The stock deck clearance of a 454 engine, specifically the Chevrolet Big Block 454, typically ranges from about 0.020 to 0.060 inches. This measurement refers to the distance from the top of the cylinder block to the top of the piston when it is at its highest point (top dead center). Variations in deck height can occur due to manufacturing tolerances or modifications, so it's important to measure for specific applications. Proper deck clearance is crucial for optimizing compression and engine performance.

How do you tell if my 454 is a tall deck block or not?
To determine if your 454 engine is a tall deck block, measure the height of the block from the crankshaft centerline to the top of the deck. A standard deck height for a 454 is about 9.8 inches, while a tall deck block measures approximately 10.2 inches. Additionally, you can check the casting numbers on the block; tall deck blocks typically have specific casting numbers that identify them as such.
What is the stock stroke length on a 454 crankshaft from a truck block with a height of 10.2. or were there any stock 4.250 stroke crankshafts produced from chevy.?
Have not seen a 454 with a 10.2 deck. have seen a 427& 366 10.2 truck blocks that have a 3.76 stroke crank, 454 should be a 4.00 stroke crank. The cranks are the same in a short deck 8.2 and a tall deck 10.2 the difference is made up in piston height and # of rings on piston. Not seen a stock 4.250 stroke crankshafts.
CAN HEads off a stock 454 engine give a stock 305 engine horse power and around how much?
Heads off a 454 engine will not fit a 305 engine A 454 is a big block and a 305 is a small block. Even if they did fit it would probably run poorly due to low compression because the combustion chambers on the the 454 heads are larger than the ones on the 305 heads

What is the difference between a 454 Chevy truck engine and a 454 Chevy car engine?
I don't think there's a difference, I base my answer on we removed a 454 from a 82 Chevy Suburban on the engine under the timing cover embossed on the front of the engine, "Hi-Perf, Pass. Hope this helps. There's a difference...... Light Truck and Passenger Car engines are the same. Medium and Heavy Duty GM Trucks use a tall deck block. The distance from the crank center line to the top of the cylinders is .4" taller than the short deck block. The block is beefier and the cam is raised. Most parts are interchangeable and one will bolt in place of the other. The tall deck block is taller and wider than the short deck so there are clearance issues when installing in a car. They are commonly used in drag racing because the thicker cylinder walls and the raised cam allow engine builders to bore the cylinders bigger and install longer stroke cranks then can be done on a short deck block.
