Dave-
I'm sorry to hear about your Dad. That's gotta be rough. There are some pretty smart people on this site, who will be happy to help you. You can email me if you need to (
pkrwuds@pacbell.net ).
Don't forget your Holley parts too! You'll need a power valve (probably a 65), and a bowl gasket and a metering plate gasket.
One more thing, no matter where you ask for info, who ever it is that gives it should be able to explain it so that you can understand why the solution is what they are suggesting. If they can't, then verify the info with someone who can, before acting on it.
Take care,
-Chris
