Fueling a blower

[Stevie G]

If you are going from normally aspirated to 5# boost, what should be done to jetting/fuel flow?

[REJ]

The way I did it on my blown six was to install the blower setup and get it running and then worry about the jetting. I'm running a 600 Holley with vacumn secondaries with stock jets and a 3.5 power valve, and it runs fine.You will have to play with timing also. I'm also running the manual fuel pump and have not had a problem with not supplying enough fuel to the carb.
