I'm trying to find out the same thing. Prices are very high and large snout cranks are not in stock anywhere that I can find.
Looking at the front of the engine. The engine/ crankshaft will turn clowkwise.
400 block, with a 350 crankshaft. 383 cid.
By the part number. Probably be a 39, series number.
It will be at 12oclock stright up.
A 383 is a .030" over bored 350 small block with a 400 crankshaft. The 454 is a big block.
You need to use a gear puller, as it is a press on, taper fit.
A small two-jaw or three-jaw gear puller works fine.
Itis mounted to the front face of the engine block right behind the crankshaft pulley and often covered by a small shroud. You can usually see the wires leading to the connector plug in that area, at bottom of the crank pulley.
Small block
It is a small block
From the factory there were no supercharged Fieros. Only 2.5L 4cylinders and 2.8L V6s. There are many kits available to drop in superchargered 3.8L V6s, or small block V8s, even Cadillac northstar V8s.
"The v8 350 is a small block Chevrolet motor.....................it became a big block at 396cubic inches......so anything smaller is a "small" block" this is a little misleading. a 350 is indeed a small block. a 396 is indeed a big block. but you can have a small block that is (internally..cubic inch wise) actually larger than a big block. for example GM made a 400 cubic inch small block. internally it is a larger engine than a 396, but the outer dimensions of the 396 are larger than the 400 small block. and the external dimensions and cylinder head design are what make a small block a small block, and a big block a big block. a small block engine simply has a physically smaller block...a big block is called a big block because it's block is bigger than that of a small block.
