440 Tunnel Ram Help

depending on how racey you drive it on the street, i have 660s on my 418 street car, they take some getting use to, yes they like wide open. id say if you really like getting it on the street id look for 2-650 double pumpers, then buy 2 holley or pro form main bodys ,they are like 125.00 a pop, they have the air horns milled, and have screw in air bleeds, you can probably start lookin now and get a 650 for 100.00 bucks or so on craigslist/ebay/jaxed , then you will have a nice pair of carbs, someday i would like to get 2-e 85 750s, my carbs are side ways, im going to redo my fuel lines this winter, and make a air -pan and seal it to the hood, later brian .
