Carb choice
Looking for suggestions for the best carburetor for a 1974 360 stock manifolds aluminum intake and small cam.
On the street?
the factory 2bbl.
EDIT;
think about it.
You didn't say;
1) that you pumped the compression up, 2) nor that you installed dual exhaust,
3) nor a cold-air intake,
4) nor a higher than stock stall, convertor
5) nor upgraded the gears into the high 3-series.
so, assuming that this engine is severely handicapped; including;
1) Say your cam has dropped the cranking cylinder pressure from the factory of about 133psi, to 127, which as we all know, will take the bottom end with it.
And so, yur engine cannot hardly break the tires loose, nor spin the tires very far.
Now say yur car still has the 2.76 gears , which will make about 35mph@3500 in first gear.
Not coincidentally;
3500 is about where that new cam will begin to make power, beginning at 1 hp. and
3500 is about where the big Holly 2-bbl runs out of cfm, on that anemic combo.
>>Now, examine your driving habits;
how much time will your street-car be spending in First gear at above 3500?
Is it worth it, to you, for over $1000 smackers (for new parts), to stick a 4bbl on there, for the few times every summer, when you wind her up past 60mph in first gear; or kick her down into first at say 50 mph.and you still want to stuff those hot cfms, now occupying several times their original size, into logs, and probably, the anemic factory y-pipe and single exhaust?
The point is this;
If I was in your shoes, here's what I would be doing;
MY
next purchase would be at least dual exhaust, then a 2800 convertor, then something like 3.73gears, and then headers for icing on the cake.
Now that combo will be ready for a 4bbl.
I mean sure you can install a 4bbl, but for the most part, she'll be all bark and no bite.
Don't believe me?
Be sure to do some before and after testing, keeping the rpm below 3500.
or not.
