Was wondering if someone with more experience than me might be able to shed some light on an intake question. I have a mild
390 with an edelbrock performer plus cam. I want to run a quadrajet carb because of the tiny primaries hoping that because they
are so small the signal will be strong enough to atomize the fuel enough to overcome the larger runners and plenum of a streetmaster
single plane intake. I don't plan to run a spacer so not to increase the plenum size. I have a t85 with OD trans so I am concerned with
engine speeds of 2 to 2.5 grand, and also 3.5 to redline when my foot is in it. It is in a 3600lb ranchwagon. Rear gear will be 3.7 or so
when I change it. I own the streetmaster.

The Streetmaster intake manifold has some of the smaller ports of the FE intakes, and a small plenum that was designed during the fuel crisis '70s to be a good mileage/performance compromise intake. Check the runners for slag left from the casting, since some of them can be pretty rough as cast. It should have a strong signal on any carburetor under 750cfm, you use with that camshaft. Joe-JDC

thanks Joe, that's exactly what I was hoping to hear
