Yes. Specialized equipment required.
Bore it .030 over. A 350 has a 4 inch bore. When you go .030 over, the cid., becomes 355.
A small block Chevy has a 4inch bore. When you bore one 30 what you are doing is removing .30 thousandths from the cylinder. That would make the bore 4.030 or turn a 350cid into a 355cid.
Its a 355 cubic inch
Most builders feel it shouldn't be bored over 4.065".
You can bore a 350 .090 over, but the thing is the bore is so big that the cylinder walls are about a hair line thickness apart. In order for the engine to accept the bore and punishment of the shear power, the 350 Block must be casted with extra carbon to strengthen the block.
.030 is the max you can bore a 92 305 i dont belive you can bore more then .030 over Some blocks you can go .40 over but the cylinders start getting thin and if you are building a H.P. engine you will have problems with overheating
I've heard of going .060" over, but most builders feel .030" over is the limit.
Take off a cylinder head and measure the diameter of the bore.
Here's quick easy and simple answer 350ci is the total volume of all eight individual cylinders of the engine in cubic inches added together 350ci divided by 8 = 43.75ci volume per cylinder bored .040 over which means forty thousands of an inch overbore means that you enlarged the entire bore from top to bottom by forty thousands of an inch over it's entire circumference the reason it is done is because the cylinders have worn to the point that even with new piston rings the tolerances would be out of factory specs. so you bore it out .040 then you have to buy new .040 over pistons and rings then do everything else you need to do to put the engine back together and you have a Chevy 350 bored .040
