# Question: What Is A Deck Height?

## How do you measure the height of a deck?

How is it measured?Rotate the crankshaft so the piston is at TDC.Position the calipers on the deck surface (jaws up).Expand the calipers until the depth rod contacts the piston deck.

The measurement is the deck clearance.May 25, 2018.

## What is the deck height of a big-block Chevy?

9.800 inchesStandard big-block deck height is 9.800 inches from the crank centerline to the deck surface, and tall-deck blocks like this one measure 10.200 inches.

## How do you measure the height of a 351W deck?

By definition, the deck height is measured from the centerline of the crankshaft to the deck. So you need to rig up something that marks the crank centerline that you can measure against. The makers of your stroker kit should know about your specified deck height, and use the correct height piston.

## How do you calculate the height of a piston on a deck?

First, divide the stroke by two and add that to the rod length: 3.75 / 2 = 1.875, and 1.875 + 6.00 = 7.875. Next, subtract that answer from the deck height: 9.00 7.875 = 1.125. So the answer is that the piston compression height should be 1.125 inches.

## How big is a 454 bored 30 over?

a . 030 over 454 gives you approximately 460 cubes.

## Why is deck height important?

Deck height dictates many engine dimensions. It limits stroke, rod length, and piston compression height. This last dimension is a critical part of the rotating assembly equation and is defined as the distance from the wrist pin centerline to the piston deck.

## What is deck height on an engine block?

Engine block deck height is the distance from the centerline of the main bearing bore to the flat surface of the block where the heads bolt on.

## How is BBC deck height measured?

1/2 stroke + Pin Height + Rod Length= Deck Height. The deck height is the distance from the centerline of the main bores to the top of the block.

## Is a 502 a tall deck?

502 is a short deck like a your 454 but can be poked and stroked much further all the way to 4.625 x 4.375 = 588ci.

## What is a tall deck engine?

– Tall deck blocks use a special intake manifold and distributor to allow for the additional height. Other than that many parts can be the same as a standard deck. – The ‘stroke’ of a standard and a ‘tall-deck’ 427 are the same, only difference is the piston.

## How far should a deck be below a door?

There’s no magic number, but I would recommend a minimum of 2 in. from the top of the decking to the bottom of the patio door threshold. I opted for 3-1/2 in. Many doors have a sill or threshold that needs to be supported, so don’t forget to install a kick plate under the door.
