Richard is back at it with some super top secret, never before tested, Accufab 5.0 intake testing. We love the guys at Accufab and their creativity, so it is no surprise that something like this exists from those guys. In the video below you will see Richard testing this bad boy on the dyno, along with a stock vs roller rockers upgrade to see if it makes a difference and if so by how much. Check it out below.

Vice Grip Garage’s Chopped Top 1935 Ford Truck is Back: Dirthead Dave And Derek Work On Engine, Transmission, Rear Suspension REMOVAL Because IT’S SO BAD!

Chad Reynolds — Thu, 20 Jun 2024 23:15:21 +0000

Okay gang, it’s time to start working on this thing. Derek and Dave decided to get their thrash on to see how finished they can get this thing for Derek to take it to the Nashville stop on Hot Rod’s Power Tour. Derek called in Dirthead Dave Chappelle for his expertise on the air ride and such, but also because Dave is committed to making this thing be a Ford again instead of having a Mopar engine up front and a bunch of other hodgepodge parts.

I love the look of this thing, but it sure doesn’t work well. It’s got a hodgepodge of parts in it and now it is time for Derek to get it fixed up the right way so it can be driven more. You are going to dig where it is going and the thrash that they are putting into it in order to get it ready to rock at Hot Rod’s Power Tour.

Here’s the video from Derek, and there is more video coming from Dave as well!

GEN 2 LT1-THE OTHER GUYS SMALL BLOCK-HOW MUCH ARE PORTED HEADS & TPIS ZZ409 CAM WORTH ON THE LT1?

Chad Reynolds — Sat, 15 Jun 2024 10:29:48 +0000

I’ve got a Gen 2 LT1 in a 1956 Chevy, and it has always been a fun engine. It’s mostly stock, but when we put a stand alone EFI on it and significantly improved ignition, we were able to squeeze a surprising amount of extra power out of it. So when I saw Richard doing more testing on his LT1 I figured there was some good stuff to learn. Check out the video below and see what you think.

Video Description:

HOW MUCH POWER DID THE GEN 2 LT1 REALLY MAKE? HOW MUCH POWER ARE PORTED HEADS WORTH ON AN LT1? HOW MCH POWER IS A CAM WORTH ON AN LT1? IS THE LT1 BETTER THAN THE LS? WHAT HAPPENS WHEN YOU REPLACE THE STOCK LT1 HEADS AND CAM WITH PORTED HEADS AND AN AFTER MARKET CAM? CHECK OUT THIS VIDEO THAT FEATURED PERFORMANCE MODS ON THE GEN 2 LT1. IN THIS ONGOING SERIES, THE LT1 RECEIVED HAND-PORTED LT1 HEADS (STOCK VALVE SIZES) AND A TPIS ZZ409 CAM. CHECK OUT THE POWER GAINS OFFERED BY REPLACING THE STOCK COMPONENTS WITH THE PORTED HEADS AND TPIS CAM. THE QUESTION IS-WAS IT ENOUGH?

Carb Tuning 101: Powell Machine Talks Holley Carburetor Tuning For Maximum Power. Learn How Your Holley Works.

Chad Reynolds — Wed, 05 Jun 2024 10:13:44 +0000

We’re fans of the tech that is shared by the Powell Machine crew, and the two videos below are no different. If you are looking for Holley carburetor tuning info, then these Holley Carburetor Tuning 101 videos should be right up your alley. If you don’t understand how a carburetor works, with regards to idle circuits, main circuits, power valves, and more, then you want to watch this.

For an automotive part that is often referred to as super simple and old school tech, there are really a bunch of cool tech going on inside them. I’ve owned lots of carbureted cars, and several that are fuel injected. And while I love my Holley EFI, I still totally dig my Holley carburetors too.

Video Description:

The first video talks about the idle circuits and main circuit functions of a traditional Holley Carburetor, and how to tune them.

Polishing Turds Season 2: Part 7 – The Right Valve Job For Cody’s ProCharged 360 Cubic Inch Small Block, And How A Valve Job Effects Flow

Chad Reynolds — Tue, 04 Jun 2024 09:28:45 +0000

In the seventh episode of this new Polishing Turds engine project, Pete is going to be performing the valve job on this little supercharged small-block so it will be able to make big consistent power. He’s also going to explain how the valve job effects flow, and what the angles mean and why they matter. This is just one part of the whole makeover on this already powerful small block, but it’s going to be way better when it is all done. Check it out.

In the first season of Polishing Turds on the Real Good At Doin’ Stuff HED YouTube channel there was another small block that got the love and made considerably more power afterwards. In this new season, our pal Cody is getting the Polishing Turds treatment for his 360 cubic inch 23 degree headed small block. It has just over 9:1 compression, and is force fed boost by an F1X ProCharger. This new season of not only interesting to me because it’s Cody, but also because this combo is very similar to our own 400 inch F1X ProCharged small block.

6.0L LS2 VS 6.2L LS3-WHICH ONE MAKES MORE HP STOCK, MINOR MODS THEN ALL THE MODS? FULL DYNO RESULTS

Chad Reynolds — Mon, 27 May 2024 10:25:20 +0000

There’s no replacement for displacement. That’s the age old saying and we know that there isn’t much that compares with going bigger in search of more power. But how much bigger is worth what? I mean, should you worry about every single inch, or is it not worth it until you go up in size by some certain amount? Is just over 12 cubic inches worth much? Is a 6.0 good enough or should you go with a 6.2? Richard is going to cover those questions and answers in the video below, so check it out.

Video Description:

IS BIGGER REALLY BETTER? HOW MUCH MORE POWER DOES THE LS3 MAKE COMPARED TO THE LS2? ARE THE REC-PORT 821 LS3 HEADS REALLY BETTER THAN THE CATHEDRAL-PORT 243 LS2 HEADS? WHICH ONE HAS HIGHER COMPRESSION? WHICH ONE HAS A BETTER INTAKE MANIFOLD? WHICH ONE MAKES MORE TORQUE? WHAT HAPPENS WHEN YOU START CHANGING CAMS, HEADS OR INTAKES? CHECK OUT THIS DYNO COMPARISON BETWEEN A FACTORY LS2 AND FACTORY LS3 RUN IN STOCK TRIM, THEN AFTER MINOR MODS, THEN AGAIN AFTER EVEN MORE MODIFICATIONS! HOW DOES THE 6.0L COMPARE TO THE BIGGER 6.2L?

Powell Machine Tech Talk: We gotta talk about this torque plate deal….. Does It Really Matter?

Chad Reynolds — Tue, 21 May 2024 14:49:26 +0000

The internet is a wonderful thing… but it is also a giant pain in the ass. And in its defense, it has just become a vehicle for people to rant and rave about things that sometimes just make no sense. In the horsepower world, the problem with the internet is that a huge percentage of people seem to find themselves discussing engines and engine components with “ideals” in mind. By ideals I mean the absolute theoretical perfect circumstances for an “ideal” engine combination that is going to make the most power per cubic inch possible. I’m talking Formula One levels of performance. Unfortunately, so many people get into discussions like this that it becomes intimidating for the average hot rodder to build an engine. For example, I talk to someone at least once per week who wants to build an LS engine that makes 400-450 horsepower who thinks they need to send stuff off to the machine shop for custom work and thousands of dollars worth of aftermarket parts, when off the shelf stuff will get them there with their junkyard engine.

And I’m not saying nobody should buy aftermarket parts, but why not save your money on the 400 horsepower combo, so you have it to spend on the 1,000 horsepower combo? Or so you can get the 6-speed swap from American Powertrain that you have been wanting?

I know some great engine builders. I love Derek at L&R Engines in SoCal. He’s done machine work on several engines for me and is a great guy who does what is right for his customers. Peter Harrell at Harrell Engine and Dyno is a close friend who does amazing work. And I’m a big fan of Daniel’s videos from Powell Machine. The thing that all three of these guys have in common, and that I hear from tons of other great engine builders, is that not every trick in the book is necessary on every engine. In fact, they aren’t necessary on most engines.

I could go down a giant rabbit hole on all kinds of levels, but this video here is in response to people talking about Torque Plates for honing. Yes they are good. No they are not needed on every application.

Here’s why.
