talos,
Either the dual carb setup or the Webers will give a wow factor. Due to the things I've described, you probably won't be able to end up with a street oriented engine, wild sound, and Webers. However, you can go with the dual carb intake and put a little thump in the engine. You will probably lose some hp by going with the dual carb intake over the Weber setup.
zrayr,
You're very welcome on the valves. Good pieces....
On the Weber setup, I think I'll have to disagree with you. If you compare apples to apples, a correctly chosen and tuned single carb intake setup will make more hp, and I can play with the camshaft to easily win with the torque.
I've seen lots of comparisons between Webers and a regular setup, but it's always been a very biased comparison...i.e. a tuned Weber setup vs. a low quality dual plane intake...or a tuned Weber setup vs. an intake with an incorrectly sized carburetor.
I agree that a Hipo 289 will be low in torque, but there are many ways to get around that.
