good cam

Whats a good cam for a stock form 302 HO motor with E7 heads that you guys recall from Comp cams, crane cams, FMS,..etc?

FMS b303 will give you a nice lumpy sound and a little bump in power.

this is stupid question here, how much hp increase roughly?

Something mild because an agressive cam's powerband will be higher than the stock heads can support. The E cam is a good cam for stock headed cars, maby a comp XE264 series. Honestly, I would at least port the heads while you are there. Also, the stock valve springs will not work too well with high lift cams.

I am not really sure but I know when it hits about 3000 rpms it starts pulling real hard till about 5200 which is perfect for stock head engine

Stick with the stock cam, the stock intake and heads cannot support airflow at high RPMs. If you do switch, pick a cam that makes peak power no later than 5000 to 5200 RPMs.

I had the Crane 2031 and it is good for about 5200 RPMs.

I'd say the Ford Racing E303 seems to be the most popular street cam where I'm from.

The B cam I wouldn't really call real agressive, but it is a higher end cam than not. I have the B sitting on 1.7's advanced 2*, makes power from 3800-6000rpm on the stock tach.

I used to work on my friend's old 1985 GT. It had a B303 cam and performer intake on it, all else was stock, and it made pretty good power. Nice combination.

Is the engine a hyd/roller engine or the old flat tappet (pre-85)?
