That's not correct. As Norm correctly pointed out, any engine can be stroked with either a custom crank or an offset ground stock crank. Either way also requires expensive custom pistons and rods. As I pointed out, you effectively get a stroked Olds 350 by replacing it with a big block Olds. Note that the original question asked about a 383. That's a Chevy-unique combination and may or may not be appropriate for a small block Olds. I'm guessing that the original request was based on hearing about a 383 Chevy kit and not fully understanding the differences between the SBC and the SBO, or why that particular displacement is the right one. The "magic" 383 Chevy combination comes from using an existing 400 SBC crank in a 350 block and boring 0.030" oversize. It's a simple combination that can be put together using existing parts - there's nothing magic about the number. If you want a larger displacement SBO, get a 403.
