On my aluminum 427 by Gessford Machine (454)
I have a 2X4 holly setup
The numbers on the carbs are.
C3AF-9510-BK-2804
C3AF-9510-BJ-2805
They have never been right, they always seem to be rich and run better on hot days, on cold days they really run bad. Today I started the car and it seemed to be running rich and possibly fouled one plug and dumped fuel all over the intake ( a puddle!). So needless to say I pulled the carbs and boxed them up and I sent them to Pro Systems. Has any one had any experiences with them?
I also noticed that the fuel pressure is a little high at 7- 8 lbs. Is this normal?
I have a mechanical Carter fuel pump, is there some kind of fuel pressure regulator I can add to adjust the fuel pressure?
When I turn off the motor I can see fuel continue to trickle down into the intake as the fuel pressure guage slowly goes to 0. This explaines the rich condition when I try to re-start the motor after going into the store. How do I correct this problem?
Below is a photo of the motor and the fuel log.
