dual quad

If you are using multi point injection it really won't matter. All that is going through the manifold is air.

X3 for balanced CFM, hieght looks. Only problem is the air filter assy (any dual quad huh) HEI fit varies with casting

Dammit!, Now I want one! :D (not likely, maybe when I get around to the 428)

Pontiac Offy dual quad had a substantial flow improvement vs the E-Stuff and Factory single 4 intakes at the time, (during a calibrated flow test on a Super Flow 1200 flow bench). This was years ago. Like 30 cfm better in a port to port comparison.

Tom, do you by any chance have any flow numbers from an Offy 5499? Stock or other?
