Hi,
After
looking through some of the recent Holiday sale catalogs
that have
begun arriving (e.g. the OPG holiday catalog), I have a
few
miscellaneous carburetor questions that I was wondering if anyone
could
answer for me, as I don't have any experience working with them
and I
don't know much about them (I want to learn what I can in this
area that
is foreign to me before for when the aging one on my SS
needs any
attention!).
As background, I have a 69 SS with a 72
402 truck crate engine in
it. The car is mainly original and
basically stock except for a few mild
upgrades (e.g. 2.5" exhaust,
electronic ignition, etc.) & I'd like to
keep it that way
Here are my questions:
1) How many CFM were the factory
quadrajets used on bigblocks from the
69-72 time period? (I see that
OPG sells aftermarket Edelbrock
carburetors with 600 & with 750
CFM ratings that are said to fit 64-77
cars, but what were the
factory CFM rates? If I were to go with an
aftermarket model like an
Edelbrock, which CFM would be closest to what
came out of the
factory?).
2) What would be the differences between a 69 big
block quadrajet and a
72 big block quadrajet? (I see that Year One
sells only one Rochester
carburetor that they say fits 68-69 327s,
350s and 396/325 & 396/350,
while the Paddock sells a PAD01661
4bbl quadrajet said to fit 1969 all
trans / 350CID & they list a
different PAD01187 4bbl quadrajet said to
fit 1972 all trans / all
engines - given that I have a 1969 vehicle with
may be a 1972
quadrajet, would there be any real difference in these 2
carburetors
outside of possible visual differences and could their use
be
criss-crossed between 69 and 72 vehicles?).
3) Is there a
way I can tell exactly what year quadrajet is on my
vehicle
currently? (i.e. is there an identifying characteristic
and/or ID # on it
that I could see that would tell me for sure
without me having to take
the carburetor off it? Seems to me that
when I first bought the vehicle,
I looked for numbers but didn't find
much of anything that anyone could
decode for me).
4) Outside
of the Year One, PADDOCK and OPG/Edelbrock models listed
above, can
anyone recommend any other "national" specific sources/models
for a
replacement quadrajet for me? (and does anyone think I might be
able
to find a new or rebuilt one locally through my local auto
parts
stores / suppliers - e.g. NAPA and the likes of
them)?
5) When changing a carburetor, is there any other
miscellaneous h/w or
gaskets that I would need to replace? (I see
that OPG and Year One list a
heat insulator/heat shield that goes
between the carburetor and intake
but I don't see them list any other
gaskets or h/w - would I be able to
reuse the insulator/shield I have
& I if I do need to change a gasket,
where would I be able to
find one?).
As always, *thanks* for any info anyone can give
me!
