Carb is a 950DP 4150, it was originally a holley 850DP that has been converted to a 950 with a proform main body (choke delete and is worth 25-50HP). Carb has been completely rebuilt and has seen 300 miles on my 521 BBF In my 87 firebird.

Carb Specs:
1.)holley 850DP bowls, base plate (NO throttle slop) and metering plates (4 corner idle)
2.)30cc primary accelerator pump, 50cc secondary (both rebuilt with new umbrella seals and pump diaphrams)
3.)Primary Bowl has new Holley viton needle and seats, and new AED nitrophyl float with 6.5PV
4.)Secondary bowl has new holley viton needle/seats and a new Holley nitrophyl float that is notched for jet extensions. secondary has jet extensions, The seondary PV has been plugged but I will also give a 6.5PV along with the plug to the buyer.
5.) All new AED nylon gaskets (needle set screw gaskets, idle screw gaskets, fuel bowl screw gaskets)
6.) .032" Highspeed air bleeds and .075" low speed air bleeds (screw in type for easy changing)
7.) PROFORM HIGH PERFORMANCE MAIN BODY! 950CFM (with screw in air bleeds!)

Again this has about 300 miles on my 521 BBF and its running great, Im only taking it off bc i need a bigger carb for my upgrades. I have alot of money in this carb, the main body alone is 200$. THis is a running carb! Im asking 350$ plus 10$ shipping (to continental 48states USA) but the price is negotiable

 

come one guys! make me an offer!
