327 Sb Stroke and Bore Questions Few different questions.
1) What is the max stroke that can be put into the Gen 1 327 SB? Could it be stroked to 4.125 or 4.000 or even 3.75? I am trying to maximize cubes in this engine.
2) What is the maximum overbore. Stock it has a 4.000 inch bore, could this be bored to 4.125 like a 400 block? How about if the block was filled?

.060 over will be a safe overbore, any more than that you should sonic test it. I think 3.875" is the biggest crank you can drop in there without altering the block. So the biggest bore and stroke combo you can do without a sonic check or altering your block will be 4.060" x 3.875"
