What does "decking the Block" mean on my engine?
Engine Block Decking Defined The term decking is used for the machine process that trues the head-gasket surface of the block. Most of the time, the objective of decking is to end up with a flat surface cut that is parallel with the center line of the crankshaft and at the correct angle to the cylinder bores.
How much can you deck a block by?
The blocks are commonly uniform in length, being 14-1/2” for joists spaced at 16” centers, 10-1/2” for 12” centers, and 22-1/2” for 24” centers. The 2018 International Building Code (IRC) Section 502.7 requires deck joists to be blocked with 2-by material the same depth as the joists at the ends to prevent rotation.
How do you use deck blocks?
- Strapping is the use of a 1×3 or greater board across the underside of joists every 4 to 6 feet from outside joist to outside joist. ...
- Blocking is short lengths of solid blocks cut from joist material and attached between joists. ...
- Cross bracing deck joists is done using 2×2 material mitered at each end and fastened to form an X between joists. ...
What is better a closed deck block or open deck?
Yes a closed deck block is stronger than an open deck block. There are more material and more structural integrity, but with modern designs, materials, and manufacturing methods, the strength difference between the two isn’t as drastic as it once was. Many modern engines use a closed deck design and many of them also use an open deck.
Is decking a block necessary?
If the block is NOT square it's a no brainer, gotta deck it. If it is square and it passes a flat test using a straight edge and a feeler gauge there is no "normal" reason to deck it at all. If you want to get fancy and go for zero deck height (not a bad thing) or some other "race ready" reason, then deck it.Oct 8, 2004

How do engine blocks work?
The engine block - also known as a cylinder block - contains all of the major components that make up the bottom end of a motor. This is where the crankshaft spins, and the pistons move up and down in the cylinder bores, fired by the fuel combusting. On some engine designs, it also holds the camshaft.

What is a pier block?
A deck pier block is in many ways just a simplified version of a “precast foundation”, a foundation type recognized by building codes. They’re subject to all of the same requirements as a typical footing, regardless of not being cast-in-place. They must have a sufficient bearing area (the area of the block that sits on the earth) and be a minimum of 12-inches below grade, or below the local frost depth. They cannot, however, be simply placed at grade level.#N#The connection of the deck support post to the blocks is not consistently regulated throughout the country. Some regions with high winds and concerns of uplift forces may not approve them, as there is typically no physical connection between the post and block. For lateral forces, like a post getting hit with a lawn mower, we don’t want the post kicked out. Therefore, building codes require lateral restraint at the base of a post. While pier blocks commonly have protruding concrete lugs that surround the post, there is only opinion as to whether they are of sufficient strength.#N#The small bearing area of pier blocks is limited in supporting much load. Therefore, beam and joist spans must be limited and more blocks must be used over typical construction. Overall, pier blocks are best suited for low- or ground-level decks, where smaller framing materials are common and additional posts and blocks are not an eyesore. Uplift and lateral forces on the posts are also of less concern in ground-level decks.
How deep should a block be for frost?

What is a block used for on a deck?
Most deck builders use scrap or unusable joist boards to cut into blocks for use at mid-span or 8’ spacing between beams. Blocking is also frequently used to create a frame or racetrack to support deck board designs such as picture frames, herringbone, zipper, parquet, and diamond patterns.
What is Joist Blocking in Deck Construction?
Deck joist blocking is pieces of wood cut from joist material and installed perpendicular to the joist to connect or bridge the gap between joists. The blocks are commonly uniform in length, being 14-1/2” for joists spaced at 16” centers, 10-1/2” for 12” centers, and 22-1/2” for 24” centers.

To fasten deck blocking 10d nails are commonly used. Nails have greater shear strength and screws greater pulling and holding ability. Some builders use specially designed and manufactured structural screws instead of nails to pull twisted joists against the blocks and to prevent squeaks.
How often do you need to block 2 by joists?
2-by blocks the same depth as the joists are required by the IRC at open joist ends to prevent rotation or the use of rim or band joists. Additional blocking every 8’ or less is also mandated for joists larger than 2×12. The NDS requires 2-by blocking every 8’ or less for 2×10 and 2×12 joists.
What is the IRC code for deck joists?
The 2018 International Building Code (IRC) Section 502.7 requires deck joists to be blocked with 2-by material the same depth as the joists at the ends to prevent rotation. A band or rim joist, or a header are acceptable alternatives to end blocking. Section 502.7.1 of the IRC identifies that joists greater than 2×12 require blocking at intervals of not more than 8 feet.
How many feet between end joists?
The American Wood Council’s 2015 edition of the National Design Specifications (NDS) requires 2×10 and 2×12 joists to be blocked at intervals of 8 feet or less. The NDS also requires blocking between end joists or the use of rim or band boards to prevent rotation.
How to install block between joists?
Alternating blocking is an easy way to install solid blocking between joists. Measure where the blocks are needed at both ends of the deck and snap a chalk line. Alternating block placement on either side of the line from joist to joist makes it easier to direct fasten than in from above or below.

If a few hundred pounds of timbers could fall on you and your guest, you want something that is stable. Deck blocks are good for supporting a low deck, but not something overhead. Overhead structures should be supported by permanent footings designed to support the load.
How to drain ice from a deck block?
Place about 2″ (50mm) of non-organic drain material in the hole and compact. This is to provide drainage under the deck block to minimizing heaving. The water draining away and space between the rocks provided room for the ice to form without moving the block.

Also, concrete footings require considerable amounts of soil to be excavated, whereas minimal digging is required to install deck blocks. Price.
What is deck height?
Deck height is a term that gets thrown around often when discussing engine builds but it might not be familiar to some. The deck height dimension comes from a measurement from the center of the crankshaft main bearing journal to the surface of the block. What this measurement does is lay the cornerstone of the rotating assembly’s foundation.

Why are truck blocks heavier?
This was common with the Chevrolet big-block engines where the truck blocks were heavier due to the taller deck, but they could use a longer stroke and have more displacement.

In some cases, a build might actually benefit from an engine block with a shorter deck height. McInnis explains why you might want to look at all of your options before a block is selected.
Can power adders increase deck height?
If power adders are being employed, a small increase in deck height can be a big advantage. Also, be aware of things like the availability of intake manifolds. For some deck heights, there are few choices, and for some, a custom intake will be the only option,” McInnis explains.
