Starved For Fuel?

[ssscamaro]

fuel filter in bowls if still equipped.
Float levels!! Does the carb have secondary jet extensions? If so it MUST use a notched float. I had a 69 camaro holley carb without extensions going 1080s 124 put jet extensions in it and fell on its face 900 or so feet. the rear float couldnt drop far enough to let enough fuel in to replenish what was being used. Put in notched float( i always run my holleys with fuel right up to bottom of sight plugs and just a littel tricle if you bump the fender)set level and 1 tenth better 60 foot and 1070 127 mph...

by the way i Have a stock Y block that i drilled and tapped for 1/8 npt on the bottom side. ran my fuel pressure guage in it a few times to see what WOT was reading. after i was happy with that took off guage and put a 1/8npt plug back in that you cant see unless you take Y block off.

also i have seen the old fuel sending unit 'socks" melt into mush with age...did that get replaced??
