OK well i just got everything back together i got a rebuilt 302 .30 over and i also got a b cam in it. While i had everything apart i installed rear disc and cobra fronts but now it seems like i don't have any vacuum and am having a killer of a time pushing down on it. Any suggestions on how to get more vacuum out it also i have a 93 cobra upper intake so if i could plug it into a port with more vacuum that would be cool too. just need suggestions.

You probably need the Cobra power brake unit...The stock fox power brake unit(big round thing behind the master cylinder) doesn't work well with the 4 wheel disc and Cobra front calipers...
It's been I while since I fucked with one, but ask maybe someone who's done the Cobra swap will chime in....

When you installed the Cobra brakes, did you guy out the distribution block? If not, that will cause a problem. The B cam should not affect your vacuum output at all, so make sure you don't have a bad check valve as well.

i ran a vacuum check and i had 12inchs of vacuum what exactly is this distributor block stuff and help would be perfect. I can't figure out at all why i don't have any

I agree, the B cam should not have vacuum problems.
