Watch This 427 FE High Riser Crank Out 670hp On The Dyno – This Thing Sounds Grand!

We’ve told you about the 427 FE high riser engine a bunch here at BangShift over the years. One of the meanest versions of the venerable engine, it powered Ford to make race wins on circle tracks and the high riser is still a force to be reckoned with on the drag strip. In this video from Survival Motorsports we see a Barry Rabotnik built high riser crank out 670hp on the dyno. The stats of the engine were not published with the video so we do not know stuff like displacement, compression ratio, or camshaft specs, but we do know from the video’s title that the sucker makes nearly 700hp. This engine in a stick shifted, light drag car would be pretty brutal and awesome.

High riser heads are factory parts insomuch as they were made and sold by Ford but they were never installed on factory mass produced cars. These were race car heads, plain and simple and they carried a factory part number because they had to for racing in the series and classes that they were designed to be used in.

The heads were so named because they carried the tallest intake ports of any FE heads. The dimensions of the intake ports are 2.72 x 1.34″. The heads also contained larger valves measuring 2.195 and 1.73″ respectively. They were obviously there to handle the increased air volume from the larger ports. Because of the head design a unique intake manifold was needed. No factory intake fits high riser heads except for the dedicated high riser pieces developed specifically for them. The idea in stretching the port and making the intake taller was to get a better entry angle for air and fuel into the combustion chamber. It worked as demonstrated by the power numbers in this video.

This is a really cool piece and you get to hear it make a couple of rips on the dyno. A low RPM pull or two and then a couple of romper stompers.

Tre5 Customs OBS Chevy Feature: Red On Red On Red On Red…

Image
This cool truck feature from Tre5 Customs is an OBS that just about everyone can relate to. Yes, the fit and finish is high level, the chassis is rad, and the LS swap is on point, but overall this truck is still identifiable as an OBS, with only one body modification! It still has door handles, features some sport mirrors, and other than a welded in roll pan out back doesn’t have any body mods. It’s just as the general intended, only smoother and prettier. Check out the details in the video below. As we’ve said before, the guys at Tre5 build some pretty cool trucks, and I always like watching their feature videos that come along when a project is ready to get delivered to the owner. These aren’t super sexy videos that make you ooh and aah over the truck but never actually tell you what is in it and under it, these are videos that really show you the cool stuff that went into these builds! We’re talking about the details and info that real enthusiasts want. And while these trucks are t

Check Out This 6×6 Engesa EE-25 Army Truck And It’s Freaky Boomerang Rear Suspension In Action

Image
Army trucks, we love them. Why? Well for the same reason we love functional hot rods that are lacking in amenities but are heavy in ass kicking ability. No matter the country of origin you are typically not going to find a lot of cushy stuff in an army truck, especially a large one. They are loaded full of ability, though and that’s exactly what caught our eye when it comes to this Brazilian 6×6 Engesa EE-25 and its awesome Boomerang rear axle. The truck uses a walking beam style layout but it can articulate in some incredible ways to keep the rears planted while the rest of the chassis rises to some pretty steel angles. Quoting a story on the rear suspension: The suspension of the EE-25 utilizes live axles and leaf springs, the rear suspension having a conspicuous “Engasa Boomerang” walking beam, a feature seen on several other Engesa 6-wheeled military vehicles. This suspension articulates, allowing the EE-25 to traverse large undulations with greatly increased traction, handling,

FAST LSXR INTAKE TEST-IS IT WORTH $1000? HOW MUCH HP DOES IT ADD? LSXR VS CHEAP, JUNKYARD TRUCK INTAKE

Image
One thing that sucks about modern EFI engines like the LS, LT, Mod Motors, And HEMIs is that aftermarket intake manifolds for them tend to be really expensive. It’s understandable as there is a lot of technology going on in there and the manufacturing is way different than the typical cast aluminum intake manifold. Some of these intakes cost around $600 but some are closer to $1,500. The question is whether or not they are worth it. In truth, we know they work, and work well, but whether it is worth the money or not is going to be up to you. In this test video from Richard Holdener, who has tested more LS intake manifolds than anyone on earth, he’ll show the real results of testing this hopped-up 5.3 with a stock truck intake and a FAST LSXr. Video Description: LOW-BUCK, CHEAP, JUNKYARD TRUCK INTAKE VS BIG BUCKS FAST LSXR! HOW MUCH POWER IS THE FAST LSXR INTAKE WORTH ON MY LS? SHOULD I BUY IT FOR MY STOCK 4.8L OR 5.3L? FAST VS TRUCK INTAKE-WHO WINS? HOW MUCH POWER IS THE INTAKE UPGRA
