help id holley
 

trying to see if I can id this holley,i realize it has been modified only numbers I see are metering blocks are 11183 and 84
base plate is 10747

thanks

By the diameter of the butterflies it's a 850. That's a place to start at least.

If you remove the baseplate, there may be a number stamped on the top of it, near the front. That could help narrow it down some more.

That is a 0-9381 830 cfm competition double pumper

Bentley, you're amazing. How did you know that?

great, thanks to all, instead of starting a new thread, I want to sell it, id like 300.00 for it, I am thinking its too big for a 327
