Are all IV Big Blocks the same block?
can a 396,402,427 be bored and stroked to a 454?
or is the 396 and 402 limited to a 0.100" overbore like the 427 and 454?

I dont think you can change them that much. I do know that you can change a 396 into a 402 just by boring it out a little.
All but the 402 can safely go 0.70 over, the 402 is a 0.30 over 396, personally I would'nt go 0.100 unless it was to resleeve
