Holley/Demon Carb stumble

The first BG carb I bought was the predecessor to the Demon carbs..... the “Claw”.
It was a Gold Claw, which became the Race Demon RS(removable sleeve) when they changed over to the Demon line.
Mine was a very early production unit, which still used a Holley cast baseplate and Holley bowls that had the “Holley” lettering milled off, and then re-died gold.
There was a note in the box stating that when the bowls and baseplates were available they’d ship them to me.
They would have a call tag with them to return the old parts.

The new parts arrived some time later, but no call tag.
I called, they said just keep the stuff.
Those bowls and that baseplate went on my made from scratch HP950.

The point of the story is...... BG was using Holley baseplates interchangeably with the billet Claw pieces at the beginning.

Also, the BG carb kits used to say Demon/Holley right on the packaging.
I’ve used piles of those kits to refresh Holley carbs.
So, whatever differences there are in the baseplates and blocks, it’s not something that requires different gasketing.

I’ll tell you what though...... those Claw carbs often had some manufacturing issues that weren’t going to be “tuned” out of them.
I have a 750 Silver Claw here that someone gave me.
I’ve fixed(well..... hopefully fixed) a few issues I found, but have yet to try it on a motor to see how it works now.
