One of the most common valvetrain upgrades for pushrod-style engines is roller rocker arms, which are often said to increase horsepower through reducing friction. But is it true? Find out on this episode of Engine Masters.

We test the long-standing internet theory that too big of an intake port kills bottom-end torque. Watch us take the mildest of 408 Ford small-blocks and try to make the torque curve dance.

We test a whopping 19 different combinations of filter sizes and styles, including paper elements, K&N filters, stock housings, dual-snorkle housings, velocity stacks, filtered lids and way more.

Find out if you can stuff 25 psi of boost into a cast-piston, stock-crank short-block and have it live. We strap a ProCharger centrifugal supercharger to a bone-stock Chevy 350 bottom end.

This time on Engine Masters, hosts David Freiburger, Steve Dulcich, and Steve Brulé show you how to install and tune a Weiand 6-71 blower and dual 750-cfm double pumpers on a budget 350ci Chevy short-block.

On this episode, we explore an ancient scenario but still one of the most frequent tech questions we are asked: What budget bolt-ons can be used on a stock small-block Chevy 5.7 to get more horsepower?

It's Roadkill meets Engine Masters. On this episode, host David Freiburger pulls the engine out of the Rotsun 240Z and stabs it on the engine dyno at Westech Performance Group. The result is mind blowing, but we're not sure what's more surprising, the power or the fact that it never blew up.

We deliver the goods many viewers have asked for as we test the power of straight dual exhaust with no crossover pipe versus using an H-pipe versus an X-pipe.

This episode reinforces the fact that Steve Dulcich is not just the guy in the back of the dyno room, he's a legit engine master. You won't question that after you see his homegrown porting job.

Usually on this show, we are all about making more horsepower, but on this episode, we are trying to kill horsepower! We bolt four different types of cooling fans onto our 350 small-block Chevy, all with different designs and material.

David Freiburger explains cam lift, duration, love separation angle and installed centerline.
