Engine Masters - Season 8 (2023)

How much airflow does your throttle body need to provide? That's what we're here to answer this time on Engine Masters, as we compare 90mm and 105mm forward-facing throttle bodies against one another and then to 2000 cfm worth of top-mounted, dual quad-style throttle bodies. These will all sit atop a fuel-injected 442ci LS7 mill pumping out around 700 hp. How much airflow is enough for this power level? We're about to find out.

Call it a velocity stack, a radiused entry, or even a salad bowl, the bellmouth is designed to direct and smooth the airflow into the throttle body, creating a more efficient airflow. But does it make power? We'll be answering that very question for both N/A and supercharged versions of our 363ci small-block Ford.

Precise and scientific or unrefined and ham-fisted? Despite the reputations each of these injection styles carry, does either really make a difference when it comes to overall power? We're exploring that question as well as the tunability, what it takes to make the switch, and all of the pros and cons that come along with each. Come learn the truth about what you really need, right here on Engine Masters.

Cam specs are cam specs, right? WRONG!. This time, we show you how three seemingly identical cams can behave very differently. It's called cam lobe intensity, and it's all about the shape of the lobe between the base circle and the nose. So what's the difference between a standard, a high-intensity, and a low-shock cam? Which one is right for you? Find out on this time on Engine Masters.

Can any one type of spark plug make more power than the next? What about the ones with fancy metal tips or extra ground straps? What if you gap them bigger or smaller? We'll answer all these questions and share as many tips and tricks as you can handle. If you have a gas motor of any size, this time on Engine Masters has something for you.
