      Hey, guys. Today we're gonna be taking a look at the Ford Performance 5.3-Liter Modular Stroker Shortblock. This is a 4.6-liter base modular short block that's bored to 5.3-liters and it offers a great platform for those of you out there that are looking to go with a custom-build and big modular horsepower, or you could go with a more mild and naturally aspirated setup with this block.The cool thing about this short block is that it really suits a lot of applications: naturally aspirated, supercharged, 2-valve, 3-valve or 4-valve, and this short block can work with it all. Not only does it suit a lot of applications but it also has a wide range of power possibilities too which really makes us a good option for just about anyone looking to go with a custom setup. Ford Performance has taken care of the hard part with the block and designed it in a way that makes the end result a strong and durable block that can have many jobs. It costs right about 6,200 bucks and it has $100 handling fee on top of that. And of course, the install will be a full three out of three wrenches on the difficulty meter. This short block starts off with a Boss modular block, which is a cast-iron 4.6-liter performance block. Ford Performance then added a forged Eagle 3.75-inch stroke steel crankshaft with an 8-bolt flywheel pattern, forged Eagle 5.85-inch H-beam connecting rods with floating piston pins and ARP bolts and forged aluminum pistons with a dish that's compatible with 2, 3 and 4-valve heads. Keep in mind that you will need to check piston to valve clearance depending on your camshaft. The block is also bored and stroked to 5.3-liters. And of course, it is precision internal neutral balanced, so it's ready to be finished with your heads, cams, timing set and manifold for your specific application. It even comes with a new high-pressure oil pump for you, but picking up an oil can will be something that you'll need to do. Keep in mind that this is just a short block or your bottom end, it's not a complete block. You still need to grab and assemble your top end or your heads, cam, intake and timing setup, that's why you don't see any power number outputs are power ratings from Ford on this block. The fact that this is a short block also makes nailing down power numbers a little bit difficult. Your power results will depend on how you build the short block. You have to take into consideration all the normal things. In the heads you'll use cam, intake manifold, fuel setup, any other power adders and of course your tune. All of the parts in this short block are 100% new. There are no remanufactured products here. The block is a Ford Performance part number M6010BOSS50 cast-iron block that is punched out and stroked as well. And like I said, all of the items in the bottom end are brand-new and we already talked about the specifics of those. Do make a note that 2005 to 2010 3-valve applications will need a motor mount adapter but that's noted on the product page.The block does use for bolt Mains and remember that this is a 4.6-liter base. So, you're looking at 4.6-liter heads, but you do have the choice when it comes to 2-valve, 3-valve and 4-valve heads. The Coyote heads will not be compatible with this block. You're also looking at the 4.6-liter accessories like the alternator, power steering pump, AC compressor and so forth. Once again, the install for this is going to be a full three out of three wrenches in the difficulty meter. As always, if you guys are interested in this you can always check it out more online right here at

        It eats gas but it's a good engine

        It's a good engine and I paired it with a Paxton 2200 Supercharger and it's currently pushing 528hp and 445 Torque to the wheels with only 6 pounds of boost. I'll be upgrading the pulley soon as my goal is 600hp to the wheels. I will say this though my car can fly now and when I say it moves it moves.

      Is this the original 4.6 block off the 3v or 2v

      • Hey Stanggang, This block is of its own creation to be applied to those modular 4.6 motors so its not necessarily based off any of them. But its meant for any 96-2010 mustang that came with the modular 4.6.

      Helpful (11)

      So, is the block used for this the m-6010-BOSS50? If so, good option, but where is the specification information regarding pistons, rods and crank, etc. used.? I was considering buying the aforementioned bare block, but this might be a faster/more efficient way to go.

      • This block is the same as the Boss block, but it is simply bored out. The crankshaft is forged steel with a 3.750 inch stroke. The connecting rods are forged steel H beams that are 5.850 inches. The pistons are a forged aluminum dish.

      Hello, My 2000 GT is already a fully built show/ street and strip car but my engine failed due to oil pump failure. So my question is how much horsepower is this bottom end setup built to stand? I will be putting trick flow heads with blower cams and a vortech intercooled V1 blower. And maybe a 50 shot. We are shooting for 700-800 RWHP in the car maybe 8-900 at the crank. Will she hold up? Thank you!

      • With the correct application the Ford Performance 5.3L Modular Stroker Shortblock is rated up to 800+ HP. I think she will hold up fine with what you are shooting for!

      I see this engine is built for 4.6 engines. I have an 06 3 valve. I see above where you advised to have heads port patched and to check for clearance. Which heads are recommended for this block if not factory heads?

      • Ford Performance 5.3L Modular Stroker Shortblock are designed for various cylinder head applications. This block will accommodate 2, 3 or 4 valve cylinder head configurations.

      this may be obvious but going to ask , with the high pressure oil pump does this block require a large capacity pan or can the stock on keep it fed oil? my plan is a "mild" build with possible low boost added (~500 hp and i'll be happy) for a daily also with the 8 bolt crank will i still be able to use my tr-3650? since my stock 2v has the 6 bolt crank 1 answer
