340 vs 383

Are there any 383 blocks still in existence. Lol. A nicely built small block will knock that 383 back into the last century.
I’m playing with one, aluminum everything, and I’m excited to see how it runs.

What’s the SBM advantage? If you do everything to a big block that you do the small block, how does it win out? Genuine question, and you know I respect the hell out of you and your opinion.
