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 else can I help you with?
Will a 350 Hei Distributor fit a 454 Chevy?
yes, as long as the 454 is not a tall deck block.
Will a 454 distributor fit on a 350 Chevy motor?
As long as it is not a tall deck, it should fit fine. If it is a tall deck, you'd need to add .400" shims under the collar to fit the small block.
What is the rod length for a 454 Chevy?
Stock rod length is 6.135 inches, unless it's a tall deck engine, in which case the rods are .400 longer (6.535), tall deck engines were used in big trucks like dump trucks and were usually 427 cu in, if you're talking about a pickup truck or a car it's most likely a short deck version. Deck height on a short deck big block Chevy is 9.800" from the center line of the crankshaft to the deck, deck height on a tall deck big block Chevy is 10.200" from the center line of the crankshaft to the deck.
Can you put an HEI ignition out of a 454 into a 350?
No you cannot. Big block parts are all different then small block parts. The distributor cap WILL WORK. That answer is incorrect. Big Block and small block Chevrolet distributors physically interchange with no problem (unless it's a tall deck block like a 502)
Will a 454 distributor fit a 366 tall block?
No, a 454 distributor will not fit a 366 tall block without modifications. While both engines are part of the GM big block family, they have different distributor mounting and drive configurations. To use a 454 distributor in a 366 tall block, you would need an adapter or to modify the distributor itself. It's essential to ensure compatibility to avoid issues with engine performance and function.
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.
What is the stock deck clearance of a 454 engine?
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.
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.
Is there a difference between 454 Chevy block and a corvette 454 block?
yes there is.
Are the intake manifolds on a 454 Chevy truckengine and a car 454 interchangeable?
I think the truck block has taller deck height but if rare I think can be machined to fit. Talk to engine builder before you buy.
Will a Chevrolet 454 distributor work for a 350 Chevrolet engine?
Yes, it will work. If the 454 was a tall deck design, you'd need to shim the distributor up .400" to mate with the 350 oil pump shaft.
How do you tell a 454 cubic inch engine from a 427 cubic inch engine?
the only real diff is 454 has a longer through on crank the appearance is all the same is it a car block or truck block a truck block deck height is higher than car block manifolds wont interchange or distributor if its a truck block throw it away it will say truck on the back below where trans bolts most likely a 454 and if u really want to know call the parts stor they will tell uwere to look for casting #. these engine's are no good unless u think u r going to run more than 500 hp or in a truck u r defeating the power to weight ratio concept.
