this has 89 primary jets, 116 secondary jets.
that's in thousandths, actual size.
want to jet it up ? drill out the secondary jets with an 1/8" drill bit
not kidding ....
that's what the Buick guys did for 30 years....
Buick intake manifolds are flat like a workbench,
the big 1000cfm carb would slow down velocity,
so the fuel could make the sharp turns, resulting in higher flow,
and make more HP
