362 cubic inches
The formula for the area of a cylinder is pi times the radius squared times the stroke of the crank. This is an 8 cylinder engine, so:
3.14159x2.03x2.03x3.5x8=362.493
Engine manufacturers always round up, so the answer to your question is 363.
It's exactly 360.42 Cubic InchesStock Stroke is 3.48 60 over is 4.060 BoreTo make a 383 stroker you need a 3.75 inch stroke crank, and 4.030 BoreActual displacement is 382.67 Cubic Inches
4.310
If my math is correct , just over 362 cubic inches ( 4 inch bore x 3.5 inch stroke , bored .060 inches )
4.06(bore)/2=2.03(radius)*2.03=4.1209*3.14159(pi)=12.94617(square inches)*3.48(stroke)=45.0527*8(# cylinders)=360.4216cu.in. Most engine manufacturers round up, so this would be a 361.
4.310 bore X 4.250 stroke -- basically a 454 bored .060 over with a 1/4 inch longer stroke crankshaft as compared to the 4.250 stock bore size and 4.000 inch stroke of a 454. Just as an aside FYI, 427's have the same stock bore size as a 454's but have a 3.760 stroke.

There wouldn't be enough deck height to get a 6" stroke. The longest I've seen is around 4", and that requires a special block. A .060" overbore with stock stroke would be about 360 cubes. With 400 crank, it would be 388.
If my math is correct : using a 4 inch bore and a 3.48 inch stroke , with the cylinders bored .060 , just over ( 360 cubic inches )
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.
a Chevy 350 bored .060 over would be 360.4 cubic inches
a BOSS 414!
I've heard of going .060" over, but most builders feel .030" over is the limit.
