Yes it is. I have both that new book and the old one that has a blue and green background. According to the above mentioned book the "big" 1-7/32 Venturi carb flows 287 CFM @3.0hg. After comparing other carbs, including the 50 CFM difference on Q-jets, I think that the real CFM should be around 300-305 @3.0 hg. Maybe I'm just splitting hairs and it really doesn't matter. One thing for sure the car runs a lot better and seems to have a little more power. When I get my exhaust done with the o2 sensor I can tune this the right way. I also took apart a junk 79 Dualjet and harvested the jets and metering rods. The rods in the junk carb are .051 with a .026 tip and the jets are #74 which is .074. I don't know yet what rods and jets are in the carb that I'm running on the car. It is a reman bought for me as a Christmas presant. Supposed to be for a 1979 267 or 305 V8. I should be pretty close.
