dual carbs..i tink your large enough in the bores..i asked a friend about htis and he said a dual carb setup would help a lot, and probably a larger exhaust system.
I'm going to post a 2 barrel holly weber progressive on E-Bay in a few weeks I'll let you know when I do. It comes with dual port intakes, manifold, and a chrome air filter. Its used and will probably need a rebuild but i will be a lot cheaper than new.
I have a 1776 and I'm running two dual throat Weber 36 IDF's, with big valve heads and 1 1/2 inch exhaust and it runs pretty good. I picked up the Webers on Ebay for $300. You can use dual single thoats too, like Kadrons or the dual Solexes with chokes from CB Performance. With your displacement you can use more carberation along with a good exhaust.
