4.030
A 355 is just a 350 bored 0.030 over. There really is no difference. this is true but to further the answer if only you bore the cylenders out in the block you will need to buy aftermarket pistons to make up for the new wider space so you dont have compkications with the pistons slapping the cylender walls
355.
a bored out 350 blockThat answer is right, but it did not answer your question completely.A 355 is a 350 block that has been bored .030 / thousand oversize from factory stock bore. Nothing special.
Bore it .030 over. A 350 has a 4 inch bore. When you go .030 over, the cid., becomes 355.
The bore of a 355 engine typically refers to the diameter of its cylinders, which is usually around 4.00 inches (101.6 mm). This engine is commonly associated with the 350 cubic inch small-block V8 engine from General Motors, which can be stroked to achieve the 355 cubic inch displacement. The 355 is often used in performance applications due to its balance of power and reliability.
Its a 355 cubic inch
TH350, unless you want an overdrive, then, I would go with the 700R4.
Chevrolet never made a 354 big block. So is say the difference is that a 496 is real and 354 is not. there is talk of a 354 small block but they are all from UK and id be inclined to say they are actually talking about a 355.
a 357 Chevy is a just a smallblock 350 Chevy bored .040 over for a total CID of 357, just as one bored .030 is a 355 Chevy. a standard rebuilt 350 is generally bored out during the rebuild process to usually 355, sometimes 357. right now i have a 357 Chevy in my 1970 chevelle
A 355 small block engine should use either 10w-30 or 5w-20 viscosity motor oil. They provide a good balance of protection in most driving conditions.
There will be a cap on the valve cover. Usually the drivers side, but, it varies.
you have to bore out the cylinders .003 of an inch
