Holley/Demon Carb stumble

PRH said

The specs show those blocks to have the upper two holes at .031, and the lower at .033, whereas the original 4779 blocks that I used with the old Proform bodies would only have two holes at about .026.
That’s a pretty big difference in the emulsion package.

Been along time since I've actually had my hands on one of those metering blocks but that does sound like a bunch of emulsion.

Sitting here thinking about it...it seems the holes were in odd places compared to Holley blocks. I may not remember that correctly but that's what I think I noticed with a 383 chev on the dyno in probably 2001 or so. They dyno carb went 590 HP at about 6800 and the Demon went 520 around 5500.

After that is just tell the customer to pass on that stuff.
