New Products for Modern V8 Engines
Modern V8 engines such as the GM LSX, Ford Modular and Chrysler Gen III Hemi offer many advantages for engine builders, and may as a group displace the small block Chevy engine as the number one most rebuilt engine.
By Brendan Baker
The numbers aren’t there yet, but engine builders and suppliers are taking notice of the new V8s. What has taken so long? For one, the new engines are more expensive and more complex. Some shops do not have the capability or expertise to work on them just yet, but more and more shops do.
One of the drawbacks of the LS, said one supplier, is that they are very good right out of the box. The engines are lighter and produce a lot of power without having to make any modifications, and there’s really no comparison to the SBC, which would require a lot more work for the same power.
The Ford Modular engine series has been around for some time and has not until recently begun to live up to its potential. Many manufacturers and enthusiasts are clamoring over the new 5.0L Coyote engine that is featured in the 2011 Ford Mustang GT.
Ford’s new four-cam, 32-valve, all-aluminum 5.0L V8 has been a huge hit, and aftermarket companies are starting to offer more parts for this engine. The automotive press has been raving about the engine, saying that it’s a “major step for Ford” and that it is the “best engine ever produced” by the blue oval. Car and Driver said it makes the Camaro SS “sound like a pickup truck,” in a recent review of the powerplant.
The Gen III Hemi also has a load of potential, some of which was seen in a recent Engine Masters Challenge where the Hemis showed very strong numbers with relatively mild builds. While there are arguably fewer aftermarket parts available for the 5.7L and 6.1L than the other new V8s, the engines have gained traction among Mopar loyalists and the muscle car market.
With enthusiast demand for these engines driving development, more and more aftermarket companies will be getting into the act and building parts for one or in some cases all three brands. And like the SBC when it came to prominence, the LS has proven to be a popular choice for applications from sand buggies to drift car engine swaps, and will be finding its way into your shop soon.
We surveyed suppliers and the following are some of the latest parts available for the modern V8 mills:
Brodix has a durable replacement for the LS-style cylinder heads with the introduction of the “BR” small block series. The BR 7 is an out-of-the-box version that comes standard with 71cc combustion chambers, bowls blended, and intake ports matched. The STS BR 7 is a 100 percent CNC ported version that flows over 375 cfm. The BR 7 and the STS BR 7 both utilize a 12° valve angle and 2.204 /1.614 valve combination.
The STS BR 7 273 flows over 415 cfm with a 71cc combustion chamber and 2.250/1.614 valves. The BR 7 series heads accept all standard LS components and share all of the typical Brodix features including easily repairable A-356 virgin aluminum alloy and strongest deck surface.

In February, 2010, Lunati unveiled six new Pro Series stroker crankshafts for the LS7 with stroke lengths of 4.325˝ to 4.625˝. This year they have topped off the range by adding four more. The stroke lengths of these new crankshafts are: 4.000˝; 4.125˝; 4.185˝; and 4.250˝.
Lunati also has introduced ten stroker cranks for LS1 engines. Both series of cranks (LS1 and LS7) encompass stroke lengths of 4.000˝ to 4.625˝ and feature conventional 2.559˝ main bearing journals and 2.100˝ rod bearing journals. OEM rod lengths of 6.125˝ are recommended on strokes from 4.000˝ to 4.185˝, but on the remaining longer strokes, from 4.250˝ to 4.625˝, Lunati recommends 6.300˝ connecting rods for a better stroke-to-rod ratio.
In addition, Lunati offers custom grinds to any dimension within this stroke range.
Custom grinds can be obtained with either standard crank pins (2.100˝) or with larger big-block-style pins (2.200˝), which adds durability to engines with power adders.
Using American-made premium 4340 steel forgings these cranks are capable of handling 1,500-plus horsepower. They are endowed with micro-polished and lightened connecting rod journals to reduce rotating mass, micro-polished and gun-drilled main journals to reduce overall mass, special counterweight profiles to direct oil to the bearings and reduce windage, and Lunati’s exclusive finite detailing, profiling, and pulse-plasma nitriding processes.The latter provides consistent journal surface finish without affecting core hardness.

Elgin Industries has introduced a new line of thick-wall one-piece rods that enable performance engine builders to achieve significantly higher dynamic loads and rpm.
The new Pro-Stock push rods are manufactured from aircraft-quality 4130 seamless steel tube with wall thicknesses of 0.137˝ (3/8˝ diameter rods) and 0.106˝ (5/16˝ diameter rods), providing a stiff tubular-constructed push rod. By comparison, conventional one-piece performance push rods feature 0.080˝ wall thickness.
In addition to increased wall thicknesses, these new parts offer an array of advanced construction, machining and other enhancements to maximize wear resistance, strength and performance: radius ends are hard-turned following heat treatment for superior surface-shape profile tolerance and finish; 220-degree radius ends for increased rocker travel; fully hardened within Elgin’s world-class heat-treat facilities for extreme wear resistance and strength; centerless ground for geometric precision; corrosion-resistant black oxide coating formulated for performance applications.
