Two fours will obviously not be as good as a single four barrel, but we all overcarb our rods for the cool factor. If you play with jets you should get it to be very reasonable performance wise. As for performance, honestly it is hard to use much in a light, short wb t bucket. I got my foot deep in mine coming out of a rest stop to merge with traffic on I 4, and the upshift to 2nd lit em up and scared me a little. In normal driving you won't even get into the secondaries.

I like the idea that you have and know the history of the engine too, that helps a lot. Keep us posted.
