    Forged Internals. If you plan on adding more asphalt-chewing power to your Mustang you will want to consider replacing the stock engine internals with a forged upgrade. Scat Street Strip Rotation Assembly gives you everything you need to ensure your 4.6L V8 can withstand the abuse of making passes down the drag strip. Perfect for forced induction applications with a 9.0:1 compression ratio this Scat Stroker Kit will punch out your 281 cubic inch V8 to a more respectable 300 cubic inches.

    Kit Includes. Maximize the displacement of your engine with a cubic inch-enhancing stroker kit that includes a 4340 forged steel crankshaft, 4340 forged H-Beam connecting rods with 7/16" cap screws, forged dish top pistons as well as rings and main & rod bearings.

    Compression Ratio. The Scat Stroker Kit will allow for different compression ratios depending on the heads installed. Example: 9.0:1 with 51cc heads.

    Serious Upgrade. Replacing the rotating assembly is a serious job that requires a wide range of tools, space, and knowledge. Without a decent mechanical background, it is best recommended to take this to a shop for install.

    Application. This Scat Street-Strip Rotating Assembly Kit is designed to fit 2005-2009 Mustangs equipped with the modular 4.6L 3-valve V8 engine - including the GT and Bullitt models.

    Will this make my gt slower if kept n/a

    Roushrs1

    • The Scat 300 ci Street Strip Rotating Assembly will up the horsepower of the car since it will create a larger displacement engine. You can keep the car NA or apply forced induction. Regardless, you will see an increase in power.

    Do i need to bore out my heads with this set up?

    JonathanB

    • You will not need to bore the heads when you install this Scat 300 CI rotating assembly. Head boring is not normally done unless you are getting a high top piston. since this is a standard size bore, nothing will need to be done machine wise other than the standard honing. The only time you will need to make modifications is when you have an over-sized piston, in which the block will need to be machined and not the heads.

    Does this fit a 2010 gt because it has the same motor why they say 05 to 09

    Stanggang

    • Unfortunately, due to the model design change in 2010, even though it has the same engine and may fit, we are not able to guarantee fitment of this rotating assembly for that year car.
