Preferred carburetor for mild 360?

If you just installed the Pertronix ignitor conversion kit it didn't affect the timing at all. All it does is replace the points or factory electronic pickup. With that said if you do what crackedback said it'll make a world of difference in how it idles, cruises at low speed, and even help the fuel economy some. I've done it to numerous cars over the past 30 yrs. including Chevy's and Ford's too and always get the same result.
