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!
