Carb too big?
I agree 100%.
It's funny though, whenever I throw that formula up here, I get railroaded. lol
All CFM's are not the same,that is the problem with discussing them,a basic lack
of understanding the differences.There are two main problems, carb. ratings,and engine
demand. Pish threw out those OE carb ratings 1bbl,2bbl,and 4bbl holley together,which
is a misleading cluster of numbers. Most OE & aftermarket 1&2bbl carbs are flow rated at
3.0"Hg,but a couple of OE's were rated @2.0"Hg,4bbls are rated @1.5"Hg,apples,oranges
and pears!Not to mention some OE ratings were "wet" flowed then dry flowed later chang-
ing the rating for the same carb!Add to that a very non-standardized industry-wide test
equipment method and all those numbers from the last 50 yrs. can be more than a little
misleading. Max perf. efforts target no more than .75"Hg intake depression at peak RPM,
(think engine masters challenge),which means it takes a 1050 dominator to supply 750CFM
at .75"Hg. The problem w/that is the tuning becomes critical and difficult,it is not for the
avg. driver/hotrod.
