What are the specs? Some may know off the top of their head but most of us don't.

are you expecting enough vacuum to run power brakes? 302 is not very big.

FWIW, I ran the 401A6 in my 350, and it was on a 112 lsa. It was fine with my power brakes. Yours should be as well.

I changed my brakes to a hydraboost set up so I would not have to worry about vacuum anymore.

When I got my AFR Eliminator 195 heads, I wanted a cam with less split, and went to the 401A4. It is on a 108 lsa. So by switching cams, I found one best suited for my heads, tighter lobes for more power, and rpm range. It idles at 1050 in park, 850 in gear, and that it as low as I can get it for now, until I get my afr meter to fine tune the carb.
