a fellow holley carb guy i know has gone through a holley #3916 3 bbl - his info . but he could not locate a new secondary vac diaphram . to me it kinda looks like similar setup to a holley 650 spreadbore but there may be a dif ? any ideas ? any info appreciated .
no you cant find one, what we been doing last few years, is taking the whole vacum assembly of a 3310, adding the qhick change top and installing it on the 3 barrells, so for it has worked out perfect on my race cars and my street cars, plus the added adjustibilty w it, allows to completly work tht inhernt over carbed bog out, i have 3 of those carbs, my mopar buddy is running 3 of em also,
yeah not sure on the cfm . ( edit : 950 cfm I think from info I found ) ok , I'm following that pretty much . so it bolts up the same , just looks dif . dif angle ? does the rod length down to pivot seem close enough ? I will pass on that info . thanks .
