I found that the 326 has the same stroke as the 400. If I bore my 326 will it be a 400, is it the same block and able to bore that much? 3.7199 to 4.1222

The blocks have the same outside demensions, but you cannot bore a 326 or a 350 to make a 400. There isn't enough cylinder wall.

cant go that far.Tom

You won't even find enough material to get to the 350 bore size before the water jacket.
