Marx3:
And which are the feed holes?
The fill holes or the discharge holes?
Or the holes at the bottom of the tubes?
77cruiser:
I'd open the discharge holes a bit. Do you know what size they are now?
Marx3:
Havent measured them.
As far as I remember, the carb is a late 70's pontiac unit, that would propably have come off a 400.
I'll get by the car and have them measured asap.
What size, should I be seeing?
Marx3:
discharge holes measure in at about .052.
The next size drill bit I have ( right now ) is a .058, so I didn't enlarge them yet...
77cruiser:
What hanger are you using?
