A 348 Chevy engine has a stock displacement of 348 cubic inches. When the engine is bored .060 inches over, the displacement increases due to the larger cylinder volume. This increase is approximately 5.1 cubic inches, bringing the total displacement to about 353.1 cubic inches. Therefore, a 348 Chevy bored .060 over is approximately 353.1 cubic inches.
I've seen pistons that were .060" over. Any more than that would probably not last very long.
.060 acres = 2,613.6 square feet.
Bore it out to the maximum "safe" bore (.060" overbore) which is 3.935". Stroke it to 3.25". This is the stock stroke for the 327 engine, which is the only other engine to have the smaller journals. Rod Journals are 2.00", Main Journals are 2.30".
It would probably be close to a 340 as the 340 is the same engine block as the 318. The stock 318ci has a 3.910 in. bore with a 3.31 in. stroke the very same stroke as a 340ci. The stock 340ci has a 4.04 in. bore. The .060 in. over bore would result in a 328ci engine. The formula for this is, 1/2 bore x 1/2 bore x 3.14 x stroke x number of cylinders.
Yes, 060 is greater than 045

360.42 Cubic inches. Math people. Pie (3.14) times the radius (stock Chevy 350 bore is 4.00, .060 over is 4.060, radius = 2.030) squared. Multiply by stroke, stock 350 is 3.48 in. then multiply by 8.
