Ken:

I have a set of 722's done by Booth-Arons (sp?) in the 70's. The have had extensive welding (roofs raised and pushrods moved over .100"). I'm told that even back then, with titanium valves, etc., there was over $4000 into these things. I know next to nothing about the operation of a flow bench; I'm just reporting what information I have.

Anyhow, to confirm what Gach has been trying to hammer into everybody's heads (the Edelbrocks are 320" capable with little effort), the numbers that Brandywine flowed with these heads two years ago isn't all that impressive. I'll give .300, .400, .500, .600 and .700 #'s. These numbers were at 28" and without an intake manifold attached; just a wooden adapter funnel.

.300": 207.0 int./163.5 exh.
.400": 260.4 int./193.5 exh.
.500": 298.8 int./213.0 exh.
.600": 314.4 int./222.6 exh.
.700": 308.0 int./223.8 exh.

As you can see, at .700", reversion took place with the intake losing and the exhaust barely picking up either. If you compare these iron head #'s with those that Lou has told me he achieved with about 60 hours labor (the first set is always the most time-consuming), it makes little sense for a guy without class constraints to favor iron over aluminum heads. Lou has mentioned that Brandywine will provide port work to flow these numbers for about $800. You do the math.
