Googled up a few things but only this below item for sure from the same group.
Note it has Jumbo Racing, not Jumbo's also the ad refers to F1?

Try and you may get lucky asking someone @ Shaver Racing in Torrance CA?

I believe that is a later 'Yenko' block. They made big-bore and high deck versions. Ive seen them with a snowflake but I believe typically on a Yenko block, it would not have a 'w' for winters..If I recall it would have had a snowflake with an L... going by memory

Interesting as it has screw-in freeze plugs, typical of production blocks, but I have Yenko blocks had them both ways.
