing but power potential!

Words and Photos: Richard Holdener By now, everyone should realize that COMP Cams offers an impressive array of cam grinds for most performance applications. You would be hard-pressed to find an application where they didn’t offer an off-the-shelf cam grind to suit your needs, but they also offer custom grinds for those wanting something special. After the factory adopted them, hydraulic-roller ... Read More »

Attitude Adjustment: Valve Lash for Power

A change in valve lash on a solid flat-tappet (or solid roller) cam can change the attitude of your motor!

Words and Photos: Richard Holdener Whether you have a Ford, Chevy or Dodge, one of the key elements in improving the power output is the right camshaft.

The obvious answer is adding boost to a pair of 5.0L Fords, one stock and one modified, of course! In fact, the great thing about boost from a supercharger is that it will improve the power output of ... Read More »

The Easy Way Out: Nitrous That 5.0L

The simple solution to more power was to add this Perimeter Plate nitrous system from ZEX. The kit included everything needed to run up to an extra 300-hp to our little 5.0L.

Words and Photos: Richard Holdener  When you go looking to improve the power output of any motor, there are a lot of different performance choices. Some gravitate to increased displacement, as there is no replacement for displacement, especially if you are looking to greatly enhance torque production. Nothing bolsters torque like a stroker kit, but that isn’t the only avenue ... Read More »

Fuel Fight: Injectors vs Pump

Increasing the power output of just about any motor is a simple matter of adding boost. A supercharged late-model Hemi is a serious performer, but not without enough fuel.

Words and Photos: Richard Holdener When it comes to maximizing performance, there is no better time to be an automotive enthusiast than right now. Not long ago, if you were rolling with 500 hp, you had little to fear out on the mean streets. Time and technology have marched on at such an accelerated rate that 1,000 hp has quickly ...

Let’s Talk Torque: LS Truck Upgrades

We all know a cam is the go-to upgrade for any LS, but for truck guys, mild is the new wild, especially when you combine it with a cheap set of cylinder heads!

Words and Photos: Richard Holdener We all know that adding a cam to an LS application is the go-to method of power production. The question then becomes, how much cam do I add? Cam swaps can easily improve the power output of an otherwise-stock LS application by over 100 hp, but are all LS owners looking for maximum power production? ... Read More »

Building Better Boost: Turbo LS Cam Swap

Why do you need to upgrade your cam when you have boost?

When it comes to improving power on almost any motor, few things can rival boost. This is especially true of the LS platform, as they seem to take to boost like a proverbial fish to water. The great thing about boost is how easy it is to get extra power. Whether it comes from a supercharger, or (like in our ... Read More »

5.3L Accessories: What Are They Worth?

How much power is a fan worth, and how the hell do you get these stupid things off?

Words and Photos By: Richard Holdener One of the most common questions we get while dyno testing our typical 5.3L LM7 LS motor is how can a stock 5.3L make 355 hp? This is a fair question, given the fact that it was rated at just 285 hp (275 for the early versions). Do we not know what we are doing? ... Read More »
