When I had my 350 re-built after I set my '69 on fire a while back, I had a slightly more aggressive cam installed. Since then have noticed that my braking performance on the highway is very poor. I'm reasonably sure it has to do with reduced vacuum at speed as a result of the cam; but how can I resolve this issue? Could it be something as simple (HAH!) as a new vacuum booster?
Thanks in advance for any insight. Roger
