My 304 stumble

Well, I'm in luck then.  I have a "brand new" (OK, bought in '96 new, but 
used for one year) Holley #7448 model 2300 350cfm "off-road only" carb on 
my 304.. supposedly one of the more adjustable 2bbl Holleys.

I have no idea which power valve is in the Scout now.. but I also have an 
off-road spring-loaded needle and seat to install, and some different jet 
sizes to try for better economy and/or power.. so I'll pull the power 
valve while I do all of this, and swap up for a larger one.

What's the downside, other than the EcoNazi's war cry, to a larger power 
valve?  Will fuel economy drop if I keep my foot out of it?  Naturally, 
when I floor it, economy would go down... ;)

Thanks, Steve
