Yenko ZL-1 block opinion (not selling, ...why?)

[DW31S]

I say "NO" on the snowflake. I know MacNeish well and if opinions mattered, I'd bet he would say leave it off....although it would "line his pockets" by adding it. There was (might still be available) an early '69 L72 engine for sale on Baltimore, MD Craigslist recently. Turns out I know the seller's father. Sounds like it was bought at the Chevy parts counter years ago. I thought about buying it for my 977 mile ex- Super Stocker, but I'm staying with the SS/H rendition= 396/350. I have the contact phone number if anyone wants it.
