Holley 4777 carb ( 650cfm double pump) setup for blow through.
Was used on my 318 with ~7lbs of boost.
I ran it with the 650 main body and then moved up to the 750 HP holey main body instead of cutting the choke horn off to fit the carb hat i had.
It ran good, didn't have any problems with the carb.
No longer need it since I'm going back to an NA motor.
Fuel level sight glass
Center hung Nitrophyl floats - Won't collapse under boost.
Jet extensions
.120 Needle and seats
50cc accelerator pump
Power valve channel restriction drilled out to 5/64".
All the hanger18 mods to the carb can be found here.
