Subject: RE: [Chevelle-List] Two Barrel
vs. Four Barrel carbs...
I'm not a racer... I like people to see what I have
as I drive by and let their jealousy rise to an insurmountable anguish.
MPG is important to me. But maybe I should
explain my reasoning and let "The List" have the last word.
It all comes down to the fact that I don't trust
the carb that's on there. I'd much rather have something that I know is
going to start up every time. It's also acting like it needs a heat
shield. And from what I hear, they only make heat shields for 4
barrels. I've replaced the battery and it's got a new fuel pump so I'm
pretty sure it has to be the carb. At any temp over 180 it has a hard
time starting. After severely pumping the gas it'll start but I get a
big cloud of smoke coming out of the exhaust.
So I figure what the hell, just put a good 4 brrl
on there (W/ a heat shield) and all my problems are solved... right?
Thanks again,
JM

what kind of driving to do you do? if your not on
it all the time i would
think the 4 barrel
what help your mph! because if you look at the barrels on
a 2 barrel carb there are 2 great big ones duppin fuel, and
on the 4 barrel
there are the small
primaries and then the secondaries. you would have to try
and stay out of the secondaries to make this work
any one else can correct me if im wrong

I'd stick with a 2-barrel,,especially on a stock
307..Granted a 4-barrel with
smaller
primaries will not be as much,,"usually",,as a 2-barrels.....I'd look
up the CFM numbers on your 2-barrel too
before buying a 4-barrel,,,which I'm
not
absolutely sure what the lowest CFM rating is out there regarding
4-barrels,,600 cfm comes to mind,,,but
I'm not sure...I'd be suprised if the
307's carb flows more than 400 cfm,,guessing....
Not too mention changing the intake manifold,,,possibly
reconfiguring the
linkage,,automatic
tranny??,,then the kickdown if connected,,,fuel
line,,breather,,etc.,,etc...
g'luck!
