Yes you can and if you go to the Autolite carb I've been told it even gives you a better intake setup . I'm not sure I believe better but I'd do it unless I had a show piece.

If your using the stock air cleaner that puts the filter off the passenger side valve cover, it'll probably fit. If you have a generic filter centered on top of the carb, you may hit the hood.

I did away with the EGR plate, so the difference isn't much but didn't measure. Did a 1" body lift for the NP435, so really wasn't concerned.

I use a Moroso adapter for the Holly 4500 series carbs. You have to use a thick 2 barrel gasket to clear the accelerator pump on the Autolite 2100's. It's a lot nicer adapter and the corners won't break off like the cheap Mr. Gasket cast pieces for 1/2 the price. It'll pay to do it right the first time. Here's a link to it.
