I don't have the Chevy overhaul manual to look up the float settings for the internal, only, adjustable, floats on the 3811 on my '67 390 hp 427. Can someone give me the space between primary and secondary float and inside of bowl when bowls held inverted for this adjustment? Please specify whether measurements are made at toe end( part of float fartherest away from nedle/seat
) or "heel". I believe specs for primary are at toe and for secondary at heel for some reason.A Holley catalog gives general measurements as 7/74" at toe of primary and 13/64 at HEEL of secondary but don't know if these apply to my stock 3811. Also, what should primary jeting be for this carb only a few feet above sea level?
Thanks in advance.
