What is the casting number for a 454 block?
What is the casting number for a 454 block?
Have located a 454 casting number 361959 which the owner says is a 4 bolt main engine out of a 1980 truck. Anyone know if these two blocks are identical as I want to bore/stroke to 496 using my forged crank and pistons, and swap on the ported rectangle heads etc?
How tall are the 454 block hot rods?
Still researching potential deck height differential as I read somewhere a while ago that some 454s were “tall” blocks with a different deck height. Anyone know of any way of identifying them?
Is the 496 block the same as the 454 block?
Anyone know if these two blocks are identical as I want to bore/stroke to 496 using my forged crank and pistons, and swap on the ported rectangle heads etc? All the parts are good to go as the problem is a cracked block due to ingested mud hindering the drainage last fall.
What kind of camshaft does a big block Chevy have?
Big-block Chevys used both mechanical (solid-lifter) and hydraulic camshafts well into the late 1980s when factory roller cams began to appear. Flattappet hydraulic cams are the bread-andbutter cams of Chevrolet production engines.
Can you change the timing of a big block cam?
With the availability of original-spec replacements it’s just not wise or cost effective to consider a regrind even when you’re determined to duplicate original factory cam timing. Most big-block cams are interchangeable even across generation lines between Mark IV, Gen V, and Gen VI engine blocks.
How to choose the right camshaft for your engine?
Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Are you building an engine for everyday driving? For towing?
Do you need a grooved Cam in a 1965 Chevy?
Similar components are also available from all major cam manufacturers. One notable exception to cam selection is for the 1965–1966 396/427-ci engines. These early engines require a grooved rear cam journal. You cannot use an un-grooved cam in them as it would block a critical oil passage.
