The most tedious and time consuming part of building any engine is the short block. It requires a lot of machining work that requires expensive and specialized equipment, a lot of pre-fitting parts, and don’t forget a lot of gapping piston rings.
That’s why purchasing a complete short block is a popular option for racers and hot rodders. The tough part is done and you still get the option of choosing your own cylinder head, camshaft, induction and other considerations to make the engine fit your needs. If you are a Mustang owner running a Modular 4.6 Ford engine, Ford now has a great short block available for your next engine build–they call it the Aluminator 46X 5.0.
You’ve probably already guessed that the 5.0 designation means the block is bored and stroked to bring the normally 281 cubic inch engine up to 302 cubic inches. The short block is completely hand assembled using an Eagle forged crank, Eagle 5.85 inch rods and Mahle 90 mm forged pistons.
Ford says the short black can easily handle 700-plus horsepower, either naturally aspirated or via power adders. The block will work with either Ford’s two-, three- and four-valve cylinder heads.
Ford has even run several variations of the completed engine on the dyno. With factory Ford PI two-valve heads and a factory intake, they got 369 horsepower and 393 ft/lbs of torque. With a three-valve head and a Ford Racing intake manifold power production jumped up to 440 and 435, and with a supercharger installed power went all the way up to 748 and 667, respectively.
There’s lots more information on this new short block in the video below, and you can also check out the Ford Racing website for more information here.
Holley introduced the original Dominator in 1969 when it was developed for NASCAR racing. It has been refined over the years, and now it’s receiving its biggest change ever. Holley has just taken the wraps off of the Gen 3 Ultra Dominator featuring an all new main body, all new calibrations, high capacity fuel bowls, and new larger sizes. They come in a variety of new sizes from 950 CFM, 1350, 1425, all the way up to 1475 CFM. They are also available in the standard 1050, 1150 & 1250 CFMs racers have come to expect. One of the big improvements in flow comes from a main body that’s 5/16″ taller which allows for larger radius air entries that have been optimized on computational fluid dynamics (CFD) software. Each Gen 3 Ultra Dominator also receives a new calibration optimized for today’s larger engines and newest fuels and are also dyno & track tested to ensure performance.
Holley says the venturii throat to throttle bore section is fully machined for predictable and repeatable performance and a new idle-bypass valve was incorporated to maintain proper throttle plate to transfer slot relationship on engines with radical camshafts. Fuel enters the main body through a set of boosters with billet 12-hole inserts for superior atomization and crisp throttle response. A new modified-skirt booster is used on the larger CFM models to maintain a strong fuel signal. To keep up with today’s electronics, a throttle position sensor mount is featured on every main body and a sensor is available separately. Integrated air scoop mounting bosses are also new to the Gen 3 main body.
The linkage is all external and tuning is easier than ever with threaded secondary links to adjust from 1:1 to soft progressive. Curb idle screws are knurled for quick adjustments without a screwdriver. Holley’s popular HP fuel bowls are carried over to this line with -8 O-ring inlets, fuel level sight windows, 20% higher fuel capacity, drain plugs, internal baffling, and more. The Gen 3 Ultra Dominators are available in a tumble polished finish with Red™ or Black™ metering blocks or hard anodized Hard Core Gray™ main body with Black™ metering blocks.
You can see more about Holley’s new carbs on their Gen 3 Ultra Dominator Page.
The new Corvette is just now hitting showroom floors. It is a technological advancement as large as any the Corvette has made from one generation to the next–and upper tier parts manufacturers are already producing components to improve its performance.
Not the least of which is Kooks Headers and Exhaust which has already designed headers, an X-pipe and cat-back exhaust system to work with the all new LT1 engine and Corvette chassis.
Kooks says they new exhaust is constructed using CNC mandrel bent stainless steel tubing and 3/8-inch hand ported flanges. Also included with the kit will be Cometic multi-layer steel exhaust gaskets, ARP header bolts and Torca clamps.
Just by itself, Kooks says their exhaust system is worth 39 horsepower and 38 lb/ft or torque at the rear wheels, and they’ve provided this video and dyno chart to prove it. We can’t wait to see what else other manufacturers have in store for this great car.
The annual SEMA show in Las Vegas is always a great place to get a first look at great custom and modified cars. But Ford is definitely taking things to the extreme by bringing an incredible 57 vehicles to the 2013 edition of the show.
Many of the vehicles on display will be vans showcasing Ford’s new Transit Connect–they are actually calling it “Vandemonium”–as well as the redesigned Fiesta. But at least three will be Mustangs, even though you wouldn’t think there would be much excitement about the final year of the current generation before we are able to get out hands on the all-new 2015 model. But what we’ve seen looks pretty phenomenal.
Take, for example, the black Mustang build by Hollywood Hot Rods. Besides hand-formed aluminum body mods, this black beauty is said to be pushing 750 horsepower thanks to a supercharger and methanol injection.
Then there’s also the Yellow Jacket by Vortech boasting an also impressive 605 horsepower and 473 lb/ft of torque with just 7.5 pounds of boost. And don’t forget to check out the red piece of art from Nitto. Ford plans to unveil plenty more of the vehicles in the days before SEMA, so check out the gallery below and check back for more soon.
This may be the most accurate rendering of Fords new 2015 Mustang yet, thanks to Mustang6g.com.
The website says that the renderings are created from leaked CAD images and spy photos. Many Mustang fans were worried the next-generation car would look too much like a two-door Fusion based on previous renderings and spy photos, but if the car looks anything like this that won’t be a problem.
Mustang6g says that while the catfish grille front-end styling has already been established, but the big surprises are at the rear of the car. They say the unique louvered taillights as well as the reverse light centered in the lower portion of the rear bumper are accurate. There’s also a more swept look to the fastback glass, and Mustang6g says that there will also be a double-bubble design element on the roof but it is too slight to show up well in the renderings.
So let us know, if these renderings turn out to be accurate, do you think the sixth generation Mustang will be a hit?
Everything is better when it’s free. Heck, even broccoli is better when it is free–and covered in cheese.
But this beats the pants off broccoli. Reher-Morrison Racing Engines has donated one of its 1,200 horsepower big block race engines to be given away at the 2013 PRI trade show in December to benefit Victory Junction.
OK, so technically the engine isn’t free. You have to buy a raffle ticket, but all proceeds (that’s 100%) go to Victory Junction, which is an incredibly worthy cause. Victory Junction is a camp in Randleman, NC, for children from six to 16 years old with chronic medical conditions that was founded by Kyle and Pattie Petty in honor of their son, Adam.
Reher-Morrison’s big block Chevy race engine has been dyno tuned and tests out at 1,200 horsepower and 880 ft/lbs or torque. If you were to buy one yourself you would have to pony up approximately $24,000, so the equivalent of your lunch money for a handful of raffle tickets isn’t a bad deal. You can buy a ticket here or at the PRI show at the Sunnen Engine Charity Sweepstakes booth on Machinery Row.

It hasn’t even made a lap in real competition yet, but Ford’s new Ecoboost V6 race engine is already making news.
Ford, along with considerable help from Roush Yates Engines, developed their Ecoboost engine for racing with a revamped twin-turbo system (but kept the stock block and heads). Next year it will be used by Michael Shank Racing (MSR) in the new TUDOR United SportsCar Championship in the Prototype class.
But along the way, Ford, MSR and driver Colin Braun thought they’d smash a few records. Braun recorded a lap around Daytona at 222.971 mph, destroying the existing record of 210.364 mph set by Bill Elliott driving a Ford Thunderbird in NASCAR qualifying all the way back in 1987.
The Ecoboost also broke the FIA World Records for a standing 10 kilometer run and a 10 mile run (202.438 mph and 210.018 mph, respectively) but those records are still waiting certification by the FIA.
We can’t wait to see how this new motor fares in competition, but in the meantime Ford has kindly provided us with the following video of their record-breaking day.
There’s really no need for words here, so we’ll just leave you with this awesome video.
Things turned bad pretty quickly for these two Porsche drivers at the October American LeMans Series race at Virginia International Raceway. Thankfully, despite the fact that one of the Porsches actually wound up on top of the tire barrier, both drivers were able to walk away.
By the way, keep an eye on the camera man who stands steady when a couple of tons of German sheetmetal come sliding his way at a high rate of speed.
Here’s the video:
