Trying to get some info on a Holley carb.

Side says 4150
Front adjuster block 12423 with a 2 above it.
rear adjuster block 11038-6 with a small 2 above
Any info would be appreciated
Thanks

Holley list number is stamped into the side of the main body. Can't read it from your photos. All I can Make out is it's a 4150 HP series carb. Need the specific list number to get exact information

Looks like 82651 or 82751. My guess is 82751 after enlarging the photo.

I think it's a 750 double pumper...
